Problem with Zoas

[Time to Reef]

My zoas have not been happy for approx. 10 days now. Most of them were put in the tank two weeks ago. Most of them opened up and extended with the exception of one. However the last 10 days they have not been happy. I notice that some very small critters (have to look very closely) are on the ones that are not opening. These critters have colour (mostly bright orange or yellow) and appear to have two feelers at the head. Could it be these are "bad" nudibranches. How does one identify the "bad" ones?? and more importantly can they be eradicated??

Ok they look like the critter in "Avi"s reply. Now what. I have read some of the posts in the zoo forum here - getting a nudi eating wrasse. If so, what would be the best choice for a 34 gal tank. It will be the only wrasse in the tank. What about dipping the rocks. They are small rocks and easy to get at.

Try this link. I think I would dip them before any pests, if you have them, get out of control.
