Clownfish stop hosting anemone

I have tank-bred spotinchus clownfish and sebae anemone. I had the spotinchus clownfish for 5 months and the sebae for 6 days. When I got home from work, I saw my female clownfish goes into sebae anemone and not my male clownfish. I was happy but later at night, I saw my female clownfish stop hosting my sebae anemone and slept with my male clownfish on the sand bed. Then today this morning, I didn't see any of my clownfish host the anemone. Will my clownfish ever host the anemone again? Should I try to force the clownfish to host the anemone? What should I do to make the clownfish host the anemone?
