Genus
Common name: Snake Eels
Scientific name: Callechelys
Callechelys is a genus of eels in the family Ophichthidae, commonly known as snake eels. These eels are characterized by their elongated bodies and reduced fins. They are found in sandy or muddy substrates in tropical and subtropical seas, where they burrow to hunt for prey such as crustaceans and small fish. In the aquarium, they require a deep sand bed to mimic their natural burrowing behavior and may be shy or reclusive. Their unique appearance and behavior can add an interesting dynamic to a well-established reef or fish-only tank.
