South East Asian Seas - List of fishes

The sailfin snapper frequents sandy bottoms in the immediate vicinity of coral reefs. This usually solitary fish preys on other fish, crustaceans, and various mollusk species. It is a tropical fish occasionally targeted by fishermen.

The skin of this species secretes a toxic mucus for predators and parasites. This fish is territorial and fights involving males are common. To lay eggs, both partners embrace and rise to the surface to release their reproductive cells that will be mixed by sea currents.

The sixbar wrasse frequents shallow lagoons and offshore coral reefs. It lives in small, scattered groups and spends its days hunting small fish and foraminifera, tiny single-celled organisms. Like other wrasses, this fish changes color throughout its growth.

The moon wrasse inhabits the coral reefs of the Indo-Pacific. This species is sometimes referred to as the moon wrasse due to the shape and yellow color of their caudal fin. This wrasse primarily feeds on small invertebrates residing in the rocks and fish eggs.

The twotone tang, like its counterparts, possesses scalpels at the base of the caudal fin. In times of danger, it can extend two small blades for protection against predators. Adults of these fish typically live in groups of around twenty individuals. They gather in large schools to spawn during the breeding season. They are exclusively herbivorous and graze on algae in coral-rich areas.

These surgeonfish are exclusively herbivorous, feeding on leafy algae near the reefs. The juveniles live alone among rocks or corals at shallow depths.
