Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10; Mjukstrålar i ryggfenan (totalt) : 14; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8. Forehead slopes steeply; snout somewhat pointed. Preopercular notch and knob weak. Scale rows on back parallel with lateral line. Rosy red anteriorly, becoming bright orange to yellow over most of the body; the fins are mainly yellow or orange; the inside of the mouth is white; a bluish horizontal streak runs below the eye.
Found in inshore reef areas over hard bottoms until at least 60 m depth (Ref. 9313). Tolerant to freshwaters (Ref. 36880). Form aggregations during daylight and shelter as solitary fish in caverns. Feed on fishes, shrimps, crabs and mollusks. Marketed fresh or frozen (Ref. 9313).
