Hello all, I purchased two Jack Dempseys and a single Firemouth on November 1, 2010. Since then the Firemouth and one of the Jack Dempseys are growing and coloring beautifully. They eat great as well. I feed Omega One super color cichlid pellet and frozen bloodworms. The other Jack dempsey seems to have not grown. My water is fine and the other fish seem to be at perfect health. The stunted Jack will not eat pellets but he does enjoy the bloodworms. He has been stuck at this size for 2 1/2 months, any suggestions?
