Amblyglyphidodon aureus is a popular damselfish species prized for its bright golden-yellow colouring and lively behaviour. This species is well-suited to marine aquarium setups, offering both visual appeal and relative hardiness for intermediate aquarists.
Care Level: Moderate. This fish adapts well to captive conditions but benefits from stable water parameters and a well-maintained environment.
Temperament: Semi-aggressive. While generally peaceful, Amblyglyphidodon aureus can display territorial behaviour, especially in smaller tanks or when kept with similarly sized or aggressive species.
Diet: Omnivorous. Provide a varied diet including high-quality marine flakes, pellets, frozen mysis shrimp, brine shrimp, and marine algae to ensure optimal health and vibrant colouration.
Minimum Tank Size: 75 litres (20 gallons). A minimum tank size of 75 litres is recommended to provide adequate swimming space and reduce territorial disputes.
Compatibility: Compatible with a range of peaceful to semi-aggressive marine fish. Avoid housing with overly aggressive species or very small, timid fish that may be stressed.
Reef Safety: With Caution. While generally reef safe, some individuals may nip at soft corals or clam mantles, so monitor behaviour closely in reef setups.
Origin: Not Provided.
Maximum Size: Approximately 10 cm (4 inches).
Lighting Requirements: Standard marine aquarium lighting is sufficient.
Water Flow: Moderate water flow is ideal to mimic natural reef conditions.
Placement: Mid to upper levels of the aquarium where it can establish territory and swim freely.
Overall, Amblyglyphidodon aureus is a striking and engaging damselfish that adds colour and activity to marine tanks. Providing a balanced diet, appropriate tank mates, and stable water conditions will ensure a healthy and vibrant specimen.
