After several years of having a happy tank, the Asterina stars have taken a liking to my zoa colonies. I've never had a problem before until just recently. I don't know exactly what caused them to start eating them but here are some pics of the Asterinas on the frags themselves and the damage they can do in a short amount of time. And, yes, I added a Harlquin shrimp today.

This rock was completely covered with well over 100 polyps...

A bad picture of dead/dying polyps...

My Tubs Blue with a line from the bottom to the point where I pulled the star off of it...
