Ok, this is the second post you have bumped. I cannot say for sure as I am a new member, but most aquarium forums prohibit this. Even if they don't it's rude IMO to force your thread up the charts because people are going to assume there is new information posted. Now that I have said that.
You have plenty of lighting options for a tank that size that would allow you to keep pretty much any coral that may interest you. It really depends on your budget, but if money is no object an LED fixture like the AI SOL comes to mind.

They can be a bit pricey but that is the "new school" way. I am more of an old school halide fan. With your tank, a 150w pendant would work great. The upfront cost would be much less than the LED's but the replacement bulbs are a little high and don't last too long. Depending on the brand and how long you run it, 5-9 months is about all your going to get out of the bulb.

Something similar to that would work great IMO. Plus I love the look of halides.
