Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 23.0 cm TL mannelijk / geslacht onbekend; (Ref. 9710); common length : 15.0 cm TL mannelijk / geslacht onbekend; (Ref. 5450)
Dorsale stekels (totaal) : 13; Dorsale zachte stralen (totaal) : 23 - 25; Anale stekels: 3; Anale zachte stralen: 19 - 22. This species is distinguished by the following characters: snout length 2.5-3.2 in head length; greatest body depth 1.5-1.7 in SL. Body pattern chevron with narrow lines on side; black band across posterior body which does not include entire rear part of dorsal fin (Ref. 90102).
Adults are found in reef flats, lagoon and seaward reefs and sometimes in turbid waters subject to freshwater runoff swimming in pairs. They are omnivorous, feeding on algae, coral polyps, crustaceans and worms (Ref. 5503). They are oviparous (Ref. 205) and monogamous (Ref. 52884). Stable monogamous pairs with both pair members jointly defending a feeding territory against other pairs (Ref. 58331) occur, but often accompany other species without being aggressive. They are easily maintained in tanks. Minimum depth reported taken from Ref. 128797.
Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Distinct pairing (Ref. 205). Stable monogamous pairs with both pair members jointly defending a feeding territory. Pelagic larvae settle to shallow (<4 m) back reef habitats consisting of rubble, seagrass and low coral cover (Ref. 58331). Monogamous mating is observed as both obligate and social (Ref. 52884).
