Well, females can be just as vicious as males, a lot of people don't know that. Sororities take a good bit of time to create and there's still usually a little scuffling and bickering even after things are sorted out. There's always dominance issues with them. And they can take chunks out of fish just as easy as males, some have even killed males meant to breed with them. I had one that ripped apart one of my fish, it was a cory. It just depends on the betta. I have a male that gets along in my community tank, even with a male dwarf gourami...but that's not something extremely common. Contrary to popular belief: Bettas may not get along with any other fish at all, regardless of them normally co-existing in someone elses tank peacefully. I have one that didn't even get along with snails, let alone other fish or frogs. ^^;
Turning on the Aquarium lamp in the morning is MY cup of coffee.
