The Condi isn't a normal host for clownfish at all, but it can happen.
As to wild perc's in the home aquarium, anything can happen when you put an anemone in the tank, you just have to trust to luck. However tank raised clowns are much better to work with and I believe you would stand a better chance of them taking to an anemone.
Clowns have been known to use several other corals to frolic in so it is possible to see them in a leather, xenia, hairy mushroom, star polyps even your aquarium magnet.
None specific but I hope that helps.
