Fish aggression habits.

[ReefReadyYouTube]

I got two pink smith damsels from my LFS and they were in the same tank acting all fine and friendly. The LFS just got them in that week too. Then when I put them in my tank, which are the only two fish in there, one is beating up the other. Why is this? Is it because it’s a new tank and need to establish Territory? How long would this last if it is. Also it’s only the one damsels that’s being mean. Thoughts?

Most damsels are terrors and won't tolerate another.
