Common name: Gilded triggerfish

General information

The Blue Throat Triggerfish, scientifically known as Xanthichthys auromarginatus, is a vibrant and intelligent species popular among aquarists. Recognizable by its blue chin and striking yellow margin on the tail and dorsal fin, this triggerfish adds both color and personality to a marine aquarium. Unlike some of its more aggressive relatives, the Blue Throat Triggerfish is relatively peaceful and can coexist with a variety of tank mates.

Care

Blue Throat Triggerfish require a spacious aquarium with plenty of rockwork and hiding places to feel secure. They are hardy and adaptable to various tank conditions but thrive in well-maintained systems. A varied diet of meaty foods such as shrimp, squid, and clams, supplemented with high-quality pellets, will keep them healthy and their colors vibrant. It's important to note that they have powerful jaws capable of crushing shells, so caution should be taken with invertebrates in the tank.

Reproduction

In the wild, Blue Throat Triggerfish form monogamous pairs during the breeding season. They are demersal spawners, laying eggs on the substrate which are then guarded by the male. Breeding them in captivity can be challenging due to their specific requirements and the need for a large, stable environment.

Habitat

Xanthichthys auromarginatus is found in the Indo-Pacific region, from East Africa to the central Pacific. They prefer reef environments and are often seen in lagoons and seaward reefs, typically at depths ranging from 6 to 30 meters. In the aquarium, replicating their natural habitat with a mix of open swimming space and structured hiding areas can help promote natural behaviors.
