pair of clowns

is there any way to tell if my clowns will end up a breeding pair ????? my clowns have took host in the corner of my tank under my wave maker they are very peaceful and the larger one of the 2 keeps doing some kind of crazy dance its amusing to watch but was just woundering if there is any way to tell if they could breed in my tank ????
Give them some time, they'll eventually pair up, and become a mated pair. The dancing/shaking you're observing is the one clown becoming submissive to the other one.
