The average size of most Cardinalfish in captivity is two inches. These fish make great additions to a peaceful aquarium, adapting well to life in captivity. Extensive rockwork and coral decorations should be provided to enable the fish to retreat from other tankmates. These fish can be bred successfully in captivity, and the fry can be raised to adulthood with appropriate care.
