What is a good saltwater fish to keep in an aquarium with a clownfish, royalgramma blet, and 6 line wre?

I have a new saltwater tank and we want some really cool fish to put in the tank. We already have 2 clownfish, a royal gramma blet, and a six line wre. Is there any other really pretty and colorful fish that would do well with the aforementioned fish?
