raider this fish is not reef compatible, and grows up to 14" long hear is a write up on it
"The Flying Gurnard is also known as the Oriental Helmut Gurnard. It is a light-brown color with orange to dark-brown spots. The pectoral fins can be flared out into an impressive display of fan-like wings, with spines extending beyond the flesh at the tips. The tips of the wings are tinged with a blue.
A 180 gallon or larger aquarium with a large unobstructed swimming area and a sandy bottom without much rockwork will provide a suitable environment. Aggressive tank mates should be avoided as well as bottom dwellers.
The diet of the Flying Gurnard consists of small bottom-dwelling fish, black worms, shrimp (mysid or brine), and other meaty foods." from Live Aquaria
