Pelates quadrilineatus

This fish grows to a maximum standard length of 15 cm (6 in), but a more usual length is 8 to 10 cm (3 to 4 in). The jaws are of equal length and the mouth slopes obliquely downward; the front row of teeth are large and flattened, and are tipped with brown. The body is laterally compressed and moderately deep. The dorsal fin has twelve or thirteen spines and nine to eleven soft rays. The anal fin has three spines and nine to ten soft rays. The colour is silvery with four to six dark longitudinal stripes which do not extend onto the caudal fin. There may be a dark patch behind the head and another in front of the dorsal fin. The caudal fin may be either pale or dusky.[5][3]

Pelates quadrilineatus is native to the western Indo-Pacific region. Its range extends from the eastern coast of Africa and the Red Sea to northern Australia, New Guinea and Japan. It also occurs in the eastern Mediterranean Sea, having passed through the Suez Canal as a Lessepsian migrant. It occurs on reefs in coastal waters at depths down to about 20 m (66 ft),[5] often being found in estuaries and brackish water. The juveniles also occur in seagrass meadows and among mangroves.[3]

Pelates quadrilineatus is a schooling fish and a predator, feeding on invertebrates and small fishes. When removed from the water it makes a croaking sound.[3] The male fish gives parental care to the eggs, guarding them and fanning them to keep them well oxygenated.[3]
