Angelfish - Pomacanthidae

With spectacular markings, iridescent colours and incredible patterns, Angelfish are some of the most beautiful fish found on coral reefs. The larger species are especially majestic, with rich colours and an air of elegance.

They have a rounded and flattened body similar to their close relatives the Butterflyfish (Pomacentridae), but can usually be easily distinguished from their cousins by their larger size.

Juveniles can be completely different from the adults and often have even more irredescent patterns, but are very shy & tricky to spot.

Did You Know?
Angelfish and Butterflyfish are so similar they were once included in the same family.

Family variety

There are 87 species of Angelfish. All are generally a similar shape with compressed bodies and pointed heads. They can vary considerably in size, colouration and markings.

Behaviour

In most species all individuals are born female, changing to male only if circumstances allow - such as when the previous male dies. They are shy fish, favouring overhangs and other dark spots close to the protection of the reef when foraging or resting.

With competitor species, Angelfish are territorial and will defend their homes aggressively if threatened. Juveniles are particularly secretive, rarely venturing far from the safety of a crevice or hole.

Reproduction

Some species form mating pairs for life. In others, male Angelfish control and defend a territory which includes from 2 to 5 females. During seasonal mating eggs and sperm are released in to the water column. Juveniles of the larger species are beautifully patterned and very shy, often preferring reefs deeper than 15m.

Diet

Depending on the species Angelfish feed on anything from algae and coral polyps to plankton and sponges.

Defences

Angelfish fish are very wary, tending to dart undercover at the slightest sign of danger.
