What are these? **updated with new pics 17th Sept**

Post by Emma Turner » Tue Jul 29, 2008 10:40 pm

A week ago, these tiny little loaches came in under the 'Yunnanilus cf brevis - Burmese Yunnan Loach' nametag. They don't look like typical Y. brevis to me, and they don't behave like Y. brevis either - but then these are really small (1.0-1.25" TL) and I have never seen Y. brevis at that size. I think they are some sort of Nemacheilus or Schistura though. What do you reckon?

That's my finger, for size comparison (couldn't find the ruler)

And finally a short video, showing their behaviour in the stock tank (please turn volume down):

Apologies that some of the pics are quite poor, but these are so tiny and active which made photography difficult! When you see them in the flesh (and on the vid, compared to the still pics) the stripes posterior of the dorsal fin are really obvious, compared to the markings anterior of the dorsal. Anyone like to hazard a guess at an ID? Burma is the definite country of collection.

They look very nice whatever they may be named. I swear I'm so jealous of all you folks with new loaches. I haven't seen anything other than Clown Loaches at the LFS in over 2 years. Sigh.

I am summoned!

I've looked at all the loaches from Yunnan (some of these may extend into parts of Myanmar) and they don't appear to match them.

The have a look of S. sikmaiensis (the N. putaoensis specimens), and also perhaps of a young Nemacheilus platiceps (but this is only known from Vietnam).

I don't think it is a Yunnanilus. It's hard to tell at this size but I agree with Emma that they are either a Nemacheilus (based on head shape and eye size, although this could be due to their developmental size), or a Schistura (looking at the shape of the caudal fin in the last shot).

I can't be sure when this size but they may be S. sikmaiensis, or undescribed. We shall see as they get older!!!

Very nice indeed! :D

Some of them do seem to carry the traditional Dorsal spot in which we see with the Schistura's.

I dunno Mick, the first specimen shown is stunning. I wouldn't mind getting a few and for some reason they look like the sort of loach that can be bred in the home aquarium to me? OK OK, i've officially gone crazy!

I also see some assassin snail eggs on the plant to the left on the last picture. :)

Hi,

we`ve bought a group of this little loaches a few days ago.
Ingo Seidel from Aqua Global(Berlin) identified them as Yunnanilus cruciatus, but he was not allready sure...

Cheers Markus

Interesting! The Vietnamese Yunnanilus was the one name i forgot about when chatting to Emma. The Yunnanilus cruciatus could possibly over flow into Myanmar past Thailand? Not sure but it could be something similar or a new find of Yunnanilus cruciatus in Myanmar or a new species all together. :?:

Morphology from Fishbase: Differs from all its congeners by the following combination of characters: distinct vertical bars on body; 8 branched dorsal fin rays; one pair of large papillae in median part of upper lip; lower posterior margin of opercle with 3-4 prominent indentations
