Do they have personalities like bettas? Somewhat, they can get mean, though. Oh, and you can hand feed them. But I have been bitten once.
Do they recognize owners, and bond with them somewhat? Eels are practically blind, but they have high sense of smell. I'm sure they can see shadows. And my Goliath knows when it is feeding time.
P.S. I will try to get pictures of mine.
