General information

The Snowflake Eel, also known as the Clouded Moray or Starred Moray, is a distinctive and popular marine fish among aquarists. Echidna nebulosa is known for its unique and attractive pattern of black blotches and spots on a white to yellowish background, resembling a snowflake design, which is the origin of its common name.

This species is relatively hardy and can be a good choice for a fish-only or a larger reef aquarium with caution. It's important to note that while they are generally peaceful towards fish of similar size, they may prey on smaller fish and invertebrates due to their carnivorous nature.

Care

Snowflake Eels require a well-secured aquarium with a tight-fitting lid to prevent escape, as they are known to be skilled at finding their way out of tanks. They need ample hiding places and a sandy substrate to burrow. These eels are nocturnal and prefer to hunt at night. They can be fed a variety of meaty foods such as squid, shrimp, and fish.

Reproduction

In the wild, Snowflake Eels are oviparous, with females releasing eggs into the water column to be fertilized externally by males. Breeding in captivity is rare and not well documented.

Habitat

Echidna nebulosa is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands and the Marquesan and Ducie islands, north to southern Japan, and south to Lord Howe Island. They inhabit lagoons and coral reefs, often hiding in crevices during the day and emerging at night to feed.
