Graham and I went to the Cichlid Conference over the Easter weekend and that is the first thing (fishwise) that came to mind while trying to think up stuff to fill this page.

Our first port ofcall is Southern Califor nia Cichlid Association in answer to the invite in Jan/Feb issue of ·Cichlid Circu lar'. Ron Harlan has the members buzzing when he asks: 'Should Dwarf Cichlids be Cheap FishT. Lee Finley intrigues when he speaks about 'Synodontis multipuncta tus Reproduction and Maternal Mouth brooding Cichlids a Cucko Relationship?'. Our next-to-Iast port of call is sunny, humid Brisbane in response to a multi invite in September then April 'Superfish'. Some items of interest include a very dis turbing comment by Jasper Trendall 'The Distribution and Dispersal of Introduced Fish at Thumbi West Island in Lake Mala wi, Africa'. Loren Willis has us reminisc ing when she wri tes 'On Spawning the Texas Cichlid'. Bill Denton tells us all about an old new 'un 'Telmatochromis caninus'. Professor Muntz's dissertation on 'Visual Pigments of Cichlid Fishes from Lake Malawi' is intriguing. Pieter Koopman extols the virtues of 'A Cichlid for the Planted Aquarium'.

I would be extremely grateful if you could provide a "recipe" for mixing up salts used to increase water hardness. Although I would be very surprised if calcium sulphate and magnesium sul phate were not included, I do not know with what other "ingredients" or in what proportions. This would be a great help to me as I am sure it would save lots of money. Also. writing this letter has made me wonder how many members actually do mix up their own salts and how similar are their "recipes". If there are not many - or even if there are - would it not be cheaper for all of us if we ordered the "ingredients" in bulk as a club? Or should I not suggest this in fairness to our advertisers? I eagerly await your reply. Yours faithfully, Helen Clyne. Dear Helen, The stories I could tell about salt "recipes" would straighten your tubifex - or one of the recipes would. Upon my return to this mecca of soft water I set up a tank for hard water species and just guessed at the amount of hydrated magnesium sul phate (Epsom salts) that I should use to make the fish feel at home. The Governor-General and some minor dignitaries were expected for high tea so I never had a chance to check the resulting hardness for a couple-a-days. When I finally got U The (,chilO Monthly around to it I could not get a reaction with my hardness test kit (I gave up at around 1000 ppml. It took five 50 per cent water changes over a period of two months to get the hardness down to 500 ppm -oops! Like you I decided to seek more in formation. So I have prevailed upon our over-stressed Editor to find and reprint an article which was published on the subject many years ago - it should be just as relevant today. In the past some people have ex horted the use of all sorts of fancy salt cocktails - some of them horrifically expensive but plain (non-iodised) cooking salt and Epsom salts have al ways served my purposes. As for buying in bulk as a club. . . well it may be overdoing things a little - storage would be a definite prob lem. There is no reason, however. why individuals can not buy these things in quantities to suit their own needs. Our advertisers, are not going to be offended. I do not believe that anyone with a serious fish collection actually buys pH and hardness adjusting chemicals in the packages which are obviously intended for single-tank owners. _ All Aquarium & Pet Supplies P/L (Cichlidariurn) 8 Dunoon Crt, Mulgrave, Vic 3170 (off Police Road) We specialise in CICHLlDS, NATIVES, KILLIFISH.

Victoria's First and Original Cichlid Centre • '" The Clchlid Monthly 1:1 I I OSCARS - The following is the text of a letter from Professor Muntz (currently in the US) to Steve Morton, previous Editor ofTCM. • prevJRus Letter to the" Editor Dear Steve, I wonder if you would let the Victorian Cichlid Society know that the yellow Oscar lenses that they provided through the advertisement in the (TCM) magazine have finally been analysed for me at the Australian Institute of Marine Science up at Townsville. The pigments involved tum out to be mycosporine-like amino acids, which means as little to me as I feel it will to most of the members of the society! What is interesting is that the same pig ments occur in anum ber of coral reef fish es, being for example particularly concentrated in parrot fishes and wrasses, and also in the coral itself The chemicals involved are, as far as the fish are concerned, taken up in the food, and must therefore occur in freshwater lower organisms, where so far they have not been identified. The function of the chemicals in the corals is apparently to protect them against the UV in sunlight, and in fact AIMS, in collaboration with leI, is trying to develop sunscreens for human use based on them. Dr Walter Dunlap, who carried out the analyses, is very pleased with the results, and we are both very grateful to the mem bers of the society who sent in their Oscars. As ever, of course, there is a catch: we would lie more! Would there be any chance of re-running the advertisement? We would both very much appreciate it if .this were possible. With best regards from Queenie and myself, yours sincerely, W. R. A.

