Monti-eating nudibranchs?

I've begun my battle with these buggers today. I got the adults off with lugol's dip but there are still hundreds of eggs on my montipoa confusa. The super glue idea sounds plausible.
Also, has anyone else tried the boiling water being squirted on the eggs?
I believe that they do multiply similar to starfish whereas if you cut them each piece would form a new nasty:hmm5:
 
Just discovered these guys munching away at one of my montis.
Tropic Marin Pro Coral Cure sure does something to them. As soon as I added the stuff to the container I was holding the Monti in, the little buggers were on the run. Was able to blow them off with a turkey baster after that.
I put the monti in a quarantine tank....well see how it turns out

lots of deeps will do the work with the adults, none will do the work on the eggs :uzi:
 
A potassium permangenate dip is supposed to kill both the adults and eggs. I have been trying to tweaser them off for about a month and they just hop from one coral to another so I have KMnO4 on its way from ebay. Ill update in a few weeks and hopefully they will be gone, have been lucky and haven't lost one yet.
 
Im really happy I stopped to take a look at this thread. I pulled one out no knowing what it was. After reading through I checked my montis again and found three more. All on a recent purchase. Im hoping they have not spread out to other pieces.

Anyone have luck with the Coris wrasse?

Absolutely. I had monti eating nudis destroying a few corals in my old tank. I tried dipping, manual removal, and a 6-line. All slowed them down a little but none took them out completely.

Enter the yellow coris wrasse.... After all esle basically failed I decided to pick up another wrasse. Luckily, the one my LFS had in stock was a yellow coris. I took it home, put it in my tank, and within a few days all visible signs of monti eating nudis was gone!

I've been through a few different tanks since then, but still kept frags of some of the corals that once had monti eating nudis. I've also kept a yellow coris ever since and have NEVER seen a trace of the little bastages. The yellow coris may not be the prettiest, but they sure are beneficial.
 
If the piece can be pulled out of the tank, i rinse free all adults in a bucket and superglue all of the dead areas, especially the undersides or crevices where eggs can be attached.
after watching for several weeks you can stomp em out in most cases.
 
ive got them too:mad2:
its amazing how quikly they reproduce. I keep siphoning them out because I dont want to remove the coral because its encrusting to the rock now.

I did some siphoning of the little killers and noticed that they can be as tiny as a poppy seed, so small you would never see them on the coral until they get big and by the time they are big enough to see, they have already laid eggs. Its a never ending nightmare.:furious:

I got rid of my Acropora/monti eating nudibranchs since my post. I'm not sure how, but I added a sixline and manually hunted for them at night for about a week. I also added more hermit crabs since my last post. Im not sure what did it but probably a combination of all the above. I haven't seen a nudibranch for two weeks and my corals don't have any bitemarks.

We just discovered we have these little buggers :(

What is the potassium permanganate concentration that you used and was it effective?

Between the melanurus, yellow coris, and radiant wrasse, which is more effective? Has anyone ever tried the scarlet pin stripe wrasse?

Thanks in advance for your opinions.
 
Freaking hate these things. Thought I got rid of them and as soon as my wrasses died from a nasty red tide (cyano), they are back! Found some munching on my undata and also a green digi. I have 11 different types of Montis which they all our my favs, so I ordered two different wrasses now that my tank is healthier.

I've come up to the conclusion you can not just soak them in a dip and blast them off and all is good. They must lay eggs in the coral tissue itself and always come back. I always end up removing the best section top part of the monti and starting the frag over again. Seems to be a never ending battle.

Fingers crossed the wrasses will save the day again, I went with a bluestreak and a yellow coris. Pray for my monti's this sucks :(
 
2 yellow coirs wrasse's and nightly checking of the corals seems to be working for me. But still to early to declare victory. I'm able to lift each *** up and inspect nightly as this is my frag tank.

I've noticed they eat out a section on top of the monti and lay eggs at that spot, at least so far.

Not sure if the hermit crabs are helping?
