Common name: Titan triggerfish

General information

The Titan Triggerfish, scientifically known as Balistoides viridescens, is a large and robust species of triggerfish commonly found in tropical and subtropical waters. It is easily recognizable by its deep body, strong jawline, and distinctive coloration, which includes shades of green, blue, and yellow with dark lines that resemble a moustache above the mouth.

This species is known for its intelligence and curious nature, often investigating divers and aquarium decor. However, it can become territorial and aggressive, especially during the breeding season, making it a challenging species for community tanks.

Care

Titan Triggerfish require a large aquarium with plenty of swimming space and robust filtration due to their size and messy eating habits. They are not reef-safe as they tend to rearrange the substrate and may nip at or consume invertebrates and smaller fish. A varied diet of meaty foods, including shrimp, squid, and fish, is essential for their health.

Reproduction

In the wild, Titan Triggerfish are solitary nesters. The females are known to aggressively defend their nests against intruders. While breeding in home aquariums is rare, understanding their territorial nature is important for tank management.

Habitat

Native to the Indo-Pacific region, Titan Triggerfish are typically found on coral reefs and in lagoons at depths ranging from shallow waters to about 50 meters. They prefer areas with sandy bottoms where they can forage for food and create nesting sites.
