Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean: Indonesia, Papua New Guinea, Solomon Islands, Tokelau and Kapingamarangi in Micronesia.
Size: 20 inches (50 cm)
Natural Environment: Inhabits shallow lagoon reefs at depths between 3 to about 25 feet (1 – 8 m) 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: Very rarely seen in the trade and quite drab. Has a dark bluish to black, sometimes a mottled brown body.
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.
Taxonomy:
Order: Anguilliformes
Suborder: Muraenoidei
Family: Muraenidae
Subfamily: Muraeninae
Genus: Uropterygius
FYI: Avoid hand feeding!
This is a very aggressive species.
Aquarium must be covered, as they can get out of the aquarium through very small openings.
Rockwork in the aquarium should be quite stable, as they can undermine rock structures and cause their collapse.
May be difficult to get feeding, if so, try feeding small live fishes, ghost/grass shrimp and/or small crabs, e.g., fiddler crabs.
