Chestnut Moray

The Chestnut Moray is a robust and attractively colored moray eel native to the Eastern Pacific, ranging from the Gulf of California south to the Galapagos Islands. Its body is uniformly dark brown to chestnut in coloration, sometimes with a subtle greenish or olive tinge, giving it a handsome and somewhat understated appearance compared to more flamboyantly patterned moray species. Reaching a maximum size of approximately 24 inches, it is one of the smaller Gymnothorax species, making it somewhat more manageable for dedicated aquarists.

In the wild, the Chestnut Moray inhabits rocky reefs, tide pools, and boulder-strewn coastlines, where it shelters in crevices during the day and emerges at night to hunt fish, octopuses, and crustaceans. It is a voracious predator with the typical sharp, recurved teeth of the Gymnothorax genus, capable of seizing and holding struggling prey with remarkable efficiency. This species is known for its bold and sometimes aggressive temperament, readily defending its territory against perceived intruders.

In the aquarium, the Chestnut Moray requires a well-established tank with abundant rockwork providing multiple caves and hiding spots. It is decidedly not reef-safe and will consume any fish or crustacean small enough to capture. A heavy, secure lid is mandatory, as this species is a powerful and persistent escape artist. Strong filtration is essential due to the messy feeding habits characteristic of predatory moray eels.
