Red Ceibal COMMON NAME- Chanchito - Red Ceibal FAMILY- Cichlidae See the Photo Gallery on Page 15... ORIGIN- Uruaguay – the Arroyo Ceibal in Centurian which flows into the Rio Yaguaron at the Brazilian border TYPICAL SIZE/COLOR- A medium sized cichlid the males grow to 7” and the females to 5”. They have primarily gold bodies with black irregular vertical bars. During spawning their colors intensify to a bright red-orange with green vertical bars and bright blue spots on their dorsal fins. They have brilliant red eyes. TANK TYPE/SIZE- These fish should be kept in a heavily stocked large tank (125 gal. or larger). It should contain a sand substrate (their habitat contains dark red sand), plants and some caves for spawning to resemble their natural habitat. DIET- These fish are omnivores in nature, and as such, will accept all sorts of foods from frozen foods to flakes and pellets in an aquarium WATER PARAMETERS- Being from northern Uruaguay, they are not a tropical fish they appreciate temps from 60 to 75 degrees. Most aquarists keep them at room temperature. They do well with a ph close to neutral ( 7 ) and water that is not very hard. TEMPERMENT- This is a fairly aggressive cichlid. The level of aggression can be tempered by including a number of fish also native to their natural habitat (Crennicichla lepidota and punctata also Gymnogeophagus labiatus and rhabdotus SEXING- The males and females are similarly colored and shaped and aside from the difference in size as adults they are hard to distinguish. The best bet is to buy 6 or more juveniles and let them figure it out in time. BREEDING- These flashy cichlids can spawn at sizes much smaller than their full adult stature. They will spawn in a cave if it is provided or a hollow log. As is the case with many other Chanchito’s both the male and the female defend the eggs and fry. Provide the fry with baby brine shrimp or high protein micro pellets until they can accept flake food. These flashy fish are fairly new to the hobby but they can be found at fish clubs that have active BAP members. (Nancy Villars just had a spawn) There is something magical about a tank with territorial fish.

Even if you are a beginner aquarist, you can find striking fish species that will look great and add colour to your aquarium. If you make sure to keep the water quality at optimal levels, provide your fish with a stress free environment, and feed your fish suitable foods they will display their best colours. Unfortunately for many fishes, artificially coloured fish have become increasingly popular in the aquarium trade. As mentioned above, the natural way of enhancing the coloration of a fish is to provide it with ideal conditions. Many fish producers have instead started to create colourful fish by injecting them with artificial colour or dipping them in dye. The so called Painted Glassfish that is commonly found in pet shops is for instance an almost colourless fish species named Indian Glassfish (Chanda ranga) that have been injected with brilliant colours. Problems with dyed fish So, why is painted fish a problem? Well, it is cruel to the fish and to the unsuspecting aquarist. The fish will of course suffer during the various treatments (you can read more about the details further down in this article) and also become much more susceptible to illness, which greatly reduces its lifespan. Some dyeing methods cause up to 80 percent of the treated fishes to die during or right afterwards, but since 20 percent survive long enough to be sold to aquarists the treatment is still profitable. In addition to being hurt and stressed, dyeing can cause young fish to be stunted and never reach their full size. The aquarist will purchase a stunningly looking fish that gradually looses its coloration as the dye metabolize. Estimations show that roughly 90 percent of these painted fishes loose their colours within a few months, but this is actually not the biggest problem. The main thing to worry about is instead the increased risk of infections and the drastically reduced life span of dyed fish. Since the dye makes the painted fishes susceptible to various health problems, they will usually die young and force you to purchase new fish. Introducing a very sensitive fish to the aquarium is also unfair to the other inhabitants, since the weakened fish can function as a breeding ground for a colony of malicious micro organisms that eventually grows large enough to start infecting the other fish. Fish death is of course something unavoidable in the aquarium as well as in the wild, but introducing a fish that you know might die very soon is still not a very good idea. If you do not notice the dead fish it will start to decompose and seriously pollute the water. If this happens when you are away during the weekend, you might come back to a very lifeless aquarium. Always selecting healthy and strong looking fish is