Rhinopias aphanes
Family: Scorpaenidae ยท Scorpionfish
Also known as: Lacy Rhinopias, Merlet's Scorpionfish, Lacey Scorpionfish
The Lacy Scorpionfish is one of the rarest and most coveted marine fish in the aquarium hobby, belonging to the legendary Rhinopias genus that represents the pinnacle of scorpionfish collecting. This extraordinary species features deeply incised, lace-like skin appendages covering its entire body, creating an appearance that resembles a piece of tattered, ornate fabric draped over a fish-shaped frame. The coloration ranges from deep purple and lavender to red, pink, yellow, and white, with each individual displaying a unique pattern and hue.
In the wild, Rhinopias aphanes is found exclusively in the Western Pacific, primarily around Papua New Guinea and the Coral Sea region of Australia. It inhabits rubble slopes and soft coral areas at depths of 10 to 40 meters, where its elaborate skin appendages and variable coloration provide superb camouflage among algae, soft corals, and sponge-encrusted rubble. Like other scorpionfish, it is a sit-and-wait ambush predator, remaining motionless until small fish or shrimp venture within striking range.
In the aquarium, the Lacy Scorpionfish is the ultimate trophy fish for dedicated predator-fish enthusiasts. Specimens are exceptionally rare in the trade and command prices of several thousand dollars when available. Despite the price, they are surprisingly adaptable to captive life, readily accepting frozen foods once acclimated. They are venomous, and their spines should be treated with great respect. A dedicated species tank or predator community of 75 gallons or more is appropriate for this compact but spectacular scorpionfish.
Lacy Scorpionfish are ambush predators that feed on small fish and crustaceans in the wild. In captivity, offer frozen silversides, whole krill, ghost shrimp, and chopped seafood presented with feeding tongs. Many specimens accept frozen foods after brief acclimation. Feed every two to three days. Enriched foods help maintain the vibrant coloration.
Despite its predatory nature, the Lacy Scorpionfish is peaceful toward fish too large to eat. It can be kept with other scorpionfish, lionfish, and appropriately sized non-aggressive species. Avoid all small fish and invertebrates, which will be consumed. Its slow, sedentary nature means it should not be housed with aggressive fish that may bully or outcompete it for food.
Check CompatibilityLacy Scorpionfish have not been bred in captivity. Like other Rhinopias species, they produce a buoyant gelatinous egg mass. The extreme rarity and cost of specimens makes obtaining breeding pairs virtually impossible for hobbyists. No captive breeding protocols exist for this genus.
