I can't wait to keep a betta but I don't know what type to get - I don't know much about these fish
Easiest fish to keep in a small tank. Just wouldn't put any other fish with it. They don't need filtration.
Petsmart has a good selections.
Also Nov 1 an aquarium
association in Ohio is having an auction. It is at Tallmadge Community Center, 80 Community Drive, Tallmadge, Ohio