therefore very important even when it comes to non-painted fish. Painted fish are often sold to less experienced fish keepers that are attracted to the vibrant colours without realising that they are unnatural. When the fish turns belly up in the aquarium, the novice aquarist thinks that it is his or her own fault and never complains to the seller. Chances are, the aquarist will even go back to the same store and purchase even more painted fish, hoping that he or she will manage to take better care of it this time. Painted fish are also known as juiced fish, artificially coloured fish, or dyed fish. Fish can be coloured using several different methods. The three most common methods are dye injections, dipping and coloured food. Dye injection During a dye injection, a needle is used to inject dye under the skin of the fish. Just like when a human is tattooed, only a small area of skin will be dyed from each puncture. A large amount of punctures is therefore necessary before the desired coloration is achieved. This is of course very stressful for the fish, and the punctures can easily become infected. As mentioned above, the Indian Glassfish (Chanda ranga) is one example of a fish that is commonly dyed using dye injections. A dye-injected Indian Glassfish is much more susceptible to cotton fungus than a non-dyed Indian Glassfish. In this fish, the common forms of dye will metabolize within 4 to 20 months. How long the fish will stay colourful will depend on the particular fish, which type of dye that was used and how concentrated the dye was. Continued on Page 11...

Dipping Many fish species rely on an outer slime to protect them from injury and infections. During dipping, the fish is placed in a caustic solution that removes this mucus from the body. The fish is then dipped in dye, or injected using the needle method described above. When the dying process is over, the fish is dipped in yet another solution. This solution consists of chemicals that are known to irritate the skin of fishes, since the irritation will stimulate the fish to produce a new slime coating. Anyone can understand how stressful these various treatments are for the fish. Colored food It is perfectly natural for many fish species to develop new or enhanced colors when they consume colorful food. In the wild, many fish species will happily gulp down colorful shrimps, red algae, plankton and krill. Using this naturally colorful food types to enhance the coloration of your aquarium fishes is usually not a problem. Even if krill can not be found in the native waters of your particular fish species, they may very well do great on a diet that contains krill since many fish species are opportunistic omnivores that can eat a wide range of different foods. Today you can even purchase prepared fish food that will enhance the color of fish. Many of these foods have been specially made to suit a particular fish species, and will therefore not only contain colored food particles (such as shrimps, red algae, plankton or krill) but also be balanced in order to satisfy the nutritional needs of that particular species. So, using food to change or enhance the coloration of a fish does not necessary have to cause health problems for the fish. The problem occurs when fish producers start feeding their fish food that contains unhealthy and unnatural dye. Unsuitable dye will weaken the fish and make it less resilient towards disease. Unsuitable dye can also affect the growth and development of a fish, which is especially problematic since it is usually young fish that is fed this type of dyed food. If you purchase a fish that has been dyed using food, you should be aware that the beautiful colors will vanish as soon as you start feeding the fish normal fish food. This is true regardless of whether the food is comprised of natural color enhancers like krill or consists of unnatural and dangerous artificial dye. How to avoid getting dyed fish in the pet store Many different fish species are dyed. If you do not wish to purchase dyed fish, the best way of preventing it is to research the species you are interested in before you make any purchase. Visit the library or look up the fish on the Internet. This way, you will find out if those neon green streaks are a natural part of the fish's coloration or if they must have been created using some form of dye. The word “painted” in the name of a fish that you find in the pet store is naturally also a warning. If you wish to avoid dyed fish, you should be extra suspicious when you are offered to purchase fish with names like “Painted Glassfish” or “Painted Corys”. Dyed fish are however sold under many other names as well, including the common name for the un-dyed fish. Continued on Page 12... The Shoreline Page 11 Continued from Page 11... Examples of fish that is commonly dyed: Bubblegum Parrot or Jelly Bean Fish sold under these names