Care

Kidako Morays require a large and well-structured aquarium with plenty of hiding places to mimic their natural rocky crevices. They are escape artists, so a tightly fitting lid is essential. These eels are carnivorous and should be fed a varied diet of meaty foods such as fish, squid, and shrimp. It's important to feed them with tongs to avoid accidental bites, as they have poor eyesight and rely heavily on their sense of smell.

Reproduction

In the wild, Kidako Morays are oviparous, with females laying eggs that are fertilized externally by the male. In the aquarium, breeding is rare, but if conditions are right, they may spawn. The larvae are pelagic and would require specialized care to raise successfully.

Habitat

Kidako Morays are found in the Western Pacific, from southern Japan to the Philippines and south to the Great Barrier Reef. They prefer reef environments and are typically found in crevices and holes within the reef structure, at depths ranging from shallow waters to about 50 meters.

Hobbyists should note that while Kidako Morays are fascinating and beautiful, they are also powerful and potentially aggressive. They are best suited for a species-specific tank or with other large, robust fish that can hold their own.
