About

Carlsons Anthias is a small and beautifully colored member of the Pseudanthias genus, prized for its vivid purple and pink coloration. Males display particularly striking hues with elongated dorsal and pelvic fin filaments that trail gracefully as they swim. Females are more subdued in color but still attractive, typically showing a soft lavender to pinkish tone. This species is found in the Western Pacific, often along outer reef slopes at moderate depths.

In the aquarium, Carlsons Anthias is a moderately hardy species that adapts reasonably well to captive conditions compared to some of its more delicate relatives. A 70-gallon tank is the minimum recommended size, providing ample swimming space in the open water column. Like all anthias, this species is a protogynous hermaphrodite and does best when kept in a small harem of one male with several females.

Feeding frequency is critical for long-term success. Carlsons Anthias have a high metabolism and require multiple feedings per day. Offer a varied diet of frozen mysis shrimp, enriched brine shrimp, and quality marine pellets. Strong water flow and excellent water quality are essential for maintaining the health and vibrant coloration of this species.

Feeding & Diet

Carnivore

Carlsons Anthias are carnivorous planktivores that feed primarily on zooplankton in the water column. In captivity, offer frozen mysis shrimp, enriched brine shrimp, cyclops, and high-quality marine pellets. Feed at least three times daily to maintain body condition and vibrant coloration.

Compatibility

Carlsons Anthias are peaceful community fish that coexist well with most reef-safe species. Males may be territorial toward each other, so only one male per group is recommended. They pair well with clownfish, wrasses, tangs, and other peaceful fish.

Breeding

Not bred in captivity

Carlsons Anthias are protogynous hermaphrodites, with all individuals starting as female. The dominant female will transform into a male if the existing male is lost. Captive breeding has not been achieved for this species due to the tiny larval size and specialized rearing requirements.
