Common name: Yellow-mouthed moray eel
General information
The Giant Moray (Gymnothorax nudivomer) is a large and impressive species of moray eel found in the Indo-Pacific region. It is known for its elongated body, which can reach lengths of over 2 meters, and its distinctive coloration, typically a dark brown or green with small yellow spots. This species is not commonly kept in home aquariums due to its size and aggressive nature, but it is of interest to advanced hobbyists with very large systems.

Care
Giant Morays require a spacious aquarium with a tightly sealed lid to prevent escape. They need plenty of hiding places and a sandy substrate to mimic their natural environment. Due to their predatory nature, they should only be housed with large, robust fish that can hold their own. A varied diet of meaty foods such as fish, squid, and crustaceans is essential for their health.
Reproduction
Breeding Giant Morays in captivity is extremely rare. In the wild, they are oviparous, with females releasing eggs that are fertilized externally by the male. The larvae are planktonic and will drift in the open ocean before settling to the bottom as they mature.
Habitat
Giant Morays are typically found in coral reefs and rocky areas, often hiding in crevices during the day. They are widespread throughout the Indo-Pacific, from East Africa to the Hawaiian Islands, and from south Japan to Australia. They can be found at depths ranging from shallow waters to over 30 meters deep.
