I think that was "the "Taiwan" thingy" Pierre mentioned.
I bought one for my tank after seiing it i TopCookie's.

I have never seen mu kuhli loaches eat a snail. But I have more empty snail shells in my tank than live ones. And after I removed a bunch of substrate, I watched one of my kuhlis hunt some thing that was too small for me to see, on the disturbed substrate.
Since I have put the sand section in, that seems to be where the greatest number of shells are (I'm not sure if this is just because I can see them more easily). But that is definitely one of, if not the kuhlis' favourite place.
They are nocturnal, so are often not considered great community fish, because they can be shy. They are scale less fish, so can be more sensitive to disease and less easy to treat. But, the kuhlis in my tank survived the period of neglect that my tank went through when wi had babies.
They have the cutest little faces.
They do best in planted tanks and like caves. They should be in a group of at least 6. IMine actually seem to prefer the gnarly bits of bogwood i have - presumably because the crevices in them are too small for all other fish.
I see mine usually only at feeding time or lights out. But I do see them a lot more now I have most of the substrate under leaf cover. They like to hang out around the edges of the sand area where there are lots of caves and overhanging bolbitus and crypts.
They are extremely fast. If ones gets spooked, I don't normally see it go, just the little cloud it leaves behind. I hope I never have reason to try and catch a healthy one. I think I'd have to dismantle my tank.
I feed mine sinking pellets. I now crush them and they seem to really enjoy (!) 'hunting' for the grains. They don't seem in the slightest bit worried by the more boisterous fiveband barbs, or even Bertie the bn plec who is known to throw his weight around.
They go absolutely mad for blood worms and come out to feed quicker when I drop the delicacy in the tank.
One thing is that I don't have shrimp. So I don't know how they'd react. I have read reports. But... I'd be surprised if they attacked the shrimp because they do tend to stick with smaller snails. I noticed a couple snails have managed to get bigger than what I consider kuhli snack size. So I might have to feed them to the birds in my garden!
Anything else you want to know?
Ps there are lots of reasons to get kuhlis apart from them seeming to eat snails.
