the wrasse would be the last fish you want to add to the tank. the absolute last. since your new to the hobby I suggest the blue Chromis and a lawnmower Blenny. be sure to have a clean up crew established before adding fish. and I've been running a single voyager 8 powerhead and my corals look amazing for a 6month reef tank. Will be investing in a protein skimmer soon. algae driving me nuts
