Common name: Masked triggerfish

General information

The Bridled Triggerfish, Sufflamen fraenatum, is a captivating and intelligent species known for its unique behaviors and striking appearance. It is characterized by its deep, laterally compressed body, strong dorsal spine, and distinctive coloration, which includes a dark mask across the eyes and a series of lines and spots that can vary between individuals.

In the wild, these fish are solitary and territorial, often found patrolling their reef habitat with a curious and bold demeanor. They are known for their ability to lock their dorsal spine when threatened, a defense mechanism that makes it difficult for predators to extract them from crevices.

Care

Bridled Triggerfish require a spacious aquarium with plenty of rockwork and hiding places to mimic their natural habitat. They can grow up to 30 centimeters (12 inches) in length, so a larger tank is necessary to accommodate their size and active swimming behavior. These fish are not reef-safe, as they tend to nip at corals and may harass smaller tank mates. A varied diet of meaty foods, including shrimp, squid, and fish, is essential for their health.

Reproduction

In the wild, Bridled Triggerfish exhibit fascinating reproductive behaviors. Males are known to prepare and guard nesting sites on the ocean floor, where females will lay their eggs. The male then protects the eggs until they hatch. Reproduction in the home aquarium is rare, but providing an environment with ample space and proper diet may encourage natural behaviors.

Habitat

Bridled Triggerfish are found in tropical and subtropical waters of the Indo-Pacific region. They inhabit coral reefs and rocky outcrops, often at depths ranging from 6 to 60 meters (20 to 200 feet). Their natural range extends from East Africa to the central Pacific, including the Red Sea, Hawaii, and the Great Barrier Reef.
