Bro, observe for a few days, as long as the big clown is not hostile to the small one, chance quite high. The small one may be stressed. Do monitor Their behavior(how they swim) and body for disease. Continue confinement till unsee the small clown and big clown swim together. It can take weeks. Some so called paired clown are also not real pair, just that they don't fight. So when buy pair, ensure no fight and torn fins, however, my maroon clown paired after the small one was whacked and later they got together. Lol.All the best.
