Zoanthid eating nudibranch

[carlos413]

I just found one of these on one of my zoa colonies. I noticed that for the past four weeks this colony had most of the polyps closed. After further inspection and some goggling yup I got one. I can remove him manually but how do I know if I got them all? Could I use a coral dip to rid them off my colonies?

fresh water works if you can get them out, just look for eggs

Are there alot of them, if so i would do a freshwater dip. If its only one or two, just pluck them off with some tweezers. If there is eggs do a freshwater dip.

You will never know if there is only one or two... you will definitely miss some. The eggs will not come off with freshwater dip. They are extremely sticky and have to be removed manually with something like tweezers.
I use FWE and this is what I do to fight these guys if the zoa rocks can be removed.

• 3 - 4 cups of water from your QT/display tank. (enough to cover the coral. If you need more than 4 cups, double the recipe).
• Add 4 drops of Flat Worm Exit (FWE).
• Place the coral in the dip for 15 minutes, turn the coral upside down and shake vigourously for several minutes towards the end of the time frame.
  Place the coral in some freshly removed SW from the QT/display and place the coral in the unmedicated water for 15 more minutes, again shaking towards the end.
  Place the coral back in the tank in an area of high flow to disperse any mucous buildup.
  Redip in 2 weeks to target any critters that hatched since your last dip.

I manually removed four of these things today. I will be getting some kind of coral dip this weekend, and dipping my zoa’s. Will these things only go after zoa’s or are all corals at risk?
