In the wild, green wolf eels, also known as carpet eel blennies, can be found in the Eastern Indian Ocean and the Western Pacific Ocean. They inhabit shallow waters of tidal flats and lagoon sea-grass beds, ranging from the Nicobar Islands to Papua New Guinea, Northwest Australia and the Ryukyu Islands of Japan.
Green wolf eels are not really eels; they are a type of fish. They are snakelike in appearance with pronounced underbites. They grow to about 18 inches in length. Though commonly green, specimens are sometimes brown, yellow or red. The green wolf eel is a voracious predatory carnivore that feeds on any fish that fits into its mouth. It also eats shrimp, crabs and other crustaceans.
Green wolf eels are easy to care for in aquariums, but they should not be kept with crabs, lobsters, shrimp or any fish smaller than they are. They need large tanks of 20 to 90 gallons, depending on the size of the fish. The tank should have sandy substrate, plenty of holes and crevices in which the fish can hide and a secure cover to prevent the fish from escaping. Green wolf eels need to be fed meaty foods, such as frozen or live shrimp, krill, silversides, crabs and chopped clams. It is important to have a good tank filtration system as these fish produce a lot of waste.
