Tomato clowns can get very mean. One or two of them would get quite aggressive with age. Consider a different clown if that is what you are interested in. Occelaris, Percula and Skunks are the mildest mannered clowns. I would avoid dwarf angels if you have corals. You just never know with them.
Other wrasse's should be okay including the yellow coris wrasse. I have one in my system and it is a model citizen. Just be aware that wrasse's are jumpers, so you should probably have a canopy of some sort. Wrasse's are typically some of the mildest mannered reef fish there are, and come in a lot of different bright colors.
You might want to consider a midas blenny as well. I love mine. It is nicely colored, always out, although it "perches" on a lot of things, so not always swimming, and very mild mannered.
A single chromis will add something different as well, but I'd avoid a "school" as they slowly kill each other off with age.
You have a fairly mild mannered group of fish, so a firefish should work as well.
