Microspathodon chrysurus | All sizes

Microspathodon chrysurus, commonly known as the Yellowtail Damselfish, is a striking and robust species popular among marine aquarium hobbyists. Known for its vibrant colours and active behaviour, this damselfish adds dynamic movement and interest to a reef or fish-only setup.

Care Level: Moderate to advanced. While hardy, this species can be territorial and requires a well-established aquarium.

Temperament: Semi-aggressive. Microspathodon chrysurus can be territorial, especially in smaller tanks or when housed with more passive species. It is best kept with similarly sized or robust tankmates.

Diet: Omnivorous. A varied diet including high-quality marine flakes, pellets, frozen mysis shrimp, brine shrimp, and algae-based foods is recommended to maintain optimal health and vibrant colouration.

Minimum Tank Size: 120 litres (approximately 30 gallons) to provide adequate swimming space and reduce territorial aggression.

Lighting Requirements: Standard marine aquarium lighting is sufficient. No special lighting needs are required beyond what is necessary for the aquarium’s live rock and corals.

Water Flow: Moderate water flow is ideal to mimic natural reef conditions and ensure good water quality.

Placement: Provide ample hiding places using live rock formations to help reduce stress and territorial disputes. Suitable for reef aquariums but monitor interactions with more delicate species.

Origin: Not Provided.

Maximum Size: Up to 15 cm (6 inches) in length.

Reef Safe: With Caution. While generally reef compatible, Microspathodon chrysurus may nip at corals or invertebrates, especially if underfed or stressed.

Overall, Microspathodon chrysurus is a visually appealing and engaging addition to a marine aquarium, provided its territorial nature is managed with appropriate tank mates and environment.
