In the aquarium
It is highly sought after and prized member of the Pomacanthus genus, composed of large marine angelfish. Bluering angelfish can reach up to 12 inches in the wild and often obtain lengths near that in captivity.
In the aquarium bluering angelfish are algae grazers but consume fish and coral flesh as well. They are known to eat shrimps and nibble on both large polyped stony and small polyped stony corals. Overall most seasoned reef aquarists do not recommend keeping this species in a reef aquarium due to these habits.
