Pseudanthias randalli
Family: Serranidae ยท Anthias
Also known as: Randall's Fairy Bass
Randall's Anthias is a striking deep-reef species characterized by its vibrant orange body overlaid with purple-violet accents. Males are particularly colorful, displaying a rich orange to reddish body with purple markings on the face and dorsal fin, while females show a more uniform orange-pink coloration. Named after the renowned ichthyologist John E. Randall, this species is typically found on outer reef slopes and drop-offs at depths of 20 to 50 meters throughout the Indo-Pacific.
In captivity, Randall's Anthias is moderately difficult to maintain, primarily due to its preference for the cooler, more stable conditions of its deeper natural habitat. They require pristine water quality and consistent water parameters, particularly temperature stability. Like all anthias, frequent feedings are non-negotiable, with a minimum of three meals per day needed to sustain their high metabolism.
Keep Randall's Anthias in a harem of one male with three to four females. They appreciate moderate to strong water current and plenty of open swimming space in the middle water column. Rock overhangs and ledges provide welcome shelter points that mimic their natural deep-reef environment. Their peaceful nature and attractive orange-purple coloration make them a beautiful addition for experienced reef aquarists.
Randall's Anthias are planktivores feeding on zooplankton in the water column. Provide frozen mysis shrimp, enriched brine shrimp, cyclopeeze, and quality marine pellets. Feed at least three times daily to support their active metabolism.
Randall's Anthias are peaceful and well-suited to community reef aquariums. Keep one male per group. They coexist well with clownfish, tangs, wrasses, gobies, and other non-aggressive reef fish.
Check CompatibilityRandall's Anthias are protogynous hermaphrodites. Spawning occurs at dusk in the water column. Captive breeding is extremely challenging and has not been consistently achieved.
