I was checking out my tank tonight about two hours after lights out and I saw one of my tuxedo urchins up on one of my gorgonians.
I've had two gorgonians for about a month now and they were looking great and even had noticeable new growth. Then about a week ago I started seeing less polyps and brown stringy stuff on them. In fact I moved the other gorg this morning because I thought it may have grown too close to a pectinia colony but as you can see there isn't much around this one.
I added two tuxedo urchins about the same time the gorgs got unhappy. Is this normal for urchins to eat gorgs or maybe it's just cleaning off the brown stringy stuff? Any ideas if I should or could do anything?
