I don't think so, Jakie - this one has been nurtured by a very
caring owner for many years. I *think* I saw posted that Mr.Eel was 7.5 years old when this video was filmed! I was wondering the tank size, too. I'll have to scroll through the comments. Perhaps he has it listed.
Either way - GORGEOUS animal, and I just adore the interaction. . . all around lovely!