are dyed versions of the Bloody Parrot fish. The Bloody Parrot does not exist in the wild; it is a human made hybrid that has been created by crossbreeding several different colorful cichlids. The Bloody Parrot cichlid is not a red color variation of the Parrot cichlid (Hoplarchus Psittacus). Bubblegum Parrots and Jelly Beans are dyed using bright colors like purple, green, red and blue. Their immune system is often damaged by the dyeing. Blueberry Oscars Sometimes albino versions of the Oscar fish (Astronotus ocellatus) occur, and it is these pale fishes that are injected with blue dye and sold as Blueberry Oscars. The Oscar fish comes in several natural color variants, but brilliant blue is not one of them. The albino version can naturally be injected with other colors as well, so before you purchase a colorful Oscar it is a good idea to find out whether it has been dyed or not. By purchasing a healthy Oscar instead of a dyed one, you can get a fish that stays with you for 15 years or even longer. Fruit tetras Fruit tetras are White Skirt tetras that have been dyed using the dipping-method described above. The White Skirt tetra is an albino version of the Black Skirt tetra. Fruit tetras can usually be obtained in a wide range of pastel colors. Many pet stores give the fishes names after similarly colored fruits, hence the name Fruit tetras. You can for instance find Grape tetra, Blueberry tetra and Strawberry tetra. During recent years it has even been possible to obtain Holiday tetras that have been dyed to fit the upcoming holiday, e.g. red Christmas tetras and blue and red 4th of July tetras. Painted Cory Dying the tail of the Cory is the most popular variant, but some fish producers dye other parts of the fish as well. Painted Botia Blue Botias can be found in the wild, but fish stores have instead retorted to selling dyed blue Botias. A natural Blue Botia can also be dyed to enhance the color. Painted Glassfish As mentioned earlier in this article, the Indian Glassfish (Chanda ranga) is frequently dyed using brilliant colors. Since these fishes are quite colorless is their natural form, the dye will produce a sharp contrast and stand out very clearly. Fluorescent glassfish is very popular, but the artificial colors will of course gradually fade until they have vanished completely. A high percentage of the painted Indian Glassfishes die when they are being painted, or right afterwards, and those who manage to survive become highly sensitive and prone to infections.

The Shoreline Page 18 An Introduction to Freshwater Stingrays By David Webber (www.freshwaterstingray.com) In the last few years freshwater rays have become increasingly available and popular and tanks have become larger and cheaper, making them a reasonable pet for the dedicated home aquarist. Although some other major rivers around the world have ray populations, most freshwater ray species are found in Amazonia, and as with its other flora and fauna, the Amazon system has an abundance of ray variants found all along the river and in many of its tributaries, from Peru and Colombia in the West to the mouth of the Amazon in North Eastern Brazil. Some ray species are also found in other tropical South American rivers with no direct connection to the Amazon. Stingrays are very ancient species, tracing their evolutionary history as far back as 300 million years. Evolutionary History The most commonly found species in South American rivers are Potamotrygon. There are also rays known as China or Coly rays, about which little is known at this time. It is thought that all of these Amazon rays are most closely related to Pacific Marine rays. Their isolation would have occurred when the Andes Mountains rapidly rose up about 15 million years ago, blocking the Westward flow of the river as it then was and forcing it to flow east all the way to the Atlantic, trapping many rays in the new system. This isolation and the Amazon’s tropical climate and seasonal massive changes in water levels created ideal circumstances and great pressure for evolutionary changes, as represented by the huge variety of stingrays found in just the one system. Even individual species that are found along the whole river, such as Motoros and Histrix, are polymorphic, each exhibiting their own wide range of colors and patterns as habitat and available diet change subtly between regions. A word of warning about a stingray's stinger Stingrays are so-called for their serrated, dagger-like stinger located on the top of and lying flat towards the end of the tail. Usually sheathed in a layer of skin and not always easy to see, this effective defense weapon is made of a protein complex , and is accompanied by a nasty venom usually released when the skin sheath of the stinger is ruptured. If the stinger cuts you it can cause large local blisters and intense burning throbbing pain. The immediate treatment