I recently had a tank epidemic and am in need of restocking. Currently all I have are two Bolivian rams and two angelfish in a 55 gallon tank (aprox.48in x12in x24in). I was considering getting another 2 Bolivian rams and possible giving away the two angelfish. Is there mid sized cichlid that would be compatibility with the rams? I was looking into possible something like a blue acara or firemouth cichlid.
