Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 18.0 cm TL Männchen/unbestimmt; (Ref. 48636); common length : 15.0 cm TL Männchen/unbestimmt; (Ref. 48636)
Rückenflossenstacheln (insgesamt) : 12 - 13; Rückenflossenweichstrahlen (insgesamt) : 21 - 23; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 18 - 20. Body color is yellow with cross-hatched pattern on the sides. A dark black spot is sometimes present under the spinous portion of the dorsal fin. A black bar runs across the eye. The dorsal, anal and caudal fins have a dark stripe the position of which varies with age (Ref. 4855). Snout length 2.1-2.6 in HL. Body depth 1.4-1.8 in SL (Ref. 90102).
An uncommon species found in areas of rich coral growth of lagoon and protected reef flats and seaward reefs (Ref. 9710). Often in pairs (Ref. 9710, 48636). Feed on sea anemones, polychaetes, and octocorallian and scleractinian coral polyps. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205). In captivity, this species should be fed algae stones and the so-called 'feeding stones' which are prepared by spreading the food pulp over the stone. Minimum depth reported taken from Ref. 128797.
