These are dual t5ho lights? You won't be able to keep a nem under those light conditions and you will also want to wait until the tank is around 6 months old before trying even if you acquire the proper lighting for it. Assuming this is a standard 16" tall tank you could easily keep softies and zoanthids. Some of my favs when I started were pulsing xenia, kenya tree, and a finger leather. The xenia and kenya tree are nice because they are the proverbial miner's canary when it comes to issues with water parameters. They will show changes when the parameters are out of whack before most other corals will, although they easily bounce back. The shrimp will eat whatever you feed the fish really. My cleaner shrimp went absolutely nuts for frozen mysis though although it was happy with flake food as well. Yes, that is true about the clowns. It's easier to buy two that live together or buy one that is quite a bit larger than the other. I bought mine from separate tanks but one was about 2/3 the size of the other and they actually didn't fight at all.
