Family: Serranidae ยท Anthias
Also known as: Yellowstriped Fairy Basslet, Purple Anthias
The Purple Queen Anthias is widely considered one of the most beautiful anthias species and simultaneously one of the most difficult to maintain in captivity. Males display an absolutely vivid purple body with bright yellow streaks along the face and operculum, creating a breathtaking contrast that makes them one of the most photographed reef fish in the hobby. Females are a somewhat less intense purple-lavender with yellow accents. The sheer vibrancy of their coloration is unmatched by most other anthias species.
Unfortunately, this species' beauty is matched by its notorious difficulty in captivity. Purple Queen Anthias have an extremely high metabolism and are reluctant to accept prepared foods, often refusing everything except live foods for extended periods after collection. Many specimens slowly waste away in captivity despite the best efforts of their keepers. Success with this species typically requires a mature, stable reef system with excellent water quality, an abundance of natural zooplankton, and an unwavering commitment to multiple daily feedings.
For those willing to accept the challenge, Purple Queen Anthias should be kept in a harem of one male with three to five females. They prefer moderate water flow and plenty of open swimming space. Subdued lighting or shaded areas help reduce stress. This species is best reserved for expert-level aquarists who have successfully maintained other difficult anthias species and have the systems and dedication to meet their demanding requirements.
Purple Queen Anthias are obligate planktivores with extremely high metabolic demands. Offer live and frozen mysis shrimp, enriched brine shrimp, cyclopeeze, copepods, and other fine planktonic foods. Feed at least four to five times daily. Many specimens refuse prepared foods initially and require patient weaning.
Purple Queen Anthias are very peaceful but timid. They should only be housed with calm, non-aggressive tankmates that will not outcompete them for food. Avoid aggressive feeders and boisterous species.
Check CompatibilityPurple Queen Anthias are protogynous hermaphrodites. Given the extreme difficulty of simply maintaining this species, captive breeding has not been achieved. Larvae are tiny and pelagic with highly specialized feeding requirements.
