Zoa Eating nudi?

[Bam327]

I haven’t seen them take out a polyp yet but they sure are making my colonies mad where they show up. This was the biggest, and about the 6th one I’ve plucked out. What are my options? I have a 6 line that apparently won’t touch these. I have flatworm exit on hand and I can try a 4x dose but I’m worried about my inverts and only want to use that if I have to.

Awww man- thats a lot and likely more. All you can really do is keep pulling them as you see them but I must warn you. . . . . With these you've seen thius far- there are likely eggs and they have to be blotted off.

Will a wrasse help keep the numbers down?

I forgot to mention that these fluoresce under blues and make them pretty easy to spot.
My 6 line isn’t eating them and there’s no way to add another wrasse with my 6 line already there.

Can you explain what you mean by blotted off? I think there was a hatch because the previous ones I saw were all super tiny. Like I almost couldn’t even tell it was a nudi because it was so small. I don’t think I’m at an infestation point yet. But I have a lot of zoo’s I need to protect

These are the eggs which are laid in a letter "C" or circular pattern:

The eggs cant be treated with dip which has no effect on them. You have to take a damp paper towel and blot them off. Its easiest to see the eggs under heavy blue actinics and are usually laid on the stalks of the zoas

I've used Flat Worm Exit as a dip and as a whole tank treatment.
The main issue I found with treating the whole tank was the effect on the inverts most specifically the mini brittle stars.
My zoanthid dominated tank seemed to have a over abundance of mini brittle stars and it seemed like there was more than a 50% death rate with them. After adding FWE to the tank they seemed to gather in a big ball and most died.
I would go through the tank before the treatment and remove as many of the hermits and snails as I could find, so I'm not really sure how they would react.
Most of the time when I used it as a dip I would use 4-5 drops in a quart of tank water and place the colony in for roughly 2 minutes.
Sometimes I would see a nudibranch fall/float off the colony and you could actually see the nudibranch disintegrate. Just fall apart. So satisfying.

There used to be a web page that detailed the FWE use, but I haven't seen it in a few years.
