Welcome to R2R! I would second what @Steph72 said a lid for the wrasse (and firefish) as well as his recommendation on the mandarin. I would also agree with @bnord about the anemone. I would not call them difficult but they do need a fairly stable tank. They also tend to wander around a lot, and sometimes get themselves into trouble with filters/powerheads, if not happy. Personally I would hold off on the anemone and the mandarin until the tank has been running with stable parameters for a good six months or so. By then you should have testing/maintenance pretty much dialed in and been through most of the initial instabilities.
