Found some nice loaches yesterday that looked like Schistura mahnerti  (or something else from the S. multifasciata group) to me.

Also there was one different looking loach in the tank that reminded me of Mesonoemacheilus guentheri.

Looking at the distribution of both fishes (and assuming both species are from the same shipment) I'm probably wrong with one (or both) ID's .

 

Most of them look like this at the moment. (Apologies for the bad picturesLaugh, but they're a bit skittish, very lively and haven't coloured up yet)

The other one.

Can anyone help me with their ID's?

Hi,

 

I would like to throw Schistura vinciguerrae and Nemacheilus subfusca in the ring.

Nice Henri! We've had fish like that first around here for some time and I've not been able to get any further info on them. I had the same thought as Thomas but have never seen the tail very red.They are feisty if it's the same fish. Keep an eye on them.

The second one looks like an m. guentheri variant to me.

This loach I bought many years ago as Schistura subfusca, but the valid name seems to be Nemacheilus subfusca.

Only looked at fishbase, not in the CONSPECTUS COBITIDUM, so names could be outdated...

 

Cheers,

Hi guys,

 

According to Conspectus Cobitidum S. subfusca is a synonym of S. scaturigina and that's a different looking fish. But there are notes that the status of some of the fishes in the synonymy with S. scaturigina should be re-examined.

 

Do you also think the second fish is Mesonoemacheilus guentheri, Thomas?

M. guentheri is a Western Ghats fish so I wonder why he's in a shipment containing fish with a very different distribution.

I would not worry about this too much, there are too opportunities for the fish from different places to be mixed up along the way. As just one example, fish that comes via Singapore may mix together imports from any Asian countries...I've seen this happening.

Yes, have seen that fishbase.org name them now as Nemacheilus instead of Mesonoemacheilus (the guentheri and the triangularis). The "Cobitidum" stays at Mesonoemacheilus. This is better I think.

Agree that Fishbase is wrong in this case and that Mesonoemacheilus is correct.

I tried to work through the S. vinciguerrae/mahnerti group of fishes recently and gave up after a while - total nightmare to id via external characters. Confused
