What could this be???

I went through my 220 Gallon tank tonight with a flashlight, and saw a jelly like mass that looked liked it was filled with eggs. It was about 1.5" - 2" around, and the egg like things were all white. As soon as the mass floated infront of on of my returns, it just brok apart,and the "eggs" went drifting all over the tank. There is a Yellow Tang, an Orange shoulder tang, a cin. clown, and a cleaner shrimp in the tank.

Any Idea what this mas could have been?
