The best thing you could do is, get you about 20 pounds of live rock first, then add a couple of false percula or some other type of clown fish, then wait about a wek or so and then get some kind of goby or some little invert (CORAL BANDED SHRIMPS DO WELL) and just try to keep your load small, fire gobys arn't bad but they are not that hardy, damsels are very mean, but they don't seem to bother clowns that much. If you take it slow and monitor your levels you should not have to put a skimmer on it. But it is recomended that you do. But then again I would not recomend a 20 gallon either, a 55gallon setup wouldn't cost you that much more, but would be way more suitable. P.S. I sell salt water fish!
