The multies, the comp, and the rainbow will not like the tropheus level of activity. I have kept leleupi with mine and currently have a juli in with them without problems. I did keep some calvus in with them for awhile, but it was a calvus who had a horrible disposition and had no problems defending himself. I have had 11 calvus/comps over the years and he was the only one I thought was capable of keeping in their tank. I would never keep my multies in with them.
Of course, I am talking about my colony, but the activity of one would still be high, and it would affect your fish. If you want something that is active and not going to have an adverse affect on your fish, try to get an LFS to bring in some cyps. I know they were brought up in another thread as being bad shippers - this way the LFS absorbs the cost of loss.
