I have a red-tailed sand loach, and it does look very similar to this. Mine is in a fairly small tank, so I do not have a group of them. I also have a sumo loach and three of the "hillstream loaches/ butterfly plecos" in that tank, and they all seem to get along pretty well. There are a lot of rocks and stuff to break up the lines of vision, but they actually seem to hang out in the same areas together quite a lot.