for this is to immerse the wound in water as hot as can be tolerated, which helps to neutralize the toxins. This is not always possible, especially on the river. The traditional first aid treatment there is to urinate on the wound which works because urine is both hot , sterile and slightly acidic. Amazon folklore says that it must be a virgin who pees on the wound, leading to the joke 'there is good news and bad news......there are no virgins in Brazil'. Although extremely painful the ‘sting’ is rarely fatal unless by some bizarre accident it is in the chest near the heart, a tragic event which has been recorded as a fisherman was pulling a caught ray onto his boat. Fortunately for the aquarist even the feistiest ray is not normally aggressive with its stinger, though rays can be very accurate with their aim, either slashing or stabbing with their powerful tails. In Amazonia most casualties happen when a ray is stepped on as it hides under the sand basking and snoozing during the day and so most stings are on the feet or lower leg. Rays would much prefer to move than be stepped on so locals know to shuffle their feet or poke the sand ahead of them with a stick when in the water, so that a ray can sense the motion and move out of the way without incident. For hobbyists it is the opposite, most people get hit on the hand or arm as they mess around in the aquarium while cleaning the tank or moving the ray. Sometimes it is a pure accident, others it is from carelessness handling the ray. Even on a dead ray the stinger is still toxic and very sharp. Continued on Page 20... The Shoreline Page 19 ...Continued from Page 19 Types of rays kept by hobbyists The majority of rays kept by hobbyists these days , and the main focus here, are Potamotrygonidae, species of Elasmobranchs which are found exclusively in freshwater and includes more than 22 distinct varieties. At this time there is a lot to be learned about the relationship between these different varieties, whether they are subspecies or how closely they are related to each other. There is a dramatic and beautiful range of size , patterns and colors between them . Black rays with striking polkadot patterns, such as the Leopoldi, Henlii and the less common small spot Itaituba Black rays are found in Brazilian Southern Amazonian clear water rivers. Two of the more dramatically patterned types are Tiger rays, named for their striking patterns and the markings on their tails, found in Peruvian Amazonia and the similarly patterned Flower rays, found in Northern Amazonia in some of the Colombia/Venezuela/Brazil border region rivers. There are many other local ray variants that are not as beautifully patterned but still are interesting. Castexi rays, one of the most polymorphic rays, with large array of distinctly different body patterns, are mostly found in the Western regions of Amazonia, with morphs such as Otorongo (translated: Jaguar), Motello ( tortoise), Hawaiian, Tigrinus and others, all named for their beautiful patterns. The debate on species differentiation There is some debate concerning the different variants within species like Castexi and also the Black rays about how closely related to each other they may be. Whether they are truly separate species or are simply color morphs from slightly different habitats that would be expected to produce slightly different characteristics. Leopoldi, Henlii and Itaituba Black rays are prime examples often invoked in this debate, and their ability to easily interbreed throws more confusion on the whole subject. They are normally found in, and separated by, different Amazon tributaries. Leopoldi are found in the clear waters of the Xingu and Henlii are found in the waters of the Tocantins, clearly separate habitats according to the maps, but when the high water season is there it is impossible to know how different species are moved around by the massive inundation of floodwaters or if & how they migrate into different systems when water levels permit, only to become isolated again when the seasonal floods recede to lower levels. So it may be possible to find a species that may normally be only found in Peru or Colombia all the way down river in Brazil. It may also be that many of the species are in the middle of an evolutionary spurt, developing into new species. ‘Hybridization’ ( if they are actually separate sub -species) also seems to be a regular occurrence when natural circumstances permit and viable offspring suggests that Potamotrygon are not separate species. Continued on Page 21... The Shoreline Page 20 ...Continued from Page 20 Stingrays - a pest to some, a beauty to others "In the Amazon all things are possible". During the low water season, when fish are concentrated in small areas and main river and Igarape channels, it is relatively safe to travel to remote areas to investigate ray population distributions; but this