I have always had Auratus. I love them. They have really spunky personalities, and in my experience, they only harass themselves, and in that context, only the males harass the females. But in most cases, they are chasing each other playing around, it never gets vicious. The only thing that people who have never kept auratus before might not like about them, is that the males are not very attractive, and they get worse as they age. That being said, they have great personalities, and are fun to breed as well.