After a small bout of "getting togeth er", the pair will spawn on either a very large flat rock or, preferably (to them), the bottom of the tank after the male has cleared away all the gravel. At this time it is an easy task to deter mine which fish is which. The male, in most cases, will tend to eggs until they have hatched, while the female seemingly wilI ignore the whole situation.

This size can be attained in as little as a year and-a-half in the home aquarium. Even then it is usually hit and miss, and the best way still seems to be to buy and raise at least three to five all together until two pair-off on their own. Once this has fwally been accomplished woe betide any other fIshes remaining in the tank. It is best to count on at an absolute minimum 50-gallon tank for breeding - a larger one would be appreciated by the leave sufficient food for the fry. After the fry are free-swimming, they will need at least four to six feedings a day to be sure that all of the fry receive sufficient to eat. they can be started out on microworms or brine shrimp, but within a matter of a week will be able to accept dry foods and grindal worms. The main thing to remember with the fry is that they are little "garbage dispos als" and must be fed heavily in order for all to grow into the cute little guys others _ will not be able (hopefully) to resist. • III' The Cichlid Monthry I DIARY OF AN OSCAR FROM NOVEMBER 1974 WDAS NEWSLETTER I THERE. I am an Astronotus oce/ latus, or as you humans, who are simple-minded beings, prefer to call me, an Oscar. Being quite amicable by nature, except to some of those silly little fishes that have been so thoughtful'ly been put in my company (quite delectable mor sels really), I would like to tell you a little about my life. My owner is quite a nice chap, as humans go. Of course he can not compare with my big, red and handsome mate. But he is quite charming and always feeds us well (beautiful delicacies such as cray fish, beef heart, tubifex worms, and even frogs and tadpoles). For these tidbits I try to show my appreciation by showing off to his friends when he drags them in to show how I nibble his fingers, or how I let him stroke me. This I am not very fond of, but what can I do when he has been so kind to me. H There was a time, however, when I was not so popular with him. I was only a baby, about four months old, when he wandered into the shop in which I was living with my mates. Having acquired a 24-inch tank and all the accessories, he had returned to buy some "pretty little fish". Peering into various tanks, he chose a few fishes which took his fancy. Then he came to my tank. Some people insist that we are ugly, but the sight that I beheld on the other side of the glass would make even the most respectable fish a social out cast. But as the saying goes: "Fish is fish, and Humans is .......??" ... whatever it is they say about humans. Well, he came to my tank and immedi ately began to tap franticaHy on the glass. Ohhhhh - the agony. We fish darted about everywhere in an effort to escape the terrible vibrations in the water. He was CHADSTONE QUARIUM rTheCii:;nITdU~hly promptly stopped by the proprietor, thank goodness. He had chosen ns, naturally, be cause of Our beautiful color and cute ap pearance. He was later to discover the consequences of his ignorance. After a long trip in one of those horrible plastic bags, we were placed in his tank with about 15 other fishes. Too frightened to think of anything else, I fled to the safe ty ofa nearby rock. That night, after every thing was quiet, my mate and I, feeling a little peckish, started hunting for food. We found that "Funnyface" had been quite generous with food, and live food at tbat, and we had quite a feast. (For those who have never tried Guppies and Neons, believe me, they are delicious.) With full stomachs we decided to settle-down for the night.

