My boyfriend and I had a betta in an 8gal biOrb. (this was a couple years ago, about the only thing we did right)
We wanted to add more fish, but the Petco employee told us only goldfish, since everything else was tropical and needed a heater.
Then I remember reading/being told that bettas lived in puddles and would freak out in big tanks.
Poor Mikey, hardly any water changes, no heater in a 60*F house, no plants. We always wondered why he just laid in the tank. Sigh. He lived 2 years. RIP
