Gold Marble Angelfish (Freshwater Angelfish for sale)Either one Angel to an aquarium or more than 3. Angels are Cichlids and like most Cichlids, if you keep just 2 or 3 in the same aquarium, the strongest one will make the others miserable. Angels do very well in a group with 6 or more Angels in a large aquarium with at least 50-gallons of water that is at least 18" deep.
