The fimbriated moray (Gymnothorax fimbriatus) is a species of moray eel of the family Muraenidae. This species is also known by the names darkspotted moray, dark-spotted moray eel, fimbriated moray eel, spot-faced moray eel, spot-face moray, and yellow-head moray eel.
This is a medium-sized moray that has a serpentine body. The yellow-head moray is widespread in the outer slopes of coral reef areas, lagoons, top reef areas, and harbors in the native range of Indo-Pacific water areas. They are found at a depth of up to 164 ft (50 m).
Fimbriated morays open and close their mouths to let water enter their gills for respiration. This is how they live in the marine environment.
The identification of the fimbriated moray can be done by the pale coloration on the adults. They have small black spots on the face and the spots change size with age.
The spots become large with age and the large spots start joining with age into vertical bars. The mouth has teeth that help in tearing the flesh off prey rather than grinding.
Moray eels stay in the wild environment hidden and only come out of the lair at night to hunt for prey along the reef.
The distribution range in the wild is found in Madagascar, Polynesia, south Japan, and New Caledonia and they feed on fishes, shrimps, and crustaceans. However, in captivity, they can be given food like scallops, shrimp, fresh squid, fish, and flesh of crustaceans.
They should not be kept with small fishes unless the fish is more than 20 % of the body size of thwaw moray eels.
