tanks needed for 2 m, 2 f bettas?
I'd like to get two breeding pairs of bettas, that is, two males and two females. I'm wondering what sizes and how many tanks I will need, just for permenant housing for these four fish. What volume should I allow for each fish?
Obviously the males can't be housed together or with the females. I was thinking though, in terms of cycling and maintaining the tank, that it might be better to have bigger tanks with more fish rather than individual tanks. So, maybe two tanks of the same size, one for the two females, and one for the males, but with a divider of some sort. (I've heard of dividers, but I don't know how I'd actually use or install one.) I can't think of any way to get all 4 in the same tank, but I'm open to suggestions!
