Damsels are notorious for being **** heads.
Many people recommend to always add a damsel last and 4 sounds like asking for problems.
However, I can't comment from personal experience on Damsels, as my single yellow tale is the most whipped fish in my tank. My Anthias does not let my damsel come out and swim, never mind give him the opportunity to act like a typical damsel.
My mirror here is located between the 4 pieces of tape seen.
I had to take the mirrors off as my Wrasse was spending too much time going nuts of them too, he was trying to offer food to the mirror fish... But when the Anthias acts up again, the mirror goes back up for a few hours.
