Thanks, the rock is two pieces I had from my last 90 breakdown. I plan on a purple firefish, tank bread oscelaris and a small RBT nem. Once the nem settles, I will go with some rics and Zoa's. There is enough room in the back to run a small skimmer and make a small fuge-which I plan on doing. The lights are bright and very nice. We shall see how the corals like them but all the reviews have been good as far as par readings.
