The slender grouper (''Anyperodon leucogrammicus'') is a species of marine
ray-finned fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species.
The ray-finned fishes are so called because their fins are webs of skin supported by bony or h ...

Systematics
Recent molecular analyses based on five genes show that ''Anyperodon leucogrammicus'' is included in the same clade as species of ''
Epinephelus''. Consequently, the species should be included in ''Epinephelus'' as ''Epinephelus leucogrammicus''.
Description
The slender grouper is a medium-sized fish growing to a length of about . The head occupies 40% of the total length and the mouth is large, with the lower jaw longer than the upper jaw. There are no
palatine teeth, a fact which distinguishes this species from other groupers. The basic colour is pale reddish-brown liberally dotted with orange spots which are closer together on the head. There are five pale silvery blue longitudinal lines running down either side, the lower 3 reaching the tail but the upper two breaking into irregular streaks. The dorsal fin has 11 spines and 14 to 16 soft rays. The anal fin has 3 spines and 8 to 9 soft rays.
[ Juvenile fish have vivid blue and red longitudinal stripes.][

Distribution and habitat
The slender grouper has a wide distribution in the tropical Indian and Pacific Oceans. The range extends from the east coast of Africa and the Red Sea at 32°E to southern Japan and Australia at 171°W. It is found on coral reefs and seaward reef slopes and in lagoons at depths down to or occasionally .[ and can found in Andaman Sea.

Ecology
The slender grouper is carnivorous, feeding mainly on other fish such as goatfish
The goatfishes are perciform fish of the family Mullidae. The family is also sometimes referred to as the red mullets, which also refers more narrowly to the genus '' Mullus''.

s. Juvenile slender groupers are aggressive mimics of the red-lined wrasse, '' Halichoeres biocellatus'' and the silty wrasse, '' Halichoeres purpurescens''.[ They resemble them in appearance and in behaviour which lulls a potential prey fish into a false sense of security and enables the grouper to approach it without detection.Aggressive mimicry]

Status
The slender grouper is considered of "least concern" by the IUCN Red List of Threatened Species. This is because it has a very wide range and populations do not seem to be in decline.Hong Kong
