The Twostick Stingfish (Inimicus filamentosus) is a fascinating bottom-dwelling specimen prized by experienced aquarists. This venomous fish features distinctive elongated pectoral fins that resemble delicate tentacles, creating an otherworldly appearance as it glides across the substrate. 

With a peaceful temperament, this intermediate to advanced care fish thrives in well-established reef systems with plenty of hiding spots and sandy areas for hunting. Its venomous spines require careful handling and tank placement away from aggressive species. 

Best suited for aquariums of 30–50 gallons minimum, the Twostick Stingfish reaches approximately 4–6 inches at maturity. Feed live or frozen small crustaceans and fish. Reef compatible with caution—may consume small ornamental shrimp and fish. This specimen demands stable water parameters, low to moderate lighting, and minimal water movement to replicate its natural deep-reef habitat.

A truly rewarding addition for dedicated marine keepers seeking something unique and captivating.
