Black Widow Brotula Cusk Eel

Brotula are commonly referred to as Cusk Eels having a similar body shape as Eels. Some species of Cusk Eel can grow quite large, research each species to ensure your aquarium is adequate. Cusk Eels should be added to large aquariums that are well established with plenty of room to swim. Juveniles inhabit shallow coral reefs while the adults are benthopelagic, mostly inhabiting the sandy, muddy ocean floor. Cusk Eels have also been found in freshwater and brackish waters. They are carnivorous primarily feeding on bony fish, crustaceans including crabs and shrimp. A diet of meaty based foods should be provided.
