Balistoides viridescens

Datasheet

General Description

The Titan Triggerfish (Balistoides viridescens) belongs to the Balistidae family and is characterized by its strong jaws used for crushing rock, shells, or corals while foraging. These fish exhibit varying behaviors within and between species, making Triggerfish a challenge to keep in coral aquariums. They are known for their aggressive tendencies towards other fish, requiring ample space to minimize aggression.

Aquarium Suitability

Titan Triggerfish are not recommended for home aquariums due to their aggressive nature towards other species. They can pose a threat to smaller fishes and will prey on shrimps, crabs, and other small crustaceans. Care must be taken to prevent the fish from biting on objects like rubber and plastics commonly found in aquariums.

Demands

This species demands a larger amount of food than many other fish, necessitating a well-prepared and varied diet consisting of krill, Mysis, shrimps, crabs, mussels, small fish, octopus, snails, and algae-based foods. They also require food that helps prevent overgrown teeth, such as clams, to avoid the need for stressful teeth grinding procedures.

Care and Hardiness

Titan Triggerfish have an average hardiness level and a minimum tank size requirement of 10000 liters. They exhibit interesting personalities and behaviors, often rearranging rocks and sand in the tank. Providing ample hiding places, such as between live rocks, is essential for these fish to thrive.

Reef Suitability

These fish are deemed not reef-safe due to their tendency to disturb reef structures and consume various reef inhabitants. They require a species-specific diet that includes larger crustaceans, other invertebrates, and small crustaceans to meet their nutritional needs.

Aquarium Setup

When setting up an aquarium for Titan Triggerfish, secure rocks on the substrate to prevent them from toppling over, as the fish have a habit of rearranging decor. Ensure the tank has plenty of hiding places and space to reduce aggressive behavior.

Behaviour

Titan Triggerfish showcase a unique personality compared to other fish species, with some owners even teaching them tricks using food rewards. They are known to swirl sand to find food and may spray water from the surface, requiring caution around electrical equipment.

Feeding and Diet

A varied diet is essential for Titan Triggerfish, including fish, larger crustaceans, other invertebrates, and small crustaceans like krill and mysis. Their dietary needs should include components that aid in maintaining dental health to prevent tooth overgrowth.

Dimorphism

Information regarding dimorphism and captive reproduction of Titan Triggerfish is not provided.

Habitat and Distribution

These fish are found in the Indo-Pacific region, ranging from the Red Sea south to Delagoa Bay, Mozambique, and east to the Line and Tuamoto islands. They can be spotted as far north as southern Japan and south to New Caledonia, inhabiting various marine environments in the region.
