Appearance
"Cephalopholis sexmaculata" has a body which is 2.5 to 3 times as long as it is deep using standard length.Larger fish, longer than 30 centimetres show a concave dorsal profile of the head above the eyes. It has a rounded, finely serrated preopercle although these serrations are tiny in adult fish.
The dorsal fin contains 9 spines and 14–16 soft rays while the rounded anal fin has 3 spines and 9 soft rays. The caudal fin is rounded and the tips of thepelvic fins normally fall short of the anus. There are between 49 and 54 scales in the lateral line.
The body has a background colour of orange-red, and there is a sparse scattering of small blue spots sparsely which becomes denser on the head and the dorsal, anal and caudal fins. There are also elongated blue spots and bars on the head.
The body is marked with 4 dark vertical bars, although these are sometimes very faint, along the flanks. The bars merge on the back with blackish blotches found at the base of the dorsal fin and which extend onto the fin. A further 2 smaller dark bars are found on the caudal peduncle. The gaps between these bars is sometimes rather pale and pectoral fins are orange-red in colour.
This species attains a maximum total length of 50 centimetres.

They frequently associate with the cleaner shrimp "Periclimenes elegans". It can be found at depths from 6 to 150 metres. It feeds mainly on fishes.Habitat
"Cephalopholis sexmaculata" occur on diverse coastal to outer reefs, as adults, normally along deep walls with caves which have a varied and abundant invertebrate growth of organisms like large sponges and soft corals.References:
