Belongs to the Family Cobitidae (which includes loaches). In rare occasions you may see the Coolie loach swimming up and down before it disappears again for long periods of time (even months). A very peaceful fish will do well in all tanks and will stay hidden all day long. Will come out to feed at night therefore one should remember to drop some sinking pellets every other night. Will adapt to the water parameters of an mbuna tank if the changes are gradual. Grows (very slowly) to about 12 cm and the color pattern and intensity is not lost as it grows. I had them in the tank long ago and it was not possible to remove then without taking out everything from the tank. Fortunately, the fish adapted very well and you may see one or two of them (there were four of them initially and I don't know how many are still there) getting out of their caves and swim for an hour or so before hiding again. Africans will not harass or bully it - strange for Africans. A densely planted region in the tank and plain sand in the bottom are required for this fish to feel comfortable. The photo is not the best possible because the coolie loach will not stand still for a second and may hide any minute.
