[Skimmerking]

I'm asking this so i don't high jack Doch's post.
I 'm doing my studying on what type of a small anemone's to put in my tank 62 gal 36x20x20. I'm going to be getting a pair of perc's and was considering a anemone of some type
or a hammer coral or a frog spawn.
what would you reffer's consider.

Or is this a bad idea, This wont be for a while where my tank os quite new and fresh..
