Thank you for the suggestions/support, everyone!!!!

After adding the female guppies, things have calmed down for the girls. Hopefully, this will have done the trick.

The guppy ladies are all fine and shred free. The betta ladies' shreds are fuzing back togther, and there has been no new injury since the guppies were added.

Hopefully it will stay this way. I didn't intend to put the guppies in here, but I suppose it will be fine for now. Besides, the bettas can grow big and strong on a diet of fry. :b

It's really quite entertaining to watch them all. The bettas are a much smarter bunch of girls than the guppies. The lady guppies are actually kinda dumb!!! 8o
