One of my zoanthid colonies were dying off so I inspected them closer and noticed a bunch of these on many of them. I'm guessing they are zoa eating nudibranches.
What are you doing to exterminate these ugly guys?
I picked up a butterflyflish. They are on some of the lower zoanthids and we can't really dip the whole tank so we're taking the biological weapon road.
Is it working?
We'll see, the bigger concern is the fish eating the soft corals long term. So far so good though. We've been pre-occupied with the stuff outside the tank =)
