Short description Morfologia | Morfometria

Spine dorsali (totale): 12; Raggi dorsali molli (totale): 14-16; Spine anali 2; Raggi anali molli: 14 - 15. Juveniles overall black with scale centers bluish; white blotch on forehead and upper sides; all fins black except the transparent pectoral and outer portion of soft dorsal rays. Geographic and behavioral color of adults variable; no spot on forehead; spot on upper sides very reduced; head and fins normally black; scales with black margins. Margins of preorbital, suborbital and preoperculum finely serrated (Ref. 2746). Nuptial fish generally paler color. Body depth 1.4-1.6 in SL (Ref. 90102).

Biologia     Glossario (es. epibenthic)

Adults inhabit coral and rocky reefs, juveniles often commensal with large sea anemones, sea urchins, or small coral heads (Ref. 4391, 48636). They occur in small to large aggregations. Stomach contents include algae, copepods, and other planktonic crustaceans (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 120737).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Courtship characterized by male 'signal-jumping'. Captive pair reported to spawn thrice monthly with a total of 17 over a 7-month period (Ref. 2856). While protogyny was originally proposed for this species, recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).
