I am gonna have to say, I don't have much of a clue with lfs names, if you hads a pic, I could possibly help. Odds are it is Venesula which gets an average of 18", but a possible 24". 125 gal. Pellets and other meaty foods. Tankmates, other large peaceful but able to hold there own cichlids. Do well with plecos, to the best of my knowlege, but Peanut Power would be the one to give you the best advice, since he is the most addicted.
