How many bulbs do you have? 65w each? Power Compacts?? If you have multiple bulbs that's 65w each of power compacts, it doesn't mean you can't keep any corals. Mostly softies of course, stuffs like Leathers & Mushrooms. Some people have success keeping some LPS corals with such lighting in a smaller tank. With a small tank like yours, you will only be able to keep a few small fish like I've mentioned earlier. Stuffs like Chromis, Clownfish, firefish, etc. I wouldn't recommand Damsels, they can be quite mean! But some people have good luck with'em and like'em very much. Start by research and read up on everything you can. Good Luck! :happyfish
