Monti-eating nudibranchs?

Word is that Oomed will not work, didn't seem to have any advantage for me, and I still have a stash of it. I read over Tracie's article as well, but I think I seem to have heard that she is no longer convinced that Oomed has any effect (if you search around for some of the older threads on this I think you will find the same info). At a high enough concentration it will work as a dip, but I think there are better options. The chances of it working as a whole tank treatment is very low IMO. There was a thread a while back where Mitch Carl described the treatment with Levamisole HCl which does work on the Montipora eating nudis, and apparently will also work for Acropora eating flatworms. The treatment was summed up in this thread on the BRS site:

I found a place that sells the Levamisole HCl. While I don't have either the Montipora eating nudis or the Acropora eating flatworms, I would like to occasionally add a new frag without excessive fear. Therefore I have a bottle on the way. The stuff will not kill eggs, so quarantine of new frags is still required.

I did have the Montipora eating nudi's in a frag tank a few months back. I used the iodine treatment that Mark (Shallowaters) mentioned. I wanted to save a buck and not use Lugol's, so I did a calculation based on the % active iodine in Lugols and in Provodine Iodine available frome the drug store. I came up with a formula of using 1 ml/100ml of tank water in a bath for 3 minutes (based on Mitch Carl's recommendations of Lugol's dip). This did seem to work for me. I dipped each frag then blew it off extensively with a turkey baster before adding back to the tank (to make sure they all fell off). The iodine treatment is pretty harsh. I found that while most Montipora's did fine (4 colors of M. digitata, and 4 colors of M. caps [probably M. foliosa]), I did notice that some of my purple M. caps faired poorly several weeks later. The nudi's were gone, but the tissue was damaged too much, and some of these colonies regressed a lot. This might have been do to the fact that the purple M. caps were the ones that the nudi's seemed to always gravitate towards, so these saw several dips.
FWIW, I was successful in eradicating the Montipora eating nudis in my frag tank (have not seen any in about 5 weeks, and I've been checking), and was lucky that the nudi's never made it to my main system(s). I still don't really know how I aquired the nudi's in the first place since I do not recall taking any Montipora frags from anyone in a very long time.

Greg's Provodine Iodine treatment, with repeated applications, seems to be effective. It does not instantly kill hatched nudi's, but their grip is loosened and they either fall off or can be blown off as suggested.
Greg, now that you mentioned your frag tank, I'll publicly thank you and give you credit without suggesting you ever had bugs.
Seachem also suggests a high dose of ReefDip make work for nudibranchs - with the caveat that their recommnended doses are known to be safe for most corals and they are not recommending higher doses.

My corals are just too large to take out of the tank. So I have to siphon them off. My purple chromis' love to eat any free floating ones, but they will not pick them off the corals. I am really hoping to find a natural solution to this problem. What really annoys me is that the only coral that I have added in the past three months has been a blasto and I won that in a raffle......
One interesting thing I have noted with the ones that I have, they seem to be only going after my brown caps. They have not affected my orange, green, purple or any of the encrusting ones (Superman etc..) as of yet. Maybe they are saving them for a midnight snack. Bad humor, I know

Here you go.

I siphoned out about 200 last night from the frag tank. Man, they are everywhere. I'm mixing up some new saltwater now, so that I can dip, treat, and rinse, plus have water change water on hand.
I added 3 Small Tailed Pencil Wrasse (Pseudojuloides cerasinus) a few months ago and the nudis were gone in a couple of days. Have not seen any since. These wrasses are supposed to be difficult to care for but so for I have not had a problem. The Yellow Coris Wrasse (Halichoeres chrysus) are supposed to work too.

Thanks Mike. I just ordered two bottles from that link on Ebay while it was handy. I've never heard anyone ever refer to that type of wrasse. Since they are jumpers, it isn't exactly good for my frag tank but thanks for that additional option. I can get a Yellow Coris almost any day of the week, so that is another option. Right now that tank is fishless for a reason.
ctxmonitor - I had a few, then a few more, and then each group of them laid eggs and it is just out of hand. And yes, there are lots of monti frags in that tank. If I can't save them, I'll just cut my losses and restart with a fresh (better) setup, utilizing a sump and skimmer.

The problem I see with using fish is the Nudis stay hidden in the day and emerge at night so the fish are not out and about when the Nudis are. The bigger the colonies the more convoluted they will be with more nooks and crannies. The fish would help but I can't see them totally eliminating them. I don't imagine the Nudis evolved to be fish food.

While at the LFS tonight, the owner was showing me how one of his M. digitatas were bleaching from the core upward. He didn't know why it was dying, and I looked at it and saw the pests immediately.
We used some TMPCC and dipped the coral for about 10 minutes or so. I used a turkey baster to blast off the nudis, looked for eggs and found none, so the coral went back in the tank.

They are not interesting, at all. You are with them, or you are with me!

For me TMPCC hasnt seemed to work very well on the nudis. I only have 1 cap(new tank and the first monti i received had them so i am not putting any more in there, call it a monti nudi killing tank) I have gone in and pulled out the monti COUNTLESS times brushing them off with a tooth brush. I try to remove the eggs(they are hard to get off) by scraping them with something sharp.
I did 125% the recommended dose of TMPCC on the nudis i pulled ofF the monti in a measuring cup. The smaller ones died within 10 minutes, however an hour later the big boys were still moving. After 2 hours they were dead. Problem is they get in the crevices and lay those eggs where we cant see them.
Right now i am trying a weekly TMPCC dip on the affected frag. I will post my results in the next month.( i am doing it slowly as the monti is doing very well surpisingly, probably because i keep removing the nudis)
I WONDER IF THERE ARE MONTIPORA EATING NUDIBRANCH EATING NUDIBRANCHES?

The only fish really attack this barstards is Radiant Wrasse.
I had bad infestation a while back, this fish really helps w/ o ripping every montis in the tank., As long as u dont have any agresive fish in the tank that can attack this fish, so he can feel at home and comfortable and start working, you will be amaze, and watch this natural nudi preditor strike each one in the tank until U have no more.
The tank is nudi free until now..........thank god for this fish.

I used a toothbrush to brush off the eggs (in a bucket outside the tank!), superglue to "encase" the leftover monti's and the nudis and then a longer and stronger than normal lugols dip... I know that lugols doesn't kill them but it definitely helped a little being that I don't have them anymore and I battled them for nearly a year losing most of my best pieces before I went overkill as described above... I also added a small yellow coris wrasse, it seems that everything I did was enough because I've been "clean" now for nearly 6 monthes . GOOD LUCK These things suck.. I have had every aquarium pest mentioned on this site it seems and the hardest to get rid of were the monti nudi's...
