Dorsal spines: 7; Dorsal rays: 9; Anal spines: 2; Anal rays: 8.

Small, semi-transparent cardinal fish. Mouth subterminal. Anterior nostril closer to upper lip than to posterior nostril; skin flap forming dorsal edge of 
first supraorbital pore ending laterally with a small notch reaching up to middle of base of anterior nostril tube. Preopercle ridge smooth; posterior 
preopercle edge serrate, the angle and ventral part poorly ossified crenulate and membranous.

Colour. Semi-transparent, reddish-pink. Usually with dark-edged scales on predorsal area, between dorsal fins and lateral line, and on upper part
of caudal peduncle. A diffuse dusky stripe along middle of caudal peduncle, usually more distinct posteriorly. In juveniles the stripe is black, very 
distinct and extends to tip of mid-caudal rays. The stripe becomes diffuse with growth, frequently receding to anterior part of mid-caudal rays 
in larger fish. Usually has blackish dots at tips of rays of second dorsal, anal, caudal and, more rarely, pelvic fins. Peritoneum with small blackish 
spots overlaid with scattered larger ones; intestine pale.

under rocks or in deep holes by day. Mouthbrooders. Distinct pairing during courtship and spawning.

Global population has yet to be evaluated by IUCN, but Persian Gulf RedList assessment classified the species as Least Concern (LC). 
Very similar in appearance to A. crassipes which has also been recorded in Seychelles (Randall 1998). Hard to distinguish A. coccineus and A. crassipes 
just by photograhs. The indiviudal photographed here, however, was recorded at a depth of 10 m which is significantly outside the documented depth range 
of  A. crassiceps.
