![]() They will not harm corals in a reef environment, but are more suitable to FOWLR systems due to the fact that half of the cleaning crew may be added to the dinner menu. Tank mates should be considered carefully and can generally be other large predatory species (i.e., Groupers, large Angels, Puffers, Boxfish, Scorpion fish, Lionfish, Butterflyfish, etc.). These dens are any place that a wolf eel finds desirable, such as a cave, hole or rocky outcropping in a reef that is large enough to hide in and provides safety from predators. They get their name from their Wolf-like head, which is large and flat. They make their homes in denscaves or crevices on rocky reefs or pilings.

This species should not be kept with shrimp, small lobsters, crabs, or any fish that can fit in its large mouth as they will quickly become snacks (large hermit crabs and snails should be fine). Wolf eels are a type of fish that is found in the Pacific Ocean. The wolf eel (Anarrhichthys ocellatus) is a species of marine ray-finned fish belonging to the family Anarhichadidae, the wolf fishes. The wolf fish is common along most of the Norwegian coast. In addition to quality biological and mechanical filtration, an efficient protein skimmer is also recommended as Wolf Eels can be quite gluttonous when feeding and will have a large biological load on the system. Range & Habitat: It is found from the British Isles in the east to the coast of Maine in the west. They are not generally known to be jumpers, but should be kept in an aquarium with a hood or tight-fitting lid to help prevent their escape. Those are pectoral fins and that is why the wolf eel is not a true eel like the moray eel Wolf eels can grow up to 8 feet long. Milton Love notes "They are good to eat and some northwest Native American tribes reserved this species for tribal healers.Wolf Eels require an aquarium of at least 90 gallons along with plenty of live rock for hiding and hunting (they love caves and crevices) they should also be provided with a fine, sandy substrate as they often rest on the bottom of the aquarium, laying in wait for prey to crawl or swim by. Large wolf eels can be aggressive and inflict painful bites on humans. Wolf eels tend to live in caves or cracks between boulders and feed on crustaceans (crab and shrimp), as well as urchins, mussels, clams, and the occasional. They will pick a territory in a crevice, den or lair in the rocks. The wolf-eel makes its home on rocky reefs or stony bottom shelves from shallow to moderate depths. In Southern California, wolf eels are found at the deeper edges of recreational limits (often deeper than 100 feet) in relatively cold water. They are found in the northern Pacific Ocean, ranging from the Sea of Japan and the Aleutian Islands to northern California. Zig zag eels from Borneo only grow to four inches and since they are small eels, in the aquarium as in nature, they need a hiding place to feel secure. They swim by making deep S-shapes with their bodies, like a snake moving across the ground. ![]() They can grow to be 203 centimetres (80 in), 18.6 kilograms (41 lb). Wolf-eels live in shallow water as deep as 740 feet (225 m). Average adult size: Adults can grow to be more than 6 feet long. This superficially eel-like fish feeds on crustaceans, sea urchins, mussels, clams and some fishes, crushing them with its strong jaws. WOLF EEL Anarrhichthys ocellatus Habitat: Wolf eels typically are found in caves and crevices on rocky reefs. The Wolf eel is monotypic within the genus Anarrhichthys. The Wolf eel ( Anarrhichthys ocellatus) is a member of the family Anarhichadidae together with the wolffishes of the genus Anarhichas.
