Bursa Triggerfish (Rhinecanthus verrucosus)

Bursa Triggerfish is an amazing triggerfish one can keep in their saltwater tank. They are hardy and easy to keep. It has an aggressive temperament and does well with other similar in nature tank mates. Found at a depth of 1 to 20 m at reef flats and lagoons. It is also a shy fish and hides among the rocks when first introduced in the tank. This triggerfish is native to the Indo-Pacific region…

Picasso Triggerfish - Rhinecanthus aculeatus

Commonly known as Picasso Triggerfish, and White-banded triggerfish, Rhinecanthus aculeatus (Tetraodontiformes - Balistidae) is a reef fish native to the Indo-Pacific, commonly found in subtidal reef flats and shallow protected lagoons.

This triggerfish is easily distinguished by its angular body, distinctive color pattern (resembling blocks of colors), fin arrangement, and characteristic dorsal spine. This forward spine on the dorsal fin lies slightly above and behind the eye. It is very strong and rigid, serving as defense adaptation. When this spine is raised, it often locks in this protective position, giving the triggerfish its name.

Due to its stunning appearance, the Picasso Triggerfish has a high commercial value for aqauriums.

Wedgetail Triggerfish - Rhinecanthus rectangulus

The Wedgetail Triggerfish, Rhinecanthus rectangulus (Tetraodontiformes - Balistidae) is a strikingly patterned reef fish found in the tropical and subtropical Indo-West Pacific.

Wedgetail Triggerfish are easily approached underwater, but once alarmed the fish typically swims into a small crevice and lodge itself there by erecting its dorsal and pelvic spines (even if the tail remains exposed, the sharp caudal spikes offer some protection). If persistently harrassed, the triggerfish will repeat a series of short grunts.
