Randall’s Anthias in the ideal aquarium

Randall's Anthias (Pseudanthias randalli)

Setting up the ideal aquarium for the Randall’s Anthias will require a well filtered species-specific tank with a minimum of 70 gallons/265 litres or best 125 gallons/473.2 litres to house a few other individuals.

The males are preferably kept alone with several females or they are simply kept individually. Randall’s Anthias are reef compatible and can be kept with similar peaceful species.

They are bottom dwellers and enjoy an environment with lots of hiding places and low lighting.

Randall’s Anthias feeding

The Randall’s Anthias are always in their best performance when they are fed enriched frozen brine shrimp, varying diet of frozen mysis shrimp when they are introduced into the aquarium. With time they can get used to flaked meals and should be fed with high quality flake foods.

The foods should be offered in small quantities throughout the day.
An attached refugium that cultivates copepods and amphipods is required to provide them with a steady supply of nutritious live food to keep them alive and active.
