Life Cycle
provided by Fishbase
Mouthbrooders (Ref. 240). Distinct pairing during courtship and spawning (Ref. 205).
Morphology
provided by Fishbase
Dorsal spines (total): 8; Dorsal soft rays (total): 9; Analspines: 2; Analsoft rays: 8
Trophic Strategy
provided by Fishbase
Nocturnal species which occurs inshore near reefs (Ref. 7300). Feeds on zooplankton and benthic animals (Ref. 11889, 6110). Exhibits the black gut phenomenon. In nocturnal predators, it appears to serve to conceal bioluminiscent prey in the stomach cavity (Ref. 46685).
Biology
provided by Fishbase
Common in reef flats and shallow lagoons, but hiding by day within Acropora thickets and other corals, as well as in holes and crevices and emerging at night to forage on free-swimming invertebrates (Ref. 1602). Also found in sheltered seaward slopes in 1-20 m (Ref 90102). Feeds on small fishes and benthic invertebrates (e.g. shrimps - alpheids and penaieds; isopods, copepods, crab larvae, polychaete worms); relatively close to cover, within about 1-2 m (Ref. 11890).
