Juju was about 2 1/2 inches and Kissyboots is about 2 inches. Finfin's still only about 1 1/2 inches. I hear they live about two years, but you don't know how old they are when you get them. My friend's betta has been alive for over three years. I guess it depends. Oh, and they don't eat flake food, you have to get "betta bites" or something.
