Yes I could keep the water clean but my fish explore so much and roam their whole tanks that I couldn't imagine keeping them so bored. But maybe that's just me.
Nah, it's not just you, lol. I feel the same way. I tend not to get involved in such discussions on tank size in this forum because it seems that many here believe the small containers (less than or equal to 1g) are fine for them, and I wish not to ruffle any feathers.
My own personal minimum is 2.5 gallons. And the reason for that is space availability. I realize that it is entirely possible to keep tanks smaller than that clean and healthy for our bettas, provided maintenance is never slacked on. But having seen how inquisitive these creatures are and how much every one of the ones I've had seems to absolutely love swimming through all the nooks and crannies leads me to wonder how one could decorate a tank smaller than 2.5 enough to keep them entertained, when even I can't be next to my bettas 24/7 to make faces at them and talk to them...and I'm a stay at home mom and home all day.
To each his own, I'm not knocking what everyone else does. But those are my reasons for saying 2.5 gallons is a good minimum. ;)
