Hey guys! Can I put an angel fish about 5 in big in a tank with a large oscar and a firemouth cichlid and a few other cichlids ..?.. I'm nervous, would hate to lose my angel fish because he's grown so large..
An angelfish is about the biggest cichlid that should be in a 55 gallon. From what you've described the angelfish might be safe from the other fish if only based on the fact it the fish will be too cramped in to actually attack each other.
