Female Community Tank
Back when I kept female betta communities instead of gouramis, I used to house between three and seven in a 10 gallon aquarium. I got very lucky and had pleasant ladies who largely got along wonderfully. :3 It got me thinking though...is there any sort of an upper limit to the tank and school size for female bettas? I've never kept any in medium (25-40ish gallons) or large (55+) tanks. I'm setting up my empty 75 gallon as a lush planted tank in the fall when I move and I'm wondering if lady bettas might be another possibility in addition to more gouramis, goldfish, or some sort of Amazon biotope.
