It's actually my daughter's fish. I think we've had him for a three or four years now. His name is Frodo. He started out in a bowl, then he graduated to a 5 gallon aquarium, now he's in a 10 gallon aquarium. My wife says his next aquarium will be somebody's pond!

They can get pretty big. I bought a few fancy goldfish when I was a teenager and put them in a 20 gallon aquarium...wow!
