This is good information. It sounds like the sexy shrimp are a no. I should have clarified. The tank is just being set up right now. No fish yet, or for a while. It is a reef that will have soft corals (zoas, mushrooms, leathers, etc.). I plan to have the shrimp/goby pair, purple firefish, one clown, and then the wrasse. Would they all work together? The reason I want the wrasse is for pest control and I like how they cruise around the tank. I think it adds depth. Would there be a better option?
