The most active...
I have been keeping bettas for about five years, and I have always ALWAYS found that when I buy the most active betta, it will be very active at home.
I know that most people say that Betta's are couch potato's and rather boring, but I am drawn to the most active in the container no matter what they look like. In fact, my first ever betta was a peach VT female who seemed to never stop moving. I have found that this has made for a more interesting friend and an easy way to tell if something just isn't quite right. What do you all think? Do you agree that active bettas are the best bettas?
