Trouble with new addition

Hey guys...well I have a 90 gallon reef tank, lots of LR and hiding spots. My tank is on the taller cubish side so lets keep that in mind too, with mid level and up available for clear swimming. Okay, so my tankmates have always lived in harmony together until recently. I currently have a
Pink skunk clownfish
Scissortail dartfish
Blue assessor
Tanaka pygmy wrasse
Tomini tang
and added a Black and white chromis or bi color chromis you could say.
Question comes now. So I'v never seen any aggression towards anyone in the tank up until when I added the chromis. I added him, and for the first 2 or 3 days the tang sorta chased him around a bit...looked like he nipped the back of his fin a tad. Lets fast forward to a couple of weeks, his fins grew back fin...however I went away for 2 days on vacation and noticed my blue assessors top back fin was kinda like had a V shape tear in it? Not frayed...like a cut almost. So I have been observing the fishes behaviors for a couple of days now...the blue assessor seems to be able to eat fine and not be harassed by anyone...the only think I noticed is that the Chromis will do a little mini chase that last all of a second and the two fish go there separate ways. I will also say it looks like maybe the assessor is trying to find a new "territory" so to say. He seems to be wondering over to the pink skunk clownfish area and I'v noticed some very slight aggression with the skunk towards the assessor I had not noticed before he chromis was added...and the tang of course is no longer an issue from what I can tell...do you guys think this will get worse or is mother nature just trying to balance itself out? I also had inquired from BlueZoo Aquatics on the chromises aggression before purchase and they assured me that with the tank mates I have now that the fish is a peaceful fish and should not cause problems...however the chromis did not come in the small size they said it would and looks more on the larger side of adulthood.
