Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 18.0 cm TL Männchen/unbestimmt; (Ref. 48636)
Rückenflossenstacheln (insgesamt) : 5; Rückenflossenweichstrahlen (insgesamt) : 21 - 22; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 17 - 18. Indian Ocean form shows lined versus barred pattern (Ref. 48636). Spinous portion of dorsal fin black at base, deep red distally. A longitudinal row of black spots 8 or 9 subquadrangular red to dark brown spots along back alternating with similar but more vertically elongate red spots on lower side. Two narrow bright red bars at pectoral-fin base (Ref 42740).
Benthic (Ref. 58302). Usually on open sand and rubble substrates near reefs (Ref. 48636, 58302). Adults occur on deep seaward and coastal slopes and deep sand flats (Ref. 48636) at depths to 170 m and rises up to about 15 m to feed (Ref. 90102). Adults have lyre-tail and may swim high above the substrate to feed on zooplankton, usually amongst other fishes such as basslets (Ref. 48636). Minimum depth of 9 m reported from Ref. 30874.
