Paddle-flap Scorpionfish

The Paddle-flap Scorpionfish is a breathtaking member of the Rhinopias genus, widely regarded as one of the most desirable and visually extraordinary fish in the marine aquarium hobby. Unlike the lacy appendages of its cousin R. aphanes, this species features broad, paddle-shaped skin flaps along its body and head that give it an otherworldly, almost alien appearance. The coloration is stunningly variable, with individuals displaying solid or mottled patterns in shades of bright red, orange, purple, pink, lavender, yellow, or white, each specimen being essentially unique.

In the wild, Rhinopias eschmeyeri is found in the Western Pacific, from Indonesia and the Philippines to Japan and Papua New Guinea. It inhabits rubble slopes, sandy bottoms, and areas near soft corals at depths of 15 to 45 meters. Like all Rhinopias, it is an ambush predator that relies on its extraordinary camouflage to remain invisible to both prey and predators, sitting motionless for extended periods before striking at passing small fish and shrimp with lightning speed. It is known to periodically shed its outer skin layer to remove algae growth and parasites.

In the aquarium, the Paddle-flap Scorpionfish is the crown jewel of any predator collection. Specimens are extremely rare and can command prices well in excess of a thousand dollars, with especially vivid color morphs fetching considerably more. Despite their exotic appearance, they are surprisingly hardy in captivity and most specimens will accept frozen foods after acclimation. They are venomous and require careful handling. A dedicated tank of 75 gallons or more with appropriate substrate and low lighting suits this species well.
