Care

Clown Triggerfish require a spacious aquarium with plenty of room to swim and areas to hide. They can grow up to 50 centimeters (20 inches) in length, so a large tank is necessary. They are known to be aggressive, particularly towards smaller fish and invertebrates, making them best suited for a fish-only or species-specific setup.

A varied diet of meaty foods such as shrimp, squid, and fish is essential for their health. It's important to provide them with a hard-shelled food item occasionally to help wear down their ever-growing teeth.

Reproduction

In the wild, Clown Triggerfish are solitary breeders. Males prepare and guard the nesting sites where females lay their eggs. The eggs are adhesive and attach to the substrate. After spawning, the male continues to guard the eggs until they hatch. Breeding Clown Triggerfish in captivity is challenging and rarely successful due to their territorial nature and specific breeding requirements.

Habitat

Clown Triggerfish are found in tropical and subtropical waters across the Indo-Pacific region. They prefer reef environments with plenty of rocky crevices and caves for shelter. Typically, they inhabit depths ranging from 3 to 75 meters (10 to 250 feet).

Their natural range extends from the Red Sea and East Africa across to the central Pacific, including the waters around Japan, Australia, and various Pacific islands.
