Care

Inimicus filamentosus requires a specialized care regimen due to its venomous nature and unique feeding habits. It is best suited for experienced aquarists who can provide a sandy substrate and ample hiding places to mimic its natural habitat. This species is a nocturnal predator, feeding on live or frozen foods such as shrimp and small fish. Caution should be exercised when handling this fish or performing tank maintenance due to its venomous spines.

Reproduction

Little is known about the reproductive habits of the Spotted Ghoul in the wild or in captivity. However, like many marine fish, they are likely to have a pelagic larval stage, where the larvae drift in the open ocean before settling to the bottom as they mature.

Habitat

The Spotted Ghoul is found in the Indo-Pacific region, from the Red Sea to Japan and Australia. It inhabits sandy or rubble substrates in coastal reefs and lagoons, often burying itself with only its eyes and dorsal spines exposed. This behavior allows it to ambush prey and avoid predators.
