I was at one of our LFS saturday night and was checking out some of the new cichlids they had for sale, when I looked in the convict tank and seen they had mislabeled a handful of tilapia buttikoferi for convicts. So I purchased 3 of them, right now they are about 1 and a 1/2 inches long. My question is which one of my tanks could they be kept in? My Mbuna/Hap tank, or my South American tank? I know that these get quite large, so I actually only intend on keeping one of these, and trading the other two after they mature a little.
