Streaked Spinefoot, Siganus javus

The streaked spinefoot is native to the Indo-Pacific, living around coral reefs in shallow brackish (salty) waters. The range of this species is widely dispersed throughout the region with most of the population occupying the coastal waters from northern Australia to southern Japan, and from eastern Africa to New Guinea.

The streaked spinefoot is bronze in color, clear pectoral fins, with a white belly and pelvic fins. The dorsal, anal and pelvic fins have spines that contain venom which can be very painful to humans if stung. The average adult length is 12 inches but can grow up to 20 inches and the average weight is 1 pound.

This species feeds exclusively on algae attached to rocks, coral, and other standing structures on the sea bottom and also will feed on algae fragments dislodged and floating in the water. When not feeding, the streaked spinefoot will rest mid-water.

The streaked spinefoot is in the family of rabbitfish, some are used as food and others are kept in aquariums. Caution must be taken when handling this species to avoid being stung by the spines.
