Hi! You've come to a great place to get information. I just recently joined as well because my sister bought me a betta for my birthday. These folks are really great and helpful.
I'd recommend at least a 5 gallon tank for your betta and make sure you have hiding spots for him in the tank. Mine has a log he likes to go in and peek out from. He's a ham. Any thoughts as to what kind of betta or colour?
If you always do what you've always done, then you'll always get what you've always got.
