I currently have 3 female betta's in a 55 gallon tank, filtered and heated. There are also 7 swordtails in there with them. They all get along wonderfully. I was thinking of selling all my swords and picking up some more female bettas. My question is:
How many Bettas can I have in the 55 gallon and is it ok to mix the different kinds together?
I've only delt with the veil tail bettas (which are the ones currently in my tank). I do plan on getting at least one more female betta sometime in the next few days to make it an even four and a few more eventually.