season is relatively short, often as little as 4 or 5 months only before the new rains start and the water levels rapidly and dramatically rise again. Much of Amazonia is still unexplored, and river courses change making it impossible to be absolute when it comes to discussing Amazonian fish populations and distributions. Some ray populations are booming to the point where they are considered a pest on the sandy beaches of the river. People are employed on popular river beaches in Brazil to keep the beaches clear of the rays, which tend to congregate in ‘dormitories’ to bask just under the sand in shallow water during the day, just the place where bathers walk . Basically those rays are killed as a pest and left to rot and feed the scavengers. There is a certain irony in this as those same rays could be sold alive to the aquarium trade instead and generate income. Some ray varieties are only found in limited areas and are not common, such as ‘Pearl’ rays. Rays are also an important local food fish . These are both contributing reasons for annual stingray quotas out of Brazil. However, these quotas often produce paradoxical facts. As a food fish many rays are worth much more alive to the aquarium trade than they are as food. One Henlii , Leopoldi, or Pearl ray, sold alive, is usually worth more on the aquarium market than a meat animal that might feed a whole village for a week or give milk for a few years. With a few exceptions, most ray species are plentiful in their native habitats and are considered pests, which contributes to an attitude that it is OK to smuggle rays out during the off-season or when all the quotas for aquarium export have already been filled. The laws of supply and demand fuel this market, with the final retail price for them adding incentive. Smuggled rays are often more expensive and usually less healthy than those that are exported through legal channels because of the extra ordeal those smuggled rays have to endure when exported this way. There are many tales of rays (and other smuggled flora and fauna) being hidden inside adapted gasoline cans or under floorboards aboard fishing boats. Luckily they don’t fit into people’s pockets. Tank size, tank mates, and feeding One of the attractions for keeping rays in the aquarium is their behavior and intelligence. A healthy ray can learn very quickly how to recognize and hand feed from its owner. Hand feeding a large ray is a rewarding interactive experience for all those who do it. Of course, their ‘other-worldly’ appearance and their obvious beauty and character add to the pleasure. Most rays grow fast and if properly cared for will quickly grow to a size that is not suitable for a small tank . They require a large tank even at the beginning of their residency. Ideally they are kept as a single species, in other words they should be kept alone. Mixing other species can be precarious. One of the more popular tankmates are Arowanas, but if they are not matched for size with the rays then there can be problems. As a general rule of thumb when it comes to companion species ,"if a ray can fit it in its’ mouth then sooner or later it will eat it". If the Arowana is too big then it might attack the ray and will certainly beat the ray to food. On the other hand if the Arowana is not big enough then there is a good chance that eventually the ray will eat it. A friend of mine found this out the hard way when his 22" disc Tiger ray ate his 10" long $2000 red Asian Arowana. Plecos can present a similar problem, either they will be eaten by the ray or they will take free meals from the rays upper body slime coat, causing stress and possible secondary infections in the wounds and eventual death for the ray. Rays when healthy have voracious appetites and enjoy a range of foods. The easiest are live foods. California blackworms and earthworms are greedily sucked down. Ghost shrimp are a favorite food that often sends my smaller rays literally spinning with joy. Once used to it, most rays will also devour fresh frozen shrimp and other similar foods. Smelt , Salmon pieces, various shellfish and other kinds of seafood are often accepted, but some can be very messy and should be tested first or only fed just before a large water change. Rays can also be adapted to homemade recipes and prepared sinking commercial foods. Hand feeding your ray is one of the most rewarding experiences guaranteed to get a "WOW" from even the most jaded person. A ray is not inclined to sting, but can thrash about with happiness when being fed so when hand feeding it is important to be aware of where the rays tail is at all times and that the ray also be aware of you so that it won’t be startled. After a while rays can become very tame, allowing petting and actively investigating your hand for possible food. Continued on Page 22... The Shoreline Page 21 ...Continued from Page 21 Water parameters Amazonian