Heh, I've just gotten into the wonderful world of Bettas, and I'm already addicted! I adore mine, and I have to fight myself from bringing home another every time I go to the pet store.
I almost bought one today, but out of the two I liked, I think one was dead and the other had tail issues. I'm already working on trying to make sure my guy doesn't have a chewed tail/tail rot, and I didn't think taking on a second fish with potential health problems was a good idea when I have zero experience with them, so I put him back. I feel a little bad about it, though.
