Grey Angelfish Facts

This easily recognizable reef fish is territorial, rarely leaving the small radius around its home area, and develops a long-term monogamous breeding relationship. It has a flat, oval black body with trailing black dorsal and anal fins (with yellow and orange margins), a yellow tail, and a yellow face with a black mouth. The juvenile is almost completely yellow, with a black spot on either side that grows slowly to cover most of its body.

Habitat – Distribution
The rock beauty is a species associated with clear, shallow reef habitats of the tropical western Atlantic Ocean. It is found from Georgia to Bermuda and the Bahamas, and from Florida to southeastern Brazil.

Diet – Behavior
Their diet consists of mainly sponges but they have been known to occasionally snack on corals, tunicates, and algae

Reproduction – Juveniles
Adults generally form long lasting, perhaps even monogamous, pairs. The pair mates by rising slowly up in the water column, bringing the bellies close together, and releasing large amounts of sperm and eggs into the water. The female can release anywhere from 25 to 75 thousand eggs each evening, and as many as ten million eggs during each spawning cycle. The eggs hatch in 15 to 20 hours after fertilization. Growth is rapid and three to four weeks after hatching, the juvenile rock beauty settles on the reef. The juveniles are very territorial but, unlike other angelfish, they do not set up cleaning stations. They are thought to feed on planktonic animals, small invertebrates, and even mucus secreted from other fish.

Conservation Status
Rock beauty angelfish are classed as Least Concern by the International Union for Conservation of Nature. They are used as part of the commercial aquarium trade.