rivers are all very soft water, with few minerals at all. Only the massive volumes of rainfall prevents the pH from falling sharply. Most of their habitat is around the pH 6.5 mark. When properly acclimated most rays can thrive in our tap water and do not require extensive chemistry to maintain them. However, they eat a lot and consequently excrete a lot so good husbandry is important in order to keep the water clean and the filters clear from sludge buildup. I recommend at least 2 water changes each week of at least 25%, using aged water. More if the tank is the least bit crowded. Rays are susceptible to organ damage from Ammonia and Nitrates poisoning so it is essential to monitor those levels and maintain them at constant zero through regular water changes and good biological filtration. Ammonia poisoning is one of the main causes of the ‘silent death’ as spoken of by Dr. Ross in his books. The damage is often done in original transit, which is often more than 36 hours in a box . A ray may take up to a couple of weeks to die from this, as it refuses food and either wastes away or dies from the internal toxins, and so it is sometimes hard to understand the linkage between shipping in bad water and the eventual death. Acclimating your new rays, tank decoration Some rays are more sensitive than others, the Paratrygon and China (small eyed) species are notoriously more difficult to keep than the Potamotrygons. Common popular species that are endemic to the Amazon are Histrix and Motoros and Reticulated. Many arrive under the catch-all name of ‘Teacup’ but this really only refers to their juvenile size and has no significance for knowing their species. These are often a first introduction to keeping rays as they are inexpensive compared to the more exotic rays. Some of those more exotic looking species, such as the Leopoldi, are very hardy and very active and aggressive in their behavior, others , like the Menchacai (Tiger) rays are thought of as being more shy, but this can be deceptive as most species are very active once they are properly acclimated and in a comfortable environment. Most people will never have to worry acclimating rays direct from import. If you are happy that the ray you are acquiring is healthy then acclimation to your tank or pool is not difficult. A few feet of airline tubing to siphon water slowly from the tank into the box/bag with your new ray are all that is needed. As the bag fills remove water until the ray is in tank water and all the original bag water has been diluted out. This takes from 30 minutes to an hour. The greater the differences in parameters between the tank water and the bag water the slower you should make the change. Once this is done remove as much of the water in the bag as possible and gently put the bag and ray into the tank and allow the ray to swim out of the bag into its new home. I keep my pools bare-bottomed but most hobbyists prefer a biotopical look and want substrate. It is important to avoid using anything sharp, such as sand that contains silicates, as this will tend to shred the rays underbody, allowing an infection to creep in, often leading to death of the ray. Estes is a brand name sand that is coated to make it smooth and is available in a variety of colors and is very suitable. The few times I have used a substrate I have chosen something to compliment my ray. For Black rays I use a black sand. Rays will tend to adjust their body color tone to blend in with their background, tending to get either noticeably lighter or darker over a period of a few days to a few weeks. Rays have relatively large brains and are one of the most intelligent of aquatic animals. A ‘dressed’ aquarium can help keep it amused, Driftwood and rocks to search around for food provides plenty of entertainment. Continued on Page 25...

Just like their relatives Sharks and marine Rays, male freshwater stingrays have claspers, one on either side of the base of the tail and slightly underneath. In sexually mature males these are easily visible from above and with immature young they can be easily seen from their underside. Females do not have claspers. When mature enough to breed rays reproduce by internal fertilization and give birth to live young after a gestation period of approximately 3 months. ‘Pups’ are usually born in litters of from 2 to 8, depending upon the age and size of the rays involved. While still not a common event in the home aquarium several stingray enthusiasts and many large public aquariums around the world are now successfully breeding many varieties. As with all animals, breeding is a biological imperative for rays that only requires enough space and plenty of good food along with reasonable aquarium conditions and good husbandry to make your pets comfortable . This also makes the aquarium more enjoyable to watch and interact with for the already entranced aquarist.

