Have You seen THAT: http://www.aquarium-glaser.de/en/news.php?news_id=1565 ?
What a stunning loach! Some say that it can be Y. lecontei. I'm not pretty sure. Yep - the stripes can suggest lecontei - but they usually have a greenish-greyish shade of it. Those have a golden shade! Only here, on photo no.4 we can see something similar to those mysterious loaches: http://ffish.asia/?p=none&o=ss&id=647
Of course stripes can suggest also skunks or Y. longidorsalis (maybe it can be this rare species?).
Generally for me the front part of their body is too massive to be a typical lecontei - it's just more similar to skunks.
From the other hand the golden shine looks like as straightly taken out from Y. splendida

It's a pity that we'll probably lose an opportunity to follow a growth of those loaches (as it was with laos tigers)

Greek!
