Common name: Barred snake eel

General information

The Harlequin Snake Eel, also known as the Banded Snake Eel or Yellow-headed Snake Eel, is a striking species that adds a unique element to any marine aquarium. Myrichthys colubrinus is known for its elongated, snake-like body and distinctive color pattern of alternating black and white bands, with a yellow to orange head. This eel is a member of the Ophichthidae family, which includes various species of snake and worm eels.

Care

Harlequin Snake Eels require a well-established aquarium with a deep sand bed for burrowing, as they are adept at escaping from tanks if not properly secured. They are generally peaceful but may prey on small fish or crustaceans, so tank mates should be chosen with care. These eels are carnivorous and should be fed a diet of meaty foods such as fish, squid, and shrimp.

Reproduction

In the wild, Myrichthys colubrinus is oviparous, with eggs hatching into larval eels that are part of the planktonic community before settling to the bottom as they mature. Reproductive behaviors in the home aquarium are rare, and captive breeding is not commonly reported.

Habitat

Harlequin Snake Eels are found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian and Easter Islands, north to southern Japan, and south to New Caledonia. They inhabit coral reefs and sandy areas, often burying themselves with only their heads exposed, and can be found at depths ranging from shallow waters to about 50 meters.
