Please help me in deciding on Fish for 100 gallon Saltwater tank?

I inherited a tank and have been working to learn and get it up to speed. I now have it where I understand better but still not sure as mixing fish together. It's a Coral reef tank and has 2 clown fish and 4 Tangs (Yellow, Hippo, Yellow Tang and Purple) I'd like to add two more fish that are beautiful in color and good active swimmers around the tank but don't want to get the wrong ones and have them fighting or destroying the corral...I've been reading a lot and have saw some different fish I liked but it would be great to get feedback from people who know or have them in their tank already. Having a tank is a lot of work but I love it, so much fun to see the fish and it's very calming glad that it got ped on to me. Any suggestions or feedback would be great...Thanks all!!!
