I had a two foot zebra moray that loved to be pet. When I would feed him with a shrimp on a stick he would attack it like a rabid dog, when I would hold the shrimp in my hand he would come and take it very gently. Then if I was doing something in the tank, he would always come out and rub against my hand. If I would move him away, he would come right back. Crazy Eel.
