Description

The sixline soapfish is a small grouper-relative of the family Serranidae from the Indo-Pacific. The species grows to about 30 cm and has a dark-brown body with pale longitudinal stripes; juveniles have a few stripes, older fish more. It inhabits coastal waters over coral and rock and shelters by day under ledges and in small caves. As a predator it hunts small fishes and crustaceans. Characteristic is its skin, which when disturbed secretes a bitter, soap-like toxin (grammistin) that deters predators; for this reason the species is not eaten. When handled it is harmless to humans.
