He's cute! I'm glad you've taken such an interest in bettas. Remember that it's not always good to rush into a hobby, and fishkeeping is no different. Make sure you don't acquire to many fish to fast. I wouldn't want ya to look around one day and realize you're overwhelmed.
Edit: I didn't mean you won't keep interested in bettas. It's just that I've known a few people who love that they can pick up a new fish anytime they're at the store. Everything is great for a month or so, but then they lose interest and have 5-6 unwanted bettas that aren't getting proper care.
Just remember that there will always
be another fish. You'll be able to realize when you're spread too thin.
