Redfin Anthias

The Redfin Anthias, Rabaulichthys squirei, is a rare and captivating deepwater anthias prized for its striking coloration and elegant schooling behavior. Sometimes referred to as the Squire’s Anthias, this uncommon species displays a stunning blend of fiery orange-red fins, soft lavender hues, and iridescent highlights that shimmer beautifully under reef lighting. Due to its limited availability in the aquarium trade, the Redfin Anthias is considered a true collector’s fish among advanced marine hobbyists.

Native to deeper reef slopes in the Indo-Pacific, the Redfin Anthias thrives in peaceful reef aquariums with ample swimming space, moderate flow, and numerous rock overhangs or shaded retreat areas. Like many anthias species, it adapts best when housed in stable, mature systems with excellent water quality and frequent small feedings throughout the day.

Although generally peaceful, the Redfin Anthias may become shy if kept with overly aggressive tankmates. It does particularly well in reef environments alongside other calm planktivores, fairy wrasses, gobies, and reef-safe community fish. Groups can sometimes be maintained in larger aquariums, though care should be taken to minimize territorial disputes.

The diet of the Redfin Anthias should consist of a varied selection of high-quality frozen mysis shrimp, enriched brine shrimp, copepods, and finely sized meaty marine foods. Many specimens also learn to accept premium pellets and prepared foods over time. Frequent feeding is important to maintain its vibrant coloration and long-term health.

With its rarity, graceful movement, and extraordinary coloration, the Redfin Anthias makes a breathtaking centerpiece for experienced reef aquarists seeking something truly unique and seldom seen in the hobby.
