1 more tang...too many fish?

[Son Of Skyline]

I have a 120gal with a 27gal sump, and I've got quite a few fish. 4 small chromis, a small yellow tang, an average sized kole tang, a small bicolor blenny, and a nice sized lawnmower. I had a naso tang before to control macro, but it died an unexplained death and now my macro is growing again. Would it be too much to add another naso to the mix? I'm running a pretty good skimmer (Canreef skimmer) and everybody else is doing fine. I know about the "tang police" crap. Opinions?


*Flame suit on....just in case *

Thanks in advance...
