Bimaculatus Anthias description

The Bimaculatus Anthias exhibits color variations between the male and female individuals with the male having a pink head that brightens to a vibrant red as it runs to the tail. It also has one or two spots (just as the name implies) on the dorsal fins.

The males also have irregular pink bars that run horizontally through the body. The females display a pink body with yellow dorsal, anal and caudal fins.

The Bimaculatus Anthias just as most Anthias species are hermaphrodites with the largest and dominant female of the group often morphing into a male in the absence of males.

Pseudanthias bimaculatus

Setting up the best tank for the Bimaculatus Anthias would require a well filtered minimum 125 gallon / 473.2 litres that is set up within the standard requirement of a saltwater tank.

As middle dwellers, Bimaculatus Anthias do not require a specific substrate but tend to enjoy an environment with lots of hiding places.

Bimaculatus Anthias are good reef dwellers, and can be kept in a fish only, invertebrate or reef aquarium.

Bimaculatus Anthias feeding

Bimaculatus Anthias are carnivores with high planktivorous appetite. They can be fed with meaty foods including live and frozen mysis shrimp, enriched frozen brine shrimp. An attached refugium that ensures the cultivation of copepods and amphipods will also provide these species with nutritious live foods.

With time they will accept high-quality flaked foods, but should be offered in small quantities throughout the day.
