I have a ten gallon tank with three inch an a half african Cichlids and a pleco in it (i have a 55 cycling for them right now i just haven't moved them yet). Anyway the thicker of the three africans bullies the others around and because of him one of the smaller ones normally hangs out at the top of the tank. When i went to work yesterday everyone was fine but when i got home the smaller one was gone. All that was left was a little white frame that the pleco was eating. What happened? Plecos eat meat?
