As far as your anemone is concerned you want to make sure that your parameters have been stable of at least 6 months before introducing one. My choice would be an Green or Rose Bubble Tentacle Anemone.
As far as fish are concerned, it's pretty much an individual choice. Personally, I look for gobies, blennies, grammas, baslets, and maybe a dwarf Angel as a feature fish. If it were my tank I'd consider a lawnmower blenny, a royal gramma, a sixline wrasse, coral beauty, and maybe a yellow watchman goby and pistol shrimp. Remember, those are only my choices and would result in a full tank. I'd introduce them slowly, one at a time, probably with several months between additions.
