I would really suggest against an anemone in such a new tank. Is that the only light fixture you will be running? You need at least a 4 bulb t5 setup to keep nems. That unit you linked is just a moonlight setup. Supposed to be on just at night when the lights go out so you can see inside.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
