I have 2 occ clowns (1 orange, 1 black), a midas blenny and a coral beauty in my 29. None of them are full grown and I will be starting my 90 gallon in July but they are all happy together and the water quality is quite good, maybe not sps good but my lps and softies are growing great. I think with proper maintenance you could be fine. Make sure you have plenty of caves in the rocks and a lot of live rock. The coral beauty and the wrasse may not get along if they have to compete for sleeping area in the rocks.
