None of the species of clown fish will ever host a condi in the wild. You may get lucky in a tank and have a clown host in it but it isn't a natural association. I have had clowns host in several types of corals including hammers and bubble corals. Of course that was not natural either but I didn't have an anemone available for it at the time. I would seriously consider Wendy's suggestion on the carpet anemone if I were you. Especially if you are trying to get a mated pair and have them breed.
There is a great little book on anemone fish and their host anemones by Daphne G. Fautin and Gerald R. Allen.
