وصف مختصر مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي

الأشواك الظهرية (المجموع) : 12; الأشعة الظهرية الناعمة (المجموع) : 12 - 13; شوكة شرجية: 2; أشعه شرجية لينه: 10 - 12. Brown with a prominent black spot on the base of the pectoral fin. Fins with thin light blue or white margin.

Adults inhabit coral or rocky reefs (Ref. 9334). They aggregate in large numbers in open water above reefs and feed on zooplankton. Not strongly territorial as other damselfishes in the area. They become almost invisible in the darkness of deep water except for its brilliant post-dorsal white spot which gives the illusion of glowing in the dark. 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).
