Cherubfish, or pygmy angelfish (Centropyge argi)

Cherubfish

The cherubfish, or pygmy angelfish (Centropyge argi) is a gentle omnivorous marine angelfish, with a metallic blue body and yellow to orange colouration in parts of the head only. It is native to the Caribbean and Gulf of Mexico, and has a maximum length of 8 cm. It is easily confused with the orangeback angelfish (Centropyge acanthops), but in the latter the orange stripe extends across the back.

When kept in an aquarium, cherubfish are distributed throughout the tank. They prefer reef tanks to fish only tanks. But like other angel fish, they are not completely 100% reef-safe. Results vary among individual fish and tank qualities (size, feeding, tankmates, etc.). In summary, be cautious when adding this fish to a coral tank!
