There are several "compatibility charts" on the interwebs these days but in my (limited) experience, the one here at RDO does a better job than most of the others you're likely to find...
Unfortunately, just because you have a clown and an anemone doesn't mean that they will show off their symbiotic relationship. It all depends on the individual clown. It took about 5 or 6 months after I bought my anemone for my clowns to finally start using it. Still, even with the anemone in there, some clowns prefer to use coral, powerheads, even live rock as hosts.
