I know that taking care of a fish is demanding so I'm only considering a tank between 5-10 gal. This is for my college dorm. I already have a betta so I'm wondering what else I should try to fit in a tank that I'll buy soon. Right now, I have just a betta in a 3 gal bowl which needs to be upgraded. I want to keep my betta because it's not too hard to care for. I'm looking for suggestions regarding things that I can add to my betta's future tank. Thanks.
