Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 14.0 cm SL Männchen/unbestimmt; (Ref. 7247)
Rückenflossenstacheln (insgesamt) : 13; Rückenflossenweichstrahlen (insgesamt) : 14 - 15; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 13 - 14.
Adults inhabit outer coral or rocky reefs. They usually form large aggregations in shallow waters e.g. in lagoons; feeding well above the bottom on zooplankton (Ref. 2334). Diurnal species (Ref. 54980; 113699). 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).
