There are some wrasses that have been known to eat them. Melanurus and six line but hteres no guarantee. Manual removal is the best move. If your colonies are mobile I would remove them and do some freshwater dips.
Zoa eating nudis are a nightmare and can be one of the hardest pests to irradicate

+1 on the yellow coris, best wrasse for the job IMO. Inspect each colony/frag very closely for egg sacks, you will need to scrape these off manually as dips/wrasses will not harm them.

How hard are these to see? I have a few zoa frags not opening and I'm kinda wondering if I have them. Were they pretty easy to see?
They can be tough to spot considering they color up depending upon the zoa colors they are eating. http://reefkeeping.com/issues/2005-05/rs/index.php

I've used a green coris wrasse and a melenarus wrasse in my zoanthid tank.
I currently have a leopard wrasse in my zoanthid tank now.
One way to get rid of adult nudi's is to do dips in FWE, at 4X the recommended dose in the instructions.
Doesn't hurt the zoanthids at all but kills the nudi's in seconds, and it is easier on the zoanthids because it is done in saltwater.

They can be dipped in freshwater and lugols, which is very effective also.
But after seeing how FWE works, I like it better.

They are known to take on the color and shape of the zoa they are eating. They are usually very small. The best way to ID them is if your zoa colony is closed up, they will look like some are partiaally open. They actuall mimiic the tentacles and color.
I found what I concidered the "queen bee" in my tank. This Mo was 3/4" long and pretty. I killed it, not knowing what it was at the time. I spotted this thing right before I started having problems with my zoas.
Book stores like Borders or Barnes and Noble, or a craft store, like Michaels. Look in the needlepoint section.

clear your messages #1 lol
and also you can see them at night on your zoas. Take a light and look closely at them and you will see them around the bases if you have them.

The best time to find them is right when your lights turn on, before the zoanthids open up. You have to look very carefully though as they are very hard to spot. Forget about manually removing them to keep them in check. I've done this for a year, there's an endless supply. It's a chicken and egg thing.
Yellow Wrasse is arriving today, hope he's hungry.:fish1:

That's the best image of one I've ever seen, probably good enough to identify. Why don't you post that over on the Sea Slug Forum & ask for an identification? Bill Rudman, who runs SSF, is always looking for more information on behavior & feeding & would be quite interested in seeing it. <www.seaslugforum.com>

I hate those things!!! I have been trying to get rid of them for about 3 months now. Sadly over half of my 58g tank are zoos and palys so fresh water dip is not really an option. I manually remove 2-3 adults a week. Any other solutions other than a wrass? My tank is already super stocked with corals and fish and I don't like the idea of more fish in my tank
