Common name: Beaubrummel

General information

The Yellowtail Damselfish, Stegastes flavilatus, is a small and vibrant fish that is popular among reef aquarium enthusiasts. It is known for its striking blue body and contrasting yellow tail, which adds a splash of color to any marine aquarium. This species is relatively hardy and can be a good choice for both beginner and experienced aquarists.

Care

Yellowtail Damselfish are hardy and adaptable, making them suitable for a variety of aquarium setups. They prefer a tank with plenty of live rock for hiding and territorial purposes. Aggression can be an issue, especially in smaller tanks, so it's important to monitor their behavior with tank mates. A varied diet of meaty foods, algae, and high-quality commercial foods will help maintain their health and coloration.

Reproduction

In the wild, Yellowtail Damselfish are known to be territorial and will vigorously defend their nesting sites. They are oviparous, with the male preparing and guarding the nesting site where the female will lay her eggs. The male then cares for the eggs until they hatch.

Habitat

Stegastes flavilatus is commonly found in the tropical Western Atlantic, from Florida and the Bahamas to Brazil. They inhabit coral reefs and rocky areas, typically at depths ranging from 2 to 15 meters. They are often seen in groups, and juveniles can be found in shallower seagrass beds.
