Common name: Yellowtail Bristletooth

General information

The Yellowtail Bristletooth, scientifically known as Pervagor marginalis, is a unique and somewhat rare addition to the marine aquarium. This species is part of the Monacanthidae family, which is known for its distinct file-like dorsal spines that give the family its common name, filefish. The Yellowtail Bristletooth is characterized by its elongated body, muted coloration with intricate patterns, and the striking yellow coloration of its tail fin.

Care

Caring for a Yellowtail Bristletooth requires a well-established aquarium with plenty of live rock for grazing and hiding. This species is known for its diet that primarily consists of algae, so it's important to maintain a healthy growth of macroalgae or provide sufficient vegetable-based foods. They can be shy and are best kept with non-aggressive tank mates. Due to their potential size and need for swimming space, a larger tank is recommended.

Reproduction

In the wild, filefish are known to be solitary or form pairs during the breeding season. Reproduction in the home aquarium is rare, but if conditions are right, they may lay eggs that are attached to substrates or hidden within the aquarium's rockwork.

Habitat

Pervagor marginalis is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are typically associated with coral reefs and lagoons, where they can be found at various depths, often hiding among the crevices and overhangs during the day.
