I recently added a 2.5 inch firemouth to my 40 gallon cichlid tank. It's tankmates include 2 convict cichlids, each about 1 inch. I don't believe they are a pair. He was added about 4 days ago and I have yet to see him eat. The convicts are very active when feeding and always rush to the top, yet the firemouth doesn't look interested. I have a few live plans in there that he could be eating, but I wanted to get some ideas for yall. Just did a 20 percent water change too. I've got a magnum 350 canister filter on the tank.
