Thank you! Things are starting to make a lot more sense. I do want to use live plants as I figure that is more nature for the fish, and would make him more content.
The tank I picked out does have a filter on it. And I plan on getting a heater as well. I am now pretty clear on water changing and cycling.
Also thank you for the info on not using distilled water!
Are you familiar with plants suitable for a Betta? I do not want to overload the tank, but I would like an easily sustainable plant as plants are not my forte really.
