Creature of the Month: Pixie Hawkfish, Cirrhitichthys oxycephalus

A pretty little fish with pink splodges, the pixie hawkfish lives on reefs and in lagoons and between one and forty metres down. It likes to sit on small heads of hard corals or sometimes. They are more abundant on midshore and offshore reefs which tend to have healthier, intact coral communities. Coral cover is a good indicator of pixie hawkfish abundance.

Members of the hawkfish family have protrusible mouths which enables them to sit so still

Three Pixie hawkfish with octopus in the Red Sea

Territorial males maintain a harem of females. Courtship occurs at dusk or early night.This occurs throughout the year in the deep tropics but in sub-tropical areas, such as the northern Red Sea, only in the summer. They make a short (up to 1 m), rapid ascent and then spawn.

If male hawkfish take on too many females, one of the two largest females will change sex and take over half of the harem, mating as a male. In some species if a new male hawkfish loses a few females to other harems and is challenged by a larger male, it will revert back to mating as a female instead of wasting precious energy fighting a losing battle.

The pixie hawkfish is also known as the coral hawkfish.

Class: Actinopterygii > Order: Perciformes > Family: Cirrhitidae
