Care

Caring for a Liver-colored Moray requires a spacious aquarium with a secure lid to prevent escape, as moray eels are known for their ability to slither out of tanks. They need plenty of hiding places and crevices within live rock formations to feel secure. This species is carnivorous, feeding on a diet of fish, squid, and crustaceans. It is important to feed them a varied diet to ensure proper nutrition.

Reproduction

In the wild, moray eels are solitary creatures and come together only to breed. Little is known about the breeding habits of Gymnothorax hepaticus in the wild or captivity, as breeding moray eels in home aquariums is quite rare.

Habitat

Gymnothorax hepaticus is found in the Indo-Pacific region, from the eastern coast of Africa, across the Indian Ocean, to the western Pacific. They are typically found in reef-associated environments, often hiding within crevices and overhangs during the day. They are nocturnal hunters, coming out at night to feed.
