So I bought this fish at walmart because I felt sorry for it. It had been there for at least a month. I was wondering if anyone might have an idea what it might be. I have a mbuna tank with 4 red metriaclima estherae , 4 metriaclima crabro, 3 metriaclima kenyi, 1 pseudotropheus demosoni and 2 pseudotropheus socolofi.
