Gymnothorax

Gymnothorax vicinus

(Castelnau, 1855)

Purplemouth Moray

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Atlantic Ocean: Southern Florida, Bermuda, Bahamas, Caribbean, and northern South America.

Size: 50 inches (125 cm)

Natural Environment: Inhabits coral and rocky reefs at depths between 3 to about 400 feet (1 – 120 m) and stays under rocks and/or in caves during daytime and hunts prey during evening hours when it feeds mainly on small fishes and crustaceans.

General Husbandry: Rarely seen in the trade, having a pale yellow to tan body with darker markings.

Best maintained in a dimly lit aquarium having live rock, hiding places/caves, and tankmates large enough not to be eaten.

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.

FYI: Avoid hand feeding!