It appeared that only we two Oscars were left and we both appreciated the p~ace and quiet. When Funnyface appeared on the scene, we sidled up to the glass, appealing for food. None appeared. Something definitely appeared to be amiss with our owner. He quickly disappeared from the room behaving most strangely. Probably just another human habit, I supposed. Twice more we were offered more of those yummy little fishes, which we in stantly consumed with relish - much to the horror of Funnyface, but we could not understand why no more were forthcom ing the next day. We had to content our selves with dry food (not very tasty, but any port in a storm as they say). The fish in the tanks on either side of us were more fortunate than ourselves, as they were fed on beef heart. As they were larger fish than us we were quite content to be by ourselves just for our well-being. That is how Funnyface started with his cichlid tank. We have since been moved from our original home to a 36-inch tank, then to a 48-inch tank, and are currently residing in a 72-incher with plenty of room to grow rapidly. We have plenty offood to appease our huge appetites, and are loved by Funnyface who provides us with the best offood and the best ofcare. _ ••••••••=-.,•• - c ..c u o 2 u ..c Q) o f ..c o c ..c - 2 "2 ..c Q) o U L r I~' The Cichlld Monthly ves Promotion Aart Langelaar I received a phone call from Kevin Mor gan, proprietor of A-OK Pet and Aquari um Centre, Mountain Gate (a member and new advertiser in TCM) enquiring if we would be interested in pushing our bar row at a shopping centre promotional event - after consulting other committee members it was agreed that we would participate. Kevin supplied two three-foot and one four-foot tank to display cichlids in the shop window. One tank contained Angels; the four-footer a large pair of Tilapia butti karen; and the other tank held a mixture ofMbuna. All the society signs were dragged out from behind the cupboard. We set up two tables with umbrellas and displayed fish calendars, car stickers, TFH, FAMA and TCM magazines. A seven-foot board was erected adver tising the society's aims and explaining our family social events. Various commit tee members - Danny Genovese, Dave Thorn, Robbie Scott et al supplied us with about 2000 "Do You Keep CichlidsT pamphlets. Kevin donated 72 tins offish food for us to hand out to the public. He also procured 4000 Parks and Environment pamphlets and organised announcements on the PA system explaining what the VCS was and stood for; and that a panel of committee members were outside shop 36 to help with fish-keeping problems (and to hand out the freebies). During the campaign more than 1000 "Do You Keep Cichlids?" and about 3000 Parks and Environment pamphlets were handed out to interested parties. Some cars stickers and TCMs were sold, but the accent was on promotion. Since the (af)fair we have been ap proached by Gillian Fitzgerald, Editor of the 'Hills Trader' to publish an article (to be extracted from the handbook) about the VCS and promoting the fish-only auction on 28th April. In my opinion, this has been the best promotion attempt since I joined the soci ety - it ran for two days. John Reeves worked the Friday and on Saturday Dave and Helyna Thorn and myself took a turn. I feel sure that the many invitations to visit our meetings will result in quite a few new members. In conclusion I would like to thank everyone for their palticipation. _ ~ I I The Cichlid Monthly , AQUARIUM PTY LTD FOR ALL YOUR AQUARIUM SUPPLIES .

