I have a mated pair of "nemos".... Fascinating fish, the clown.
It is born with the genetics to develop into a male or female as it matures and sees a need for one or the other. Moreover, it can change its sex to further the species if need be.
I put five 1 inch juveniles in my tank three years ago. The dominanant clown killed 3 by scaring them and badgering them when food was offered to the tank inhabitants, leaving one to be the mate. The dominant clown always becomes the larger female.
I hope to see them spawn this year. They're certainly old enough for it, but my tank parameters are less than ideal at times and that can mess up their ability to reproduce.
Of course, when the eggs hatch at 2 am one morning, I will be home asleep in bed and the fry will be eaten by other fish or get caught in the filtration and die. I ain't losing any sleep to catch tiny clown fish and try to raise them in another tank, that's for sure! I'll leave that to the professionals.
