I saw this guy at an LFS. Labeled as "Red Tail Zebra Loach". Any Latin name on hand? I know "classic" loaches are incompatible with snails - how about this guy?
Hard to tell with the picture but my best guess is one of the schistura loaches definitely not botia striata but most likely this guy http://www.loaches.com/species-index/schistura-mahnerti. Similar to the Shistura vinciguerrae but the headshape is different. Real way to tell the difference is the mahnerti has a pronounced suborbital flap but I don't know what that looks like lol.
It appears they prefer fast moving highly oxygenated waters so high flow river/stream style tank. Average water temps 73-79f. Territorial need for lots of hiding spaces and probably not compatible with more delicate species. Says max size 3 inches even though the ones in your picture look maybe a lil bigger already.
Doesn't mention anything about snails as a food source and it appears the mouth structure is different from botia loaches so I would guess snails ok but don't hold me to it.
Pretty cool loach imo could be a unique setup you don't see often.
Very nice find! What is the asking price? I'm not sure about the snail thing, but fishbase mentions that insect larvae were found in a specimen's stomach. I would try it with a snail you're not too attached to first...