'IE' 1[01 The Cichlld Monthly I I The (,child Monthly m. OSCARS By DAVIDWYMOND ,,N FROM SEPTEMBER 1977 FINCHAT EVER has a fish with so many disadvantages been as popu lar as the Oscar. A full-grown pair requires a 50-gallon aquarium, wtIl eat anything smaller than a medium-sized tuna, uproot any plant smaller than a tree, push rocks around the aquarium, splash water on the carpet and bite the hand that feeds them. How does such a bundle of obnoxiousness become so popular?" TFH, September 1968. Before I answer this question, it would be best to find out a little more back ground about our subject. Velvet Cichlid, Peacock Cichlid, Oscar - these are the common names of Astron otus ocelJatus. Astronotus because of the bright-orange spots on the side of the adult fish - ocellatus because of the ocellus or eye-spot on the caudal peduncle. The fish is originally from eastern Venezuala, the Guianas, the Amazon Basin and Para guay. It was first introduced to the Ameri can aquarist in the early 1030s. Since that time many an unsuspecting novice has fallen for the one-inch-long fish; black with yellow stripes, that presses up to the glass of the dealer's tank furious ly fanning its tail and begging for atten tion. The baby Oscar will usually thrive in a community tank on a diet of flakes, pel lets, guppies and neons. Fortunately, for the Oscar, by the time his owner realises that the fish has been supplementing its diet with a little live food, our aquarist has decided to keep it all costs. RAYONN#A'lfUM An AlternatlfJiBtihlid Centre RESERVOIR 3073"::::;:;~:··· Phone: 4786614 Astronotus oce//atus juvenile. The only reason for such an apparently stupid decision, and hcnce the secret ofthe Oscar's popularity, is personality. Your Oscars are always pleased to see you ap proaching their tank and activity increases dramatically when you reach for food, as the fish startjostIing for position below the gap in the coverglass. Oscars are gluttons and iffed too much at once, are liable to get indigestion. They will sit on the bottom of the tank taking decp gulps of water and giving an occa sional hiccup. This condition usually rec tifies itself within three to four hours. One book suggests a tablespoon of epsom salts per 10 gallons will cure your dis traught fish. The first Oscar I owned showed as much personality as any dog or cat, if not more. At times the glass of his tank would go green with algae so that you could bare ly see the fish inside, but when the glass was cleaned he would sulk for several days. No delicacies could entice him from his corner. Thc same would happen when I tidied his sand or changed the filter wool. The only thing the fish did like about me working in his tank was that it gave him a chance to get me to scratch his belly. The fish grew to almost 12 inches on a diet of pellets, garden snails and worms. Which reminds me of a story involving good mcmory on the part of the fish ... when he was about six years old I fed him a garden snail. Usually I was very careful to remove all of the snail's shell, but on this occasion part of the inside spiral re mained. Oscar got this lodged somewhere in his mouth and it took a good IO minutes of hard coughing to dislodge it. That was the last snail the fish ate. Try as I did, he would refuse point blank to ever eat another. Although the Oscar's boisterous nature includes much jumping, splashing and dashing around the tank, care should be taken not to startle or frighten him, for he is a powerful fish and can easily hurt him selfon the coverglass or sides ofthe tank. A suitable home for a pair of medium sized Oscars is a three-foot tank. Other requirements are: a light, a pump and two heaters. Two heaters are necessary because in his dashing around, an Oscar can easily break a heater tube. With two heaters your fish is safe from freezing. A safety point here is that you should always check that all heaters are intact in any tank of fishes of this size before you place your arm in, even if you are wearing rubber soles. If a heater tube is broken and you brush ":1 against the earthed light reflector you will receive a nasty shock, as I once did. (With the price of heaters these days, a more sensible solution might be to protect the heater/s with large rocks - Ed.) Filters are a problem. Large box filters are good but the fish will often give them a clout with his tail, popping the top off the box and spreading the filter material all over the tank. I overcame this problem by putting two rubber bands over the box filter to hold the top down firmly. Another problem with box filters is that when going hard enough to adeq uately filter the tank, they tend to be rather noisy. The obvious answer is a power filter, of which there are many good types on the market now. I have heard of three methods of sexing Oscars. One is described in the 'Encyclo paedia of Tropical Fish', it says: "The male has some bright-red markings on the gill-covers and near the belly region on the sides. The female is drably colored." A second was contained somewhere in one of the references I read. It claimed that the male had three dark spots located centrally just below the dorsal fin. The third was by word of mouth and was that the male's dorsal and anal fins will both brush the caudal fin as the fish swims - the females fins are shorter and will clear the caudal fin. I feel that each of these methods is open to debate and I would be interested to hear from anyone who could give me more information on sexing Oscars. Oscars spawn like many other eichlids, preferring large flat rocks on which to lay their eggs. Spawns are usually very large, numbering up to 1000. As parents, Oscars The CichlidiV!onthly I leave something to be desired. Sometimes they exercise very good parental care, but eggs and fry are also frequently eaten, es pecially ifthe parents are disturbed. There are several color varieties of Os cars available. The normal or wild type, which is basically chocolate or olive in color with some small patches of orange. The Tiger Oscar has the same basic color ation but the orange has increased in area. The Red Oscar - the finest example I have seen of this type was almost totally brilliant-red with even the fins being tinged with red. The owner said the fish had been imported from Thailand, where most of the breeding work has been done on Oscars. An interesting note on the Oscar is to be found in an article by Axelrod in the August 1974 TFH. While on an expedition to the Amazon he bought, at a local fish market, what he described as a new kind of Oscar, to quote him: "The usual Aslrono tus oceliatus has one ocellus on each side of the body. The Astronotus I found in Tefe has none, one or two spots on the caudal peduncle and from one to eight spots on the dorsal, some of which over lap. In no case did I find both sides of the same fish were marked the same. That is, the number of ocelli on caudal peduncle and dorsal varied from side to side." Finally, the Oscar is a hardy fish; easy to keep and quite adaptive. The fish is also reported to be an excellent fish for eating. So if your Oscar finally tries your patience or your wallet to the limit ... don't forget, always scale towards the head! _ .

