The one I have my eyes on is eating out of thier hand 2-3 frozen (thawed) large shimp a day. He will come to the front of the tank and wait for you when it is hungry and take the food gently from your fingers. They keep it in a open top tank without any problems. It is 28"-30" long and they say this type of Zebra eel has a max. of 3.3 feet.
I only have 2or3 shimp that I very rearly get to see. The 2 things I am worred about are the sally light foot crab and my reef lobster. other than that I think with what I have received from your words I will go for it.
