Zoa eating Nudis

Spyder · Jan 28, 2010

The title says it all. I have removed two of them so far I am willing to bet there are more that I haven't seen yet, so the question is how do I kill them?

This is the first of the two that I busted.

wow. I have never seen one before. How big is that?

Ricky,

I'd go with a green or yellow coris wrasse. I had them and added a green CR and haven't seen one yet and my Zoas are totally over the polyp muched look. Yay!

Manual removal, check all polyps for egg masses from the nudis ( scrape them off ) , DIP your frags and colonies. add a predatory IE' wrasse like YC/GC/or lined wrasses.

Ricky,

The ones I found are around 1mm. Look at the apostrophe on your keyboard, thats about how big they are.

I would love to do that but I have a few concerns, I only have a 30 gallon tank and I already have 5 fish in it, 1 royal gramma, 2 percula clowns, and 2 domino damsels. Both the clowns and the damsels are breeding so they are already on edge all the time. I am worried that the tank will be over crowded and fights will ensue if I add the wrasse.

Still think the wrasse would be the way to go?

I looked for eggs and can't see any but I will look again tonight.
What do you recommend I dip them in and how do you do it?

there small fish i dont think u would have a problem

I had some in my tank that I believe came in on some zoa frags I got from a swap. It was when I first started up my tank so I didnt dip them. I noticed the zen's one night while peering into the tank with a flashlight. After some research found out what they were and started manually removing them. I checked all my zoas every night for about 3 weeks and would pluck them off with some tweezers, slowly I started seeing less and less and now I havent seen one of those until you put up that photo. Which is a great photo given how small they are.

Lugols, TMPCC, Revive, CoralRx??? and others

I bought some with nudis once (on purpose). I treated them by freshwater/Lugols dips. Using a bright light, I inspected them, using toothpicks to move polyps around to be able to look at the base of the polyps. I found most of the egg masses there. Fun fun.

I'd love to take some nudis from you, if you haven't disposed of them yet. I've been looking for pests of all types for a while, have had some responses, but no luck yet.

I had them years ago, got so ****** off I dipped them all in fresh RO water for 30 mins...the only ones I did not do that to were my LE's, at the time there were only a few.

Good luck, they are not as bad as the Monti eating ones, they are super duper bad.

I still have the two I pulled out, I don't know how long they live with no food (they have been without for about 28 hours an of the time of this post). If you really want them I suppose we could work something out, I don't want anything for them.

650-IS350 · Jan 29, 2010

Dips won't do anything to the egg mass, only will affect newly hatched, juveniles and adults. which is why you have to inspect all frags/colonies for the egg mass to manually remove via scrapping or pulling off.

I fought them for a LONG time. Iodine based dips do nothing. Revive works but was not available during my battle. You can never get all of the eggs. I got rid of mine by getting a small yellow wrasse.

ca2or · Jan 29, 2010

The only fish I would recommend is a Melanarus Wrasse....he is just as effecient as the six-line without all the aggression. Very good fish to own.

Spyder · Jan 29, 2010

I went over the colony last night looking for eggs, I'm not sure if I found any but if it looked like an egg/eggs I snatched it up.
Its easy enough for me to get the colony out so I will pull it out once a week and go over it as long as it seems like it is handling it OK.

I'm gonna check at my LFS about the wrasse but that one will have to pass "will my wife allow it" test.

Thanks for the links. After going over them I can say that I didn't see any eggs but I will still check them again just to be sure.
One question about the FWE, while I was going over the Zoas I found a brittle star hiding in the colony, will the FWE kill those too. I'd rather not kill the star but if it come to the point of star VS Zoas then I will have no issue exterminating it as well if I can't find it again for removal.