Lonvention Raffle; I he blggt:~t 01 ItS lund ever undertaken by the YCS - resulted in a net profit of more than $2500. Convention Auction: A special fish-only auction of high-quality and rare fishes net profit more than $800. Due to its suc cess and popularity the committee has de ri<kd 10 makr I The Cichlid Monthly lhi~ fln annual rv('nl International Cichlid Conference: Held in Florida. The society was represented by means of a poster, magazines and infor mation sheets. New Handbook: A superb new handbook has been designed and printed. It will be distributed to members as soon as possible. Auction Roles: A set ofrules regarding auc tions has been drawn up. These rules will, it is hoped, overcome minor problems ex perienced in the past. This was a com bined exercise by EDAS and the YCS, and will apply to all auctions conducted by either society. Victorian Aquarium Societies: Presently, EDAS, ANGFA and the YCS are attempt ing to form a sub-committee from the three societies in order to promote closer co-existence with the possibility of one common meeting night per year and a combined exhibi tion in 1991. We all agreed that for too long a period, too much knowledge has gone unshared and this must be detrimental to the hobby in general. Pathology Service: Dr Jim Greenwood and Dr Grant Rawlins have offered their services, free of charge, to do autopsies on our fishes. To date, shamefully little use has been made ofthis generous offer. Sponsorship: Recently, TFH Australia Pty Ltd has agreed to sponsor our Annual Table Show, which during 1990 will be known as 'The YCS Wardley Table Show'. Th(',' will oonfll(' our flnnufll trophi('~ The CichlJd Monthly SUMMARY OF 1989-90 We have come to the end ofour 18th year and it is without fear ofcontradiction that I say: "It has been a very constructive and suceessful year for the society." It is my h(l~ ~('t fl standard which will be difficult to equal and even harder to better. This made my job as chairman an easy task as well as a pleasure (I always said it was the easiest job - Ed). Credit must go to the previous committee for their groundwork which resulted in some ofthis year's events, eg the Convention, the Con vention Raffle and the Fish-Only Auction. I think I speak for the society in general when I express gratitude to this committee (present and retired members) for their efforts. OUR REGULAR FUNCTIONS Table Show: Showed a slight decrease in participation. Library: Has obtained new books in excess of$300. Trading Table: Has purchased better, in trodueed new lines and magazines, and most importantly had a record year. Home Show: Had average participation and saw new judges and photographer. Mini Auctions: This is perhaps our least successful venture for a long time and could really do with your participation. Donations: We would like to thank the members who have donated and convey "JI _ ""ard I~y·sTable Show Africans and Asians Species (l~ well as our Popular Choice monthly tro phies. Furthermore, TFH Australia will take out a full-page advertisement on the back cover of'The Cichlid Monthly'. Advertising: We have mcreased our adver tisements during this year and negotia tions are nearing completion with others. Finance: See the Treasurer's Report else where in this issue. sin('('r(' h<-li('f,hat this ("ommittt'(' I I 2 3 4 5 Chilotilapia rhoadesii Chalinochomis bn'chardi Chalinochromis spp'" Labeotropheus trewavasae Pseudotropheus lombardoi Entrant Aart Langelaar Ken Whelan John McGrath Jonathan Sheilds Paul Dundas Cond Fins Shane Scales Me (.....30){mu30j(murol (mul0}{mell0) 26 22 24 28 28 26 27 24 26 27 18 16 17 18 18 6 8 8 9 9 7 7 9 8 6 Total 83 80 82 89 88 JUDGE'S COMMENTS I.

Annual Auction: A great effort which re sulted in an all-time record $896.04 in commissions and a further $100.20 from the sale of coffee/tea/soft drinks and sandwiches. Elaine Turner Memorial Art and Photo graphic Competition: An all-time record number of entries. TCM: Our magazine has maintained its high standard, however, a greater input from the members would ensure that it will retain its second-ta-none rating. Fish House Nights: This is another item which is slightly down on previous years. Participation on the part of the general membership, rather than just committee members, would remedy this. Social Secretary: Without a doubt the most arduous position on the committee (Second most arduous! - Ed). Each month we have enjoyed a great supper two small words virtually taken for grant ed, however, it was always there. The a.n nual dinner, Christmas sausage sizzle and pool party were great occasions which took a lot of organising - met with lots of different opinions but very little assistance other than the usual one or two regulars. Ladies we thank and salute you for your fine efforts. _ • I'll I The Cichlid Monthly Minutes of previous meeting The president opened the meeting at 8.01 pm and welcomed all 42 members and nine visitors present.
