Paracirrhites arcatus, commonly known as the Arc-Eye Hawkfish, is a popular choice for marine aquarium enthusiasts seeking an active and visually appealing fish. Recognisable by the distinctive arc-shaped marking around its eye, this hawkfish is a fascinating species that perches on rocks and corals, surveying its surroundings.
Care Level: Moderate. This species is hardy but requires stable water parameters and a suitable environment.
Temperament: Semi-aggressive. Paracirrhites arcatus can be territorial, especially towards similar species or smaller, more passive fish. It is best kept singly or in a large tank with ample hiding spaces.
Diet: Carnivorous. Feed a varied diet including frozen mysis shrimp, brine shrimp, and high-quality marine pellets or flakes to ensure optimal health.
Minimum Tank Size: 75 litres (20 gallons). A tank of this size or larger is recommended to provide sufficient swimming space and territories.
Lighting Requirements: Standard aquarium lighting is sufficient. No special lighting needs are required.
Water Flow: Moderate water flow mimicking natural reef conditions is ideal.
Placement: Provide plenty of live rock with crevices and perching spots. This allows the hawkfish to exhibit natural behaviours and establish territories.
Origin: Not Provided.
Maximum Size: Up to 15 cm (6 inches).
Reef Safe: With Caution. While generally safe with corals, Paracirrhites arcatus may prey on small invertebrates and should be introduced carefully into reef setups.
