Well, a few trips to the LFS landed a few additions to the tank. Most noteworthy of the bunch is a Ritteri Anemone which the store refused to sell me without buying the accompanying Skunk Clownfish (as per the previous owners request).
I believe that this set came from Bogey's tank so it's good to know that I can go straight to her for info, especially since she's local. I know Ritteri(s) like to move until they find themselves a happy-spot (as do all anemones) but this guy has remained right where I initially put him. I know this species likes lots of flow so I put him in a place where I thought he would be happy. There is about 2000gph random flow past him at most times.
Bogey stated that while in her tank, the skunk remained with the anemone most of the time. In fact, when the guy at the store removed the anemone from the tank, the clownfish remained in the anemone even out of water!

However, once placed in my 90g, the skunk clownfish began spending a lot of time around the bottom right side of the tank. Quite unexpectedly, my True Perc pair have taken over hosting the anemone and the skunk has taken to the Koralia powerhead on the right side.
Hmm... Not the best picture, but decent enough to show.
