Dorsal spines (total): 8-8; Dorsal soft rays (total): 9-10; Anal spines: 2-2; Anal soft rays: 11-12. Description: A species of the pomacentrid genus Chrysiptera with the following combination of characters: dorsal rays XIII, 10 (rarely 9); anal rays II,11 (rarely 10); pectoral rays usually 14 (occasionally 13 or 15) ; gill rakers on first branchial arch 6-8 + 14-17 (usually 7 + 16), total rakers 22-24; tubed lateral line scales 11-15 (usually 12-14); colour in life brilliant blue except abruptly yellow behind vertical line extending from last dorsal spines to about anterior half of anal fin; pelvic fins usually yellow with narrow blue anterior margin (rarely with one-half to two-thirds of fin blue) (Ref. 84037). Body depth 1.9-2.2 in SL (Ref. 90102). |
| Adults inhabit sheltered fringing reefs, usually in bays at depths between about 3-20 m. They usually occur in small aggregations and is closely associated with branching formations of live coral, particularly Acropora spp. and the pocilloporid Seriatopora hystrix. This species hover a short distance above the substratum, presumably feeding on zooplankton (Ref. 84037). 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). |
