Squareback anthias Care Guide

The Squareback anthias, originating from the Western Pacific Ocean, is a visually stunning and very vibrant addition to a marine aquarium. Known for its magnificent coloration, it offers an eye-catching presence with a vibrancy rated at the highest level. Despite its beauty, caring for this species comes with its challenges, demanding a more experienced aquarist’s attention.

Tank Setup

To ensure the Squareback anthias thrives, aim to maintain a water temperature between 23°C and 28°C. The pH level should be stabilized between 8.1 and 8.4. It is critical to provide ample space, with a minimum of 100 liters per fish, to accommodate their highly territorial nature. Setting up the aquarium with plenty of hiding spots using live rock will help mitigate territorial disputes and create a suitable environment.

Feeding

Squareback anthias have a moderately demanding feeding routine. They require a diverse diet that encompasses high-quality frozen foods, such as mysis shrimp and brine shrimp, alongside live foods. Due to their active nature, aim to feed them small amounts multiple times a day to mimic their natural feeding behavior. Consistent feeding schedules will help maintain their vibrant coloration and overall health.

Compatibility and Behaviour

The Squareback anthias exhibits highly territorial behavior; thus, it’s best kept with fish that are non-aggressive and can coexist peacefully. While they themselves may show aggression towards other similar species, especially in smaller tanks, providing plenty of space and visual breaks with decor can aid in reducing territorial disputes.

Care Level and Maintenance

With a difficulty rating marked as difficult, prospective keepers need to have prior experience in maintaining saltwater aquariums. The Squareback anthias has moderate hardiness, meaning while it can adapt to stable conditions, fluctuations in water parameters can be detrimental to its health. Regular water changes, along with equipment like protein skimmers and a reliable filtration system, will help maintain water quality.

Additional Considerations

While not the most affordable species, categorized under moderate affordability, the Squareback anthias is best purchased by those ready to cater to its specific needs. It is crucial for aspiring owner to ensure they have the time and resources to meet the care expectations of this somewhat rare species. Fortunately, it currently holds a conservation status of ‘Least Concern,’ so while proper care directives should be followed, keeping them does not pose a risk to their natural populations.
