Our albino bristlenose does just fine with our mbuna tank....he has a little bit of nipping on his dorsal fin right now, but last night we found out that the demasoni was holding fry, released 2, and that could be where his nipping came from...he may have gotten too close to mama! He frequently stays under cover cleaning the rock formations and they really don't seem to bother him at all. Hubby has demasoni, auratus, acei, yellow labs, kenyi, powder blues, bumblebee something or another and a red something or another that is actually orange....sorry, not good with the names of his fish.
