The three- striped tiger perch ( Terapon jarbua ), also known as the bow- stripe tiger perch or grunting tiger perch , is a marine fish from the family of the grunt perch (Terapontidae) that grows in the Indo-Pacific from the east coast of Africa and the South African Cape Province to southern Japan and across the North Australian Arafura Sea to Lord Howe Island and in the Red Sea .
features
The three-lined tiger bass reaches a maximum length of 36 cm, but usually stays at 25 cm. Its body is gray-silver in color, the neck is dark yellow-green. The sides of the body shimmer weakly purple. Three or four curved, dark brown bands extend from the nape of the neck to the caudal fin, with the lowest one running to the middle of the caudal fin. These bands are more evident in young animals and fade with age. The fins are transparent, the tips of the dorsal fin are black, the caudal fin are banded in black. There is a strong sting on the gill cover , which is often slightly brass-colored. Like all grunt perch, the three-striped tiger bass can produce sounds with the help of the swim bladder .

Way of life
The three-lined tiger bass lives in loose groups at depths of 20 to 350 meters over flat sandy bottoms near river mouths and also climbs up the rivers. It feeds on smaller fish, sand-dwelling invertebrates , insects and algae. The fish spawn in the sea. The eggs are laid on stones and guarded by the male. The fast-growing fry hatch after 24 hours. They wander up the rivers.
