Should I separate?

[hobbzz]

One was added last night and the other about three hours ago. They started doing the usual turning on the side about an hour after the second was introduced, but now this for the last hour. No fin damage so far. Is this too aggressive or just normal behavior when figuring out dominance? Should I separate or put them both into the sump then back into display after a few days? They are pinks btw.

It says the video is private. If you don't want people browsing YouTube to be able to find it I think the privacy option is called "unlisted" or something like that. That way only people that you give a link to can see it.

I had changed it to public already but must not have saved. It's saved now so it should work.
