I respectfully disagree with Myka on the lighting front. If you eventually want to go into SPS, or possibly clams, I would recommend you go to MHs. If you jump from lighting set up to lighting setup it will cost you more in the end rather then just biting the bullet once. However, if you think a tank with mostly soft corals is what you want then consider T5s. The initial purchase cost for T5s is also up there though, and in the long run they work out to be about just a much as MHs to maintain in terms of lighting replacements etc.
