Green Eel (LiveAquaria)
The Green Eel, also known as the Green Moray Eel, is yellow-green in color and can grow to over 7 feet in length in the wild.
In its natural range, the Green Eel poses a problem for divers who carelessly stick their hand into a crevice. In the aquarium, it can pose a major risk as well, especially as it grows.
Typically, the Green Eel is available as a juvenile, only a foot or so long. It grows quickly though, and will start consuming tank mates. It has also been known to bite its owner’s hands at feeding time.
The diet of the Green Eel should include live fish and all meaty foods.
There are accounts of individual specimens growing over five to six feet long in an aquarium. The Green Eel is also an escape artist and will try to go through any small opening in the tank.

Anna Peters –
I bought this eel for a large marine tank, but after a few weeks it started biting my hand during feeding. I had to move it to a separate enclosure. Not recommended for beginners or small tanks.
Stephanie Cornish –
The eel arrived healthy, but it quickly grew and began attacking my other fish. I had to remove it from the tank. It’s not suitable for community tanks.
Maria Smith –
I was warned about the risks, but I still got it. It escaped through a small gap in the tank. I now have a reinforced enclosure and a larger tank. Only for experienced aquarists.
Austin Vaughan –
The eel is very active and eats live fish. I feed it every day with frozen meat. It’s not a pet for casual owners. Requires constant supervision.
William Coleman –
I regret buying this. It bit me during feeding and damaged the tank wall. I had to quarantine it and now I’m afraid to keep any moray eels.
