MattKeymasterOk thanks Thomas.

MattKeymasterThis fish (pics by Mark) is the one identified on LOL and elsewhere as P. alternans but personally I have my doubts. The body patterning doesn’t really match the description and the caudal fin has a single black bar (supposed to be hyaline in P. alternans).
Any opinions?

Steve WaringMemberThese guys are so hard to photograph. Also the glass needs polishing.

Never seen such a pangio, anyone here?

PlaamooParticipantThat is a crazy looking fish! I’m guessing the language is Russian?

Mark DuffillParticipantI translated a fair bit of the thread (good old google lol) and someone suggests that this is pPangio kuhli and the patern variation is result of constant inbreeding

MattKeymaster…and what do you guys think it is? Part of me is thinking ‘aberrant specimen’ and the other ‘hormone-induced hybridisation’….

Mark DuffillParticipantI think the sentimental side of me wants to think they are both just a one in a million natural variation but the logic side of me says “oh dear” and that these fish are indeed the product of some sort of genetic tinkering.
Unfortunately this sort of thing is just getting more and more common and is now part of the hobby whether we like it or not, at the end of the day profits rule. I think if work isn’t done to ease the pressure on natural stocks this is all we are going to be left with and it will force the majority of us purists out of the hobby

MattKeymasterFinally got hold of that Fraser-Brunner paper and I’m now almost convinced that Pangio kuhlii isn’t in the trade and quite possibly has never been photographed. As soon as I can get my home PC working I’ll post the drawings up but basically P. kuhlii has a body patterning quite similar to P. myersi i.e. full body stripes but split vertically resulting in many thin stripes.
This is nothing at all like the ‘P. kuhlii‘ pictured in aquarium books and around the internet which appear to ALL be P. semicincta!!!
Am going to write to Mr. Kottelat to see if he can confirm or provide photos of Javanese specimens.

StefanMemberThe Russian pic does not seem to work? If anyone sitll wants to contact the owner let me know; I have eyes and ears everywhere, including Russia so I can give it a try.
*spooky*

MattKeymasterJoerg Bohlen has confirmed that P. kuhlii is not, and probably never has been, in the trade plus there exists no live photo of it. I was wrong about the Fraser-Brunner drawing though – it doesn’t resemble the fish described by Cuvier and Valenciennes at all therefore can’t be P. kuhlii.
This does however mean that all ‘P. kuhlii‘ in the hobby/freshwater-and-brackish-water-fishes literature are in fact P. semicincta which would also appear to explain the historical confusion between these two. Cool result I think!