One area that has not been left behind is aquarium lighting, originally the only choice we had for the aquariums were bulky fluorescent tubes that required a separate ballast box for transforming the power source to the correct output and inevitably this lead to a bulk of wires trailing from the back of the tank. As the lighting systems evolved to meet demand from the customer, the fluorescent tubes became slimmer and more compact also giving out a greater output which still meets the requirements of most fish keepers today. There are certain set ups that still need more efficient systems that do not cost a fortune to run and emit powerful lighting for the aquarium, this is especially true in the case of the saltwater aquariums, mostly the reef aquariums where the corals are dependant on a strong light source for their health. The next major development was the MH (Metal Halide) lighting system which proved to be extremely expensive to purchase and to run as they use a large amount of watts to produce the required lighting levels, this has resulted in the latest technology being researched, the LED lighting system. LED lighting has been with us for many years, originally in the aquarium hobby, LED lights were added to the aquariums to produce lunar lighting as they cast a blue glow over the tank once the main lighting had switched off for the day, these small units use small lights in strips, often only containing 12 – 24 small bulbs for illumination. Ornaments for the aquarium can also be illuminated by small LED units but what was required was a LED unit that was as powerful as Metal Halides and cost a fraction of the price to run. These units are now available and are already starting to prove to be very popular and reliable, many reef keepers have commented on the corals opening up more and displaying brighter colours when housed underneath LED lighting units. As expected with all new technology, these units do not come cheap, they compare in purchase price to the MH units but they offer long life with the bulbs and they are a lot cheaper to run over a period of time. As more manufacturers start to sell these units, prices should drop, the competition will help with this but with all new products, a lot of money has to be invested in research and development and this has to be repaid with the initial costs of the units. Continued on Page 34... The Shoreline Page 31 JSAS is pleased to support our sister clubs! The Shoreline Page 32 Open Open The Shoreline Page 33 ...Continued from Page 31 One such supplier of the LED aquarium lighting units is OC Reef, one of their featured units is the CREE 60 watt model which houses 20 bulbs, all rated at 3 watts apiece. Each of these bulbs has a 50,000 hours working life, bear in mind that standard T5 tubes need replacing every 9 months maximum. This unit is compatible with soft and hard corals, and the unit can be controlled by means of the standard on/off switch plus it has the built in feature of being able to dim the lighting and allow you to run the blue and white LED’s separately. Digital timers are also built into the unit which can be crucial for reef aquariums as the corals and inhabitants do require a controlled daylight period everyday, more so than tropical tanks, and each unit is guaranteed for 3 years. This particular unit is rated to reach depths of 48 inches in the aquarium, that is very impressive to say the least and the bulbs are rated at 10,000K for the white bulbs. This rating will supply adequate lighting for all corals and with using the dimmer switch you can reduce the lighting for fish only set ups and tropical setups if algae become s a problem. One key point that I do like is that the LED lighting units run at cooler temperatures, this has to be a great safety feature, heat sinks and fans are built into the unit, these are placed at the rear so that they are out of view and the fan can be turned off when not required. The aesthetics of this unit includes a choice of colours, namely black, silver and white, all of the units are powder coated to eliminate corrosion. The coating is finished with an easy to clean gloss coating. As with most modern lighting units, the above LED lighting unit can be bracket mounted or it can be hung with the supplied heavy gauge wiring kit, always make sure that the unit is secured safe fully secured and that the supporting joists can take the weight of the unit. Full details on the featured unit can be found at www.ocreef.com. Advantages of using LED lighting The units run at a very low heat compared to other forms of aquarium lighting, they have built in heat sinks and fans to disperse the heat, this also has the benefit of evaporation in the aquarium being at a lower rate. The LED lighting units have the capacity to be dimmed to a level that suits you or your fish, this feature is not commonplace with other forms of lighting and makes each LED unit very versatile in their use. The units do not emit any UV radiation, MH units and T5 lighting units do emit UV radiation. The depth that the lighting can reach in the aquariums is at a higher ratio compared to other units. Cheap running costs, the bulbs run at a very low wattage but still have the same power with their illumination. Disadvantages of using LED lighting The initial outlay can be expensive; the LED lighting units are a fairly recent innovation and still are not being mass produced to the same extent as other forms of lighting. Over a period of time, the low running costs counter balance the initial cost but you still need the purchase money available when ready to buy. The units can still be hard to get hold off, most suppliers are selling their stock as fast as they receive it, this often means that you may have to pre order and be patient while the new stock is delivered.
