⚠️ Important Information — Please Read First
We want to be genuinely upfront on this one. This species is genuinely venomous, with venom glands attached to its dorsal, anal, and pelvic spines capable of delivering an extremely painful sting, comparable to a wasp sting — the source of its common name. Please exercise real caution during all tank maintenance and never handle without proper protection.
📋 The Cockatoo Waspfish, also known as the Sailfin Rogue Scorpionfish, has a genuinely distinctive laterally compressed body with a dramatic, sail-like dorsal fin running from the top of the head almost to the tail. Its colouration is genuinely highly variable, occurring in cream, brown, red, yellow, or blue, often marked with irregular spots.
Native to the Western Pacific, from Malaysia and Indonesia to Japan and Australia, this species inhabits sandy, silty, or rubble bottoms and seagrass beds at shallow depths.
This is genuinely one of the more unusual scorpionfish species available, and a real master of camouflage — it mimics a crumpled, dead leaf or drifting piece of seaweed, allowing itself to sway and drift with the current as an ambush predator waiting for small shrimp and crustaceans to pass by. We want to share a genuinely charming detail: when its dorsal fin is spread, it forms a crest resembling that of a cockatoo, giving the species its name. We want to be honest that this species is genuinely nocturnal and primarily an ambush predator of live foods, so live saltwater feeder shrimp are often needed to entice a new specimen to eat. It's considered reef safe with caution — it won't harm corals, but tank mates should be genuinely passive, similarly slow-moving species, as this species may consume small fish and shrimp, and its venomous spines can injure curious tank mates that nip at it.
