Care

Crocodile Snake Eels are not commonly kept in home aquariums due to their specialized care requirements and large size. They can reach lengths of up to 1 meter (3 feet), necessitating a spacious tank with a deep sand bed for burrowing. These eels are escape artists, so a tightly fitting lid is essential to prevent them from leaving the aquarium. They are carnivorous, feeding primarily on small fish and crustaceans, and may require live food to initiate feeding in captivity.

Reproduction

Little is known about the reproductive habits of Brachysomophis crocodilinus in the wild or in captivity. They are presumed to be egg-layers, but breeding them in a home aquarium setting is extremely challenging and rarely attempted.

Habitat

Crocodile Snake Eels are found in the Indo-Pacific region, from the east coast of Africa to the western Pacific Ocean. They inhabit sandy and muddy bottoms in coastal waters, often burying themselves with only their heads exposed to ambush prey. Their habitat ranges from shallow lagoons to deeper waters, typically up to 30 meters in depth.
