Several months ago, Neil Armstrong told me how
he was organising the collection and despatch
of several Victorian fish species to his
photographic mate Gunther Schmida. Gunther
was keen to re-photograph Nannoperca

Eels were also always abundant in the local waterway.
Of course as soon as he had to catch some fish for
Neil, Kwai found the Pygmy Perch had all mysteriously
vanished! Anyway, Kwai did manage to catch 3 nice
Eels, ranging from 30 to 50cm, which he dutifully
passed on to Neil. Neil then told me of his lack of
Pygmy Perch, to which it was my turn to brag to him:
“Jen and I often go riding along the Warburton bike
trail each week, and I often accidentally catch a few
australis if we stop at Woori Yallock Creek to catch
glass shrimp for fish food.”
So a couple of days later Jen and I did our usual half
hour ride to the “Woori”, I had a small “pole-net” in
the back pack for the quick collection of a few perch.

try and track down some nice specimens for him.
Not to be defeated, the next evening we drove back to
At the same time I was going to send up some the “Woori”, this time I was armed with a larger
Glossolepis maculosus to Gunther, also to be
photographed, so I suggested Neil pass on his
fish to me so that I could send them in the one
consignment.
This innocent enough suggestion set off a series
of, at times, farcical events.
Several weeks elapsed and no fish were
forthcoming, so I was beginning to wonder if
Neil’s fish had come to a nasty end. As it turned
out Neil was getting the fish from another ANGFA
member Kwai Chang-kum. Kwai works at
Werribee Zoo, which has an extensive water
feature which is supplied from the nearby
Werribee River. On many previous occasions

drought and looked “easy pickings”.

catch (of course this act brought great merriment to Jen and I
responded with a few well chosen but unprintable words!)
Then, on my 2nd or 3rd netting attempt I managed to snag the net
in a not very accessible spot, and then managed to break part of
the nets frame. By this stage Jen had decided this was obviously a
waste of time, so she went off collecting dry cowpats for our veggie
garden at home. I guess someone had to be doing something
constructive!
Feeling decidedly peeved, I persisted with the now partly useless
net, but after another 30 minutes I did not collect a single fish, plus
I managed to totally stuff the already partly stuffed net. Oh well, at
least Jen got plenty of fertiliser.
Meanwhile at the Armstrong residence, the largest Eel had managed
to eat its 2 slightly smaller brethren, and then jumped out - no
doubt in search of its next meal.
Luckily Neil found it before it was too dried out and it soon
recovered back in its aquarium.
A week later the eel was delivered to my work and was put in an
aquarium with several large pieces of terracotta on the coverglass,
to ensure no Houdini escapist acts would occur. Sure enough, the
next day one of my co-workers was walking past the tank and
nearly jumped out of his skin when out of the corner of his eye, he
thought he was about to step on this leathery looking snake. It
was, of course, Neil’s Eel, and once again when placed back in its
aquarium, it demonstrated the amazing recuperative powers of this
species.
Finally, another ANGFA member Phil Littlejohn came to the rescue
with several Pygmy Perch - I must admit that in the end I was glad
to be rid of Gunther’s fish.
And the last time I heard from Gunther the eel is still in its aquarium!

I am sorry Joe...Let me explain. Joe Emmons, TBAS president, did
everything he could to get the President's column to me this month.
As a matter of fact he was almost early and the copy of the presidents column sat on my hard drive for a week or more until the
moment hit me to put the March issue together. Well, I started to
work on the March issue and I started with Joe's column. I couldn't
load it......my computer wouldn't load it????? Now folks.....my computer will load a "peanut butter and jelly sandwich" if you talk to it
right! I tried this and that and everything and it wouldn't load! So
I contacted the guy who sent the column to me for Joe and asked
him to send it again, that there was a "read" problem and it might
have been in the e-mail process. The next day it came and I tried
again............no luck. I sent another note for him to talk with Joe and
see if they can save it in a different format. I guess he either didn't
get the e-mail or forgot........anyway I got a hold of Joe and he kindly
brought it down from Clearwater for me on Sunday afternoon to be
sure it got in this month's bulletin...........well, it didn't load!!!!! Beats
me Joe so we'll talk about it and now I am writing an article about not
getting an article.........;-).......that's computer talk for a laugh ....:-). A
"smiley" face turned to the left!
Well, Why the ANGFA push? I received an e-mail the other week
and it was from the editor of the ANGFA club offering an extra article
if we would print the article about ANGFA...........my thought was...
"Hummmmm".....he didn't even have to off the second article to get
me to print the first.....he must not have been an editor for long. I
probably would print things written on toilet paper if it had to do
with aquariums! Anyway.......thanks to the ANGFA group for the
articles and welcome to our part of the world and maybe if we are
lucky enough we will meet somewhere and share some fish. For
sure all of the Tampa folks should go to their web site and take a
look. It seems as they have something started down there.

When you think of Australian freshwater fish, do rainbowfish come
to mind? The Australian New Guinea Fishes Association (ANGFA)
was formed in 1982 as a group of hobbyists, scientists, adventurers
and conservationists from around the world dedicated to
freshwater fishes, plants and other aquatic life native to Australia
and New Guinea.
Yes, we love rainbowfish, but there’s much more to ANGFA.

Whether blind cave gudgeons, nurseryfish,
or even
lungfish, we have members with first-hand experience. Our interests
extend to other forms of aquatic life such as amphibians, insects,
crustaceans and plants. Like other areas of the world, our aquatic
life is threatened by pollution, deforestation, development and
introduction of exotic species. Surveying and documentation of
diverse native habitats is a primary objective. Many species are
yet undiscovered.
ANGFA publishes Fishes of Sahul,* a high-quality journal,
produced and published by native fishkeepers for native
fishkeepers – four issues per year. Each issue contains 24 pages
of diverse, informative and interesting original articles backed up
by spectacular, full colour, glossy plates. Once a new member
receives their first couple journals, they often want a complete set
of back issues! A small sample of recent articles:
