There is one on line vendor that sells their mis barred clowns as aquacultured. They may be aquacultured but they are flawed and the sight says they are that way "on purpose".
But a wild clown is more likely to take to an anemone, but you are also sending a diver out to the reefs to stress out the livestock so you gotta choose.
If you can find an aquaculted where there was an anemone around while it was being raised, that's your best bet!!
