Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Found usually in open rocky areas but retreats to crevices or holes or hides among spines of sea urchins when threatened. Territorial. Sits on exposed rock surfaces near a hole or crevice. Feeds mainly on small crustaceans. Oviparous (Ref. 56079). Males guard the eggs which are found attached to the walls of brood chamber (Ref. 56079). Female deposits oblong eggs in empty shells; male guards them. Often found with Lythrypnus zebra.

Oviparous, demersal spawner (Ref. 101194). Both male and female spawn with many individuals in small contiguous territories (Ref. 240). Males guard the eggs which are found attached to the walls of brood chamber (Ref. 56079). Simultaneous hermaphrodite with varying allocation of reproductive tissue to male and female function (Ref. 31569). Bi-directional sex change has been confirmed for this species (Ref. 103751).
