Hi All,

This fish was collected about 5 months back along with Schistura semiarmatus, Schistura kodaguensis & Schistura nilgiriensis.

But this is the one and only specimen that has stayed very small and very different compared to the other three fish. The S. kodaguensis have stayed small, the S. semiarmatus & The S. nilgiriensis have grown much larger.

This fish has maxed out at 1.5inch.

Looks like a member of the Aborichthys genus to me, not A. elongatus like my survivor from the group I bought last summer, but perhaps sp. "AR02"?

Hi,

no Aborichthys, compare the caudale. Aborichthys never have an indented tailfin. I bet on a Schistura, no more precisely from my side /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Cheers

Too many body bars for S. nadogiensis so...no idea. Do you know Nik?

I have had one of those Nik, unfortunately I lost it a while a go, it came in as a contaminent with a shipment of Indian Schistura.

It was over 3" when I lost it, and a very placid fish fish but I never did manage to get a definate ID.

There are soooo many schistura/nemacheilus that look like this. I don't know anybody can tell them apart.

In some cases it's possible to narrow any guesswork down slightly when the collection area is known though. There aren't so many Schistura species described from the Western Ghats - have a look at the species key in the appendix of that paper I linked to Jim.

Can't be a Nemacheilus because it has an adipose crest on the caudal peduncle if I remember right?

Hi Guys,

No have no clue on the ID of these fish. I have collected two similar species including this in different river one west flowing and the other east flowing.

This particular fish was collected in the Kodagu District of Karnataka also called Coorg. The S. kodaguensis was collected along with this fish.

The second occurrence was from the Chickmaglur District. These fish were collected from a relatively small stream living along with S. semiarmatus and one very deep orange coloured version of S. semiarmatus. Its a shame I lost all the fish so no pics of them.

Thanks for the help.

Hi Nikhil, would the orange Semiarmatus have been an alpha male ?

Hi Andy,

My guess is as good as yours. I have collected about 1000 of the S. semiarmatus till now and have never seen that colour among any fish from all the nine locations I have found them. The best colouration is from the adults who are dark green almost with the tail and some of the last few stripes orange in colour. But never a fish that was almost devoid of stripes and a deep orange. I guess my next trip could reveal something but thats a month away as heavy rains are here to stay for the next 15 days atleast.

Ooooooh Nikhil I'm looking forward to your next trip /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" /> when you go on a trip after the rains can you find that the fauna has completely changed ? replaced by different fauna ?

Andy I would say its a possibility that I might find additional species. After all in a river on a 4-6 KM stretch we found different fish at different places. For example the Glyptos were found only in the most treacherous rapids. The N. shimogensis adults were limited in large number to the deeper portions and the baby N. shimogensis and N. anguilla were in the shallower water in thousands. But they do not ship well so we do not catch any of the fish below 1.5inch and the same with large fish.

But yes there is a chance of the fauna from the higher waters being washed down to the lower bits and I wont mind a surprise at all /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> .

An aberrant leucistic specimen perhaps?

Could be Matt. My thought was more on a breeding colouration. As most of the fish seemed to be breeding I thought it might have been a breeding colouration. But I guess till the time I do not catch it again their will be no chance.
