If you are looking to start from square one, I'd suggest you'd read the FAQ in the Betta Care Section. I also compiled this list of stuff I have for my current betta tank that is a 5 gallon capacity.

I also have my most recent tanks status and some more pictures of the tank set up later in the thread!
