diffusing wrasse aggression

[zensaiyan]

so i recently added 4 new wrasse to my 120g tank. current inhabitants are:

2 pink skunk clowns
yellow coris
mystery wrasse
solar fairy wrasse
potters angel
mag. foxface
pink margin wrasse (was female, not sure now)
candy hogfish
starry blenny
pink spot goby

i added these fish in the tank after a large water change and some slight rock moving:

large male pink margin wrasse
male lubbocks
female lubbocks
blue flasher wrasse

i expected some aggression, but i added them 2 days ago and moments ago was the first time i was able to account for all of them. soon after they came out for feeding, there was some slight aggression and they all went back to hiding.

so now my options are what? rearrange rocks? removing fish isn't really an option. thanks for any suggestions.

Which fish was picking on which?

well so far as i see:

mystery wrasse
solar fairy wrasse
pink margin wrasse (was female, not sure now)

are picking on the new ones. i did see them all, so i hope when i get home today that they come out a bit more.

How long have the existing wrasses been established? If the mystery in particular has been established for quite awhile, I think it is likely to continue to give the new additions trouble. I also think that if your existing pink margin wrasse is now male, then the new male pink margin will probably never work. By adding four at once, you did give yourself the best chance to make the aggression diffuse, and the fact that they all came out for feeding is a good sign. If removing fish is not an option (you might try a fish trap), then you could still try the old "mirror(s) on the sides of the glass" trick.

I hope you have a good top on that tank mine where fighting with my clowns and my christmas wrasse flew out and stuck in the ceiling(soft tiles) that's the third fish I have lost due to forgetting to put covers on. My wrasses all chase each other but they don't fight they play but when the clowns have eggs they chase and bite everyone.
