Common name: Blue-throat trigger

General information

The Redtail Triggerfish, scientifically known as Xanthichthys mento, is a vibrant and captivating species popular among advanced aquarists. This species is distinguished by its striking coloration, featuring a deep blue body with a vivid red tail and intricate crosshatch patterns along its sides. The Redtail Triggerfish is a member of the Balistidae family and is known for its unique trigger mechanism, where the first dorsal spine can be locked into an upright position as a defense against predators.

Care

Caring for the Redtail Triggerfish requires a spacious aquarium due to its active swimming habits and potential size. A tank with plenty of rockwork and hiding places is essential to mimic their natural habitat and provide a sense of security. They are generally peaceful but can become territorial, so it's important to carefully consider tank mates. A varied diet of meaty foods, such as shrimp, squid, and clams, will keep them healthy and maintain their vibrant colors.

Reproduction

In the wild, Redtail Triggerfish form monogamous pairs during the breeding season. They are demersal spawners, laying their eggs on the substrate, which are then guarded by the male until they hatch. Reproduction in the home aquarium is rare, but providing an environment that closely resembles their natural habitat can encourage spawning behavior.

Habitat

Xanthichthys mento is found in the tropical waters of the Central Pacific, often associated with outer reef slopes and drop-offs. They prefer clear waters where they can freely swim and forage for food. In the wild, they are typically found at depths ranging from shallow coral reefs to deeper waters.
