Zoa spawning

My family was sitting around tonight and my daughter said "Dad, look at your corals!" My corals were squirting white fluid out the center of some polyps. It happened for about 10 minutes then stopped. By then the water was all milky. It took a few hours, but the system cleared the water.
Any idea what may have triggered it? I did add a Copper Banded Butterfly last Saturday and he has been nibbling at the zoas.
Thanks!
