In my experience, the time frame for clownfish to accept an anemone as host is between 5 seconds and several years.
Natural hosts are generally accepted right away while the acceptance of other anemones may take some time and convincing.
The above is primarily for wild-caught an F1 generation anemonefish who's parents were in a natural host. Highly domesticated clownfish who's parents may or may not have seen any anemone may behave very different.
