Maturity: Lm ? range ? - ? cm
Max length : 10.3 cm SL ذكر/ مختلط الجنس; (Ref. 42940)
الأشواك الظهرية (المجموع) : 14 - 17; الأشعة الظهرية الناعمة (المجموع) : 10 - 12; شوكة شرجية: 0; أشعه شرجية لينه: 8 - 10. Diagnosis: 3 lateral spots on the body (Ref. 57549). Supra-pectoral spot about 1-1.5 times the supra-anal spot (Ref. 57549) and overlapping upper lateral line (Ref. 42940). Supra-anal spot present (Ref. 42940, 57549). Spots in the rayed portion of dorsal fin yellow; anal fin black (Ref. 42940). Breeding males with wide yellow marginal band in anal fin (Ref. 42940, 57549), blue breast and a narrow black submarginal band in the dorsal fin (Ref. 57549). Caudal fin membrane yellow, in breeding males with broad bands; pectoral fin completely black; dorsal fin base length 56.3-62.45% SL; 14-20 gill rakers on the ceratobranchial (Ref. 42940).
Inhabits the sand/rock interface; territorial males construct bowers on sand slopes near rocky areas with distances between bowers approximately 2-7m; females gather in large schools, sometimes numbering more than a hundred individuals; foraging schools are about 2-3m off the bottom and feed on plankton in the water column and on benthic invertebrates; mouthbrooding females are found close to the bottom (Ref. 57549).
Life cycle and mating behavior
النضج | التكاثر | وضع البيض | بيض | الخصوبة | Larvae
Builds bowers on a sand slope near rocky area at depth of 16-25 m. Bowers are circular or oval in shape with slight depression on the center and a surrounding sand mound. These contain a stone usually at the deeper margin of the sand mound. The depression is usually deepest near the stone and spawning takes place at this deepest part.
