    I need urgent help. My green monti seems to be eaten by acro nudibranchs.

    It happened over night and is just getting worse.

    Looks alot worse than this now

    It was then recommended that I dip the coral. I did and found these guys in the container afterwards. I dipped again the following day with more found.

    just keep up the dipping up, should be a few days
    there is no other cure, except adding a wrasse

    the only way forward is dipping the corals every two days.. and cleaning the nudis off every day. take the monti out of the water and using a cloth wipe the nudis off. you will have to repeat this for few weeks as some nudis can hide in the sand near the monti. it is important to wipe the eggs off regulary.. eventually you will get rid of them. just remember that not seeing the nudis for few days or even weeks does not mean that they are gone but maybe there are eggs waiting to hatch.

    @Fraser W and @rigby and myself are still fighting the nudis.. cleaning cleaning them off manually off the coral is the most efficient method we found.. in fact I can say that I'm 95% sure I've managed to get rid of them in my tank.. although I have far less montis to clean than my friends

    also note that they love staghorn coral as well.. if you have any in your tank make sure you check them carefully. always look on the underside of the coral because that is where the nudis will lay their eggs and you will be able to spot them easily

    HUH??? Please substantiate. Unless you mean the branching montiporas... Staghorn.... guess theres a reason for scientific names.... A. cervicornisis what pops up when I use google..

    This article was published a few days after I lost a whole box of purple and superman montiporas back in the day... to these little vampires... Bring on the garlic, lol.... actually, bring out the garlic!!1 seriously.. Two Potential Molluscicides Useful Against Pest Aeolid Nudibranchs Common on Species of Montipora in Aquariums by Eric Borneman - Reefkeeping.com

    They are doing the rounds in Cape Town tanks at the moment too. Please don't blame the suppliers, when you buy a montipora, its an assosciated risk...

    I had the same problem with these nudi oaks, took all my montis out and quarantine them with coral dips every second day. Get yourself a yellow coris wrasse as a preventative measure, they are the nudis biggest enemy.

    This is what my Monti look like this morning :-( Would these nudis also eat Bali Green slimmer as I lost that two weeks ago?

    Consider moving that piece to quarantine, those nudis can jump from one coral to another

    Nudis diet is very specific and these will only eat montiporas, so something else caused your slimer to die.

    you are probably right and i have the name all wrong... the coral in the picture below is the one im referring to. perhaps you can help me ID this coral as ive been calling it a staghorn for a very long time but to be honest i dont know why. i know for a fact that the nudis love this coral as well as the plating monti and this is a small piece i managed to save and currently trying to nurse back to full glory

    quorantine is a very good idea and will give you the chance to easily monitor the coral every day and also they wont be able to hide in the sand. @rigby almost lost his encrusting montipora as well

    also remember that dipping will only kill the nudis and not the eggs.. thats why its important to wipe the underside of the coral regularly or where the nudis have laid eggs which sometimes can be near where they have been eating the corals flesh as well

    I took many pictures of the nudies in different stages of the cycle will post them just now and you will be able to find what to look for under the corals. . the only lay their eggs around where the flesh meets the skeleton of the monti.. and a sure sign you have an infestation is when tout see the edges of the monti paling or turning white small circular patches means a smaller colony of nudis and large straight recession means there are many nudies at work

    Thats a branching type of montipora. So the nudis will love that

    potassium permanganate worked for me..its cheap and effective..just be careful with your measurements when soaking coral..and don't add directly to tank..dip corals in separate container

    When it gets to coral ID, especially acropora and montipora spp, one really needs to have dead specimens on the one hand and Veron's books for a reference in the other....

    However, there are a few standouts, especially with the more abundant montis:

    This one is either a M. hirsuta or a M. Stellata.

    My bet would be the M. hirsuta, grows like a weed under the right conditions.
