The Zebra is one of the smaller Moray's, usually no more than 2-3 feet in captivity. In the wild they get more along the size of 4-5 feet long. They are fairly popular in aquariums as they make good tank dwellers and usually eat within a week or so of being placed in captivity. You should be able to find one in most any good local aquarium store for HD shots. Most good stores won't sell one less than 12" in length, but they grow and thrive well in home aquariums.
