Scientific name: Xanthichthys ringens (Linnaeus, 1758)

General information

The Sargassum Triggerfish, scientifically known as Xanthichthys ringens, is a vibrant and intriguing species popular among marine aquarium enthusiasts. This species is known for its distinctive body shape, with a strong dorsal spine that can be 'locked' in an upright position, a feature common to triggerfish. The Sargassum Triggerfish has a unique coloration with blue and yellow hues and characteristic ring patterns on the tail, which is the origin of its common name 'Ringtail Triggerfish'.

Care

Xanthichthys ringens requires a spacious aquarium with plenty of swimming room and rockwork to provide hiding places. They are generally hardy and adapt well to life in captivity if provided with a varied diet consisting of meaty foods such as shrimp, squid, and marine fish flesh. It is important to note that triggerfish can be aggressive, so they should be housed with other fish that can hold their own. They are not reef-safe as they may nip at or consume small invertebrates and crustaceans.

Reproduction

In the wild, Sargassum Triggerfish are known to form harems with a dominant male overseeing several females. Breeding in captivity is rare, but with the right conditions, it is possible. The male will prepare a nest where the female can lay her eggs, which he then guards and aerates until they hatch.

Habitat

The natural habitat of the Sargassum Triggerfish includes open waters and reef slopes, often associated with Sargassum beds, from which it gets its name. They are typically found in the Western Atlantic, ranging from Bermuda and the northern Gulf of Mexico to Brazil, including the Caribbean Sea.
