The Holacanthus passer, commonly known as the Passer Angelfish, is a visually impressive species prized by marine aquarium enthusiasts. This extra large specimen displays vivid blue and yellow markings, making it a standout addition to a mature reef or fish-only marine setup.
Care Level: Moderate to advanced. This species requires stable water parameters and a well-established aquarium.
Temperament: Semi-aggressive. It can be territorial, especially towards other angelfish or similar-shaped species. Careful consideration should be given when selecting tank mates.
Diet: Omnivorous. Provide a varied diet including marine algae, spirulina, mysis shrimp, and high-quality angelfish pellets to ensure optimal health and vibrant colouration.
Minimum Tank Size: At least 250 litres (approximately 65 gallons) to accommodate its active swimming behaviour and territorial nature.
Reef Safety: With Caution. While it may nip at sessile invertebrates such as corals and clam mantles, individual behaviour varies. Monitor closely if housed in reef aquaria.
Lighting and Water Flow: Standard marine aquarium lighting and moderate water flow are recommended to mimic natural habitat conditions.
Placement: Provide plenty of live rock for grazing and hiding places to reduce stress and territorial disputes.
