Gymnothorax

Gymnothorax melatremus

Schultz, 1953

Golden Dwarf Moray, Yellow Moray, Pencil Moray

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: East Africa to Hawaiian Islands, Marquesas and Mangareva Islands, and south to Austral Islands.

Size: 7 inches (18 cm)

Natural Environment: Inhabits surge zones in seaward reefs at depths between 3 to about 200 feet (1 – 60 m) and and stays under rocks and/or in caves during daytime and hunts prey during evening hours when it feeds mainly on smaller fishes and crustaceans.

General Husbandry: Somewhat unusual and rare in the trade, however a gem if interested in having a very small moray in the aquarium. Has a light brown to bright yellow to white body with deep blue eyes.

Best maintained in an aquarium having hiding places/caves large enough to conceal its entire body, and peaceful tankmates.

As to diet, fresh fish and/or crustacean flesh impaled on a long feeding stick and waved near its head, which usually sticks out of a hiding area, will entice it to grab the food and should be offered twice weekly.

Taxonomy:

    Order: Anguilliformes

    Suborder: Muraenoidei

    Family: Muraenidae

    Subfamily: Muraeninae

    Genus: Gymnothorax

FYI: Avoid hand feeding!

Ideal community fish.

Highly secretive.

May eat ornamental crustaceans.

If difficult to get feeding, try providing it live ghost/grass shrimp and/or small crabs, e.g., fiddler crabs to induce feeding.

Aquarium must be covered, as they can get out of the aquarium through very small openings.
