Kidako Moray

The Kidako Moray is a robust temperate to subtropical moray eel native to the Western Pacific, particularly common around the waters of Japan, South Korea, and Taiwan. Its body is uniformly dark brown to brownish-gray, sometimes with a subtle mottled or reticulated pattern that becomes more visible under close inspection. Reaching approximately 31.5 inches in length, it is a solidly built medium-sized moray with a muscular body typical of the Gymnothorax genus.

In the wild, the Kidako Moray inhabits rocky reefs, boulder fields, and temperate coral communities in relatively cool subtropical waters. It is a nocturnal predator that shelters in crevices and under ledges during the day, venturing out at night to hunt fish, crustaceans, and cephalopods. The species is well-adapted to cooler water temperatures compared to most tropical moray species, and this is an important consideration for aquarium care. In Japan, it is one of the most commonly encountered moray species by divers and fishermen.

In the aquarium, the Kidako Moray requires a well-established system with cooler water temperatures reflecting its temperate origins. It is an aggressive predator not suitable for reef or community aquariums. A secure lid is absolutely essential. This species can be hardy and long-lived in captivity when maintained at appropriate temperatures and provided with a varied diet of meaty marine foods. It is less commonly available in the aquarium trade compared to tropical morays.
