What's the first thing you put in your reef?

I started up with one blue damsel and a clean up crew of half a dozen snails and hermits.
I went a little crazy on corals frags on start up and now that my tank is thriving the corals are completely covering all of the LR.
I picked up a Pom Pom Xenia and a Pulsing Xenia both. They are beautiful but they spread like the plague.

My regrets....
The blue damsel is a huge bully and he seems to get worse as he gets older.
All of the corals are doing great but the tank is starting to look crowded. Next time I will pick and choose the corals more carefully and grow out large colonies of each.
I will never again have any Xenia in my SW tanks...or any other similar coral.

I don't remember the first thing I put in but my biggest regret was a piece of live rock with some colt coral on it. Wouldn't wish that crap on my worst enemy!
