I have some christmas money coming my way and I was day dreaming about putting some corals in my 75 gallon tank. The inhabitants are 1 ocellaris clown, 2 firefish, a clown goby, and some small inverts (except one large cowrie). Right now I have 130 watt 50/50 pc lights. I would like to try to keep some zoos, polyps, and mushrooms. My questions to you is what lights should I buy? My odyssea equipment works well for me and I was thinking of either the 20" 223W Metal Halide Fixture or 48" 260W Dual Strip Compact Fluorescent Light Fixture. Anything I keep in the tank would probably be at the mid level and maybe at the bottom. These would be in addition to the light I already have.
