OK guys, I will be getting 4 bettas within the next month or so (2 from wuv, 2 from inbs). I was almost decided on 2 gallon bowls, but I've decided I want to go with something CHEAP with a light. Also, for some weird reason I like the look of no gravel, and one plant inside.. What plant do you usually get? Hard to maintain it? I was wondering what you guys usually go for, as far as cube-like glass or closest thing to it- betta tanks. I'm also starting to want to "spoil my bettas as far as tank size, but not too much. Possibly 2+ gallons?
