I've bought so many small tanks the past 2 months and fell completely in love with Bettas! I have 4 right now. Tom my crown tail male, Xena my red veil tail female, Kora my blue/black stained glass looking female crown tail, and Baby Wookie my (hopefully) female betta that could be a crown tail.
I originally got a 16 gallon for rasboras, but these bettas are just getting more and more interesting. It's then that I decided this tank deserves a group of females. I've already started collecting suspects. 2 females of same size and both seem pretty mellow. They're in a divided tank right now and can barely see each other. They never flare at each other when they look at each other, more of just curiosity. I need a lot more, maybe up 6, but 4 minimum. I'm keeping them divided in other tanks until I'm ready to start introducing them to each other in the 16 gallon starting with the least aggressive.
I have read some, but there is not a lot of information around on this. Any tips that anyone can give me on starting a sorority?
For tank mates there are 2 nerite snails, a CPO crayfish (less aggressive species), and cherry shrimp on order. There are lots of real plants and I'm also trying to build more ground cover for the shrimp. I've had success with shrimp in my male betta's tank.
