Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 22.2, range 16 - ? cm
Max length : 70.0 cm TL Männchen/unbestimmt; (Ref. 3198); common length : 40.0 cm TL Männchen/unbestimmt; (Ref. 3507)
Rückenflossenstacheln (insgesamt): 12; Rückenflossenweichstrahlen (insgesamt): 10; Afterflossenstacheln 3; Afterflossenweichstrahlen: 8; Wirbelzahl: 24. This species is distinguished from all its congeners by the following set of characters: body deep and becoming compressed and slender with growth; D XII,10; the first 2 dorsal-fin spines rudimentary (2 dorsal-fin spines on first dorsal pterygiophore), third dorsal-fin spine longest (1.3-1.6, mean 1.4, in 3DFS/4DFS), thirrd not reaching beyond level of origin of first soft dorsal-fin ray and not greater than head length; orbit diameter subequal to suborbital depth. Colouration: body uniform pink, silvery belly and chin; spinous dorsal fin yellowish pink, other fins are yellowish pink or pale pink; cheek and region above the eye with bluish tinge; upper jaw often with yellowish orange tinge (Ref. 124569).
Found over corals in warmer waters and rocky reefs over sandy bottoms; feeds on benthic invertebrates (Ref. 5213, 124569). Sold fresh, whole or dried in markets (Ref. 3507).
