20Gal - Lighting Recommendation

[mia_reefer]

All,

Thanks in advance for your replies. I have a 20gal innovative marine tank and looking into some lights. My aquarium will eventually have some live-rock, anemones, a clown and wrasse, and a cleaner shrimp.

I know lighting is very expensive and I am absolutely clueless when it comes to sufficient light. I was looking at the exxotic 12.5 inch stunner lights.

I am not sure how many lights I would need nor if this is a good light.

Thanks
