Pseudanthias ventralis
Family: Serranidae ยท Anthias
Also known as: Longfin Anthias, Ventralis Fairy Bass
The Ventralis Anthias is a stunning deep-water species that has become one of the most sought-after anthias among serious collectors. Males display a mesmerizing combination of deep purple to reddish-violet body coloration with elongated ventral fins that give the species its name. Females are a softer lavender-pink with less dramatic finnage. Typically found at depths exceeding 50 meters on steep outer reef walls in the Pacific, this is truly a deep-water specialist that commands premium prices in the aquarium trade.
Maintaining Ventralis Anthias in captivity is a significant challenge that should only be attempted by advanced aquarists. Their deep-water origin means they are adapted to cooler temperatures, lower light levels, and extremely stable water conditions. The transition to aquarium life is stressful, and many specimens struggle to acclimate. Those that do adapt still require meticulous attention to water quality and an unwavering commitment to multiple daily feedings of appropriate planktonic foods.
Keep Ventralis Anthias in small groups of one male with two to three females in a tank with cooler water temperatures, subdued lighting, and strong water flow. Shaded overhangs and rock ledges provide essential retreats. An automatic feeder dispensing enriched foods throughout the day is absolutely essential. While the challenges are substantial, a thriving group of Ventralis Anthias is among the most breathtaking sights in the reef aquarium hobby.
Ventralis Anthias are obligate planktivores with demanding feeding requirements. Provide frozen mysis shrimp, enriched brine shrimp, cyclopeeze, live copepods, and other fine planktonic foods. Feed at least four times daily. May initially refuse prepared foods.
Ventralis Anthias are extremely peaceful and shy. House only with calm, non-aggressive tankmates. Their cooler temperature requirements may limit compatible species. Avoid any aggressive or fast-feeding fish.
Check CompatibilityVentralis Anthias are protogynous hermaphrodites. Captive breeding has not been achieved for this challenging deep-water species. The extreme difficulty of basic husbandry makes breeding prospects very remote.
