[edit] Appearance

The fish is mostly black and white, with an elongated dorsal fin making the fish reach around 25 cm. The fish's caudal, anal and pectoral fins are most commonly bright yellow. It is very similar in appearance to the closely related Heniochus diphreutes but has a longer, and more circular shape.

A school of Heniochus acuminatus.

[edit] Behaviour

The species are social fish, and found in pairs or in shoals. They are a very passive fish, and rarely territorial. Some individuals even act as cleaners, especially when young, by removing parasites from other fish.

[edit] Diet

The pennant coralfish eats mostly plankton in the wild but are omnivorous in an aquarium setting.

[edit] Range

The pennant coralfish's natural distribution is in the Indian and Pacific oceans in reef settings, from southern Japan to Micronesia and Lord Howe Island.

[edit] Habitat

It inhabits deep, protected lagoons and channels, and the deeper parts of outer reef slopes.

[edit] Economic value

The fish is uncommonly harvested for anything other than the marine aquarium industry. It is a fish commonly sold as an alternative to the moorish idol, which are considered to be nearly impossible for most hobbyists to keep. It is fairly easy to care for when maintained in a properly-sized aquarium with peaceful tankmates.
