I have two females which I got a week ago now. The orange one always seems submissive to the white bigger female and followed her around. Today for some reason the white one is constantly chasing the smaller one. Even if she's at the other end of the tank she'll zoom over and have a go at her. Poor orange one has spent most of the day hiding in the plants out of the bully's way. I also saw her have a go at my betta boy, but he wasn't having it and soon turned to her and she backed right off.

Why is she doing this?

It's a 35L cycled tank.
