Monti-eating nudibranchs?

Yeah you can see them. You should look in shady areas, they like to hide. You will most likey see the little legs, they almost look like extended polyps. hey will be right on edge of the dead spot where the is fleash for them to eat.
Good luck, if you have other Monti's I'd recommend you either remove the comtaminated one or the ones that are not comtaminated. They will eventually crawl over the rock to your other peices, it's as if they are following the scent to more food.

I don't have a nudi problem, anymore. I haven't seen one in a long, long time. My 6-line would love it if there where, though.
However, something else seems to be targeting my montis. I have sought information regarding this problem, several times, on this site. No one seems to be able to offer any advice, unfortunately.
Most of my digitatas and plating/whorling varieties have succumbed to something, but I can't seem to put my finger on it. They usually start slowly RTNing and eventually completely die.
All of my other corals continue to live and many, including, an acropora, continue to grow. I also have a pocillapora that seems happy go lucky, as well. Only the montis seem affected.
This has been going on for about 5 or 6 months without any problems for either the fish or any of the other corals. Strange.

Wouldn't a low Mg level affect the pocilliporas and acros, as well?
I will check it, though.
Thanks-Mike

What is the preffered method to raise a low Mg level?

i have tried most everything to kill these off myself, with no luck, radiant wrasse, yellow wrasse ect as well as most dips, even went a few months with no monti's and finally decided to re-stock my tank and poof out of no where got them again,
If you can remove the corals temporarily you can superglue over the eggs and it will trap them. This is how I got rid of mine. I superglued any nooks and crannies in the underside of my caps and manually removed any on the top faces. whenever I saw eggs I put a drop of superglue gel over them and trapped them. After a month or so I didn't see anymore. Lost a few mini colonies, but save most of my nice stuff.

Im fighting those blasted thing also, got my numbers way down over the last 2 months but still popping up here and their, Melve did you ever find any more of the Tetra Oomed, Im interested, I found after a water change put the Monti in the 5g bucket and blast the heck out of it with a turkey baster work good at blowing the eggs off tooth brush also, I just crushed some of the common caps, to much work for a coral that will grow back in 6 months
also found in my experience that they seam to like the spongodes best.

I have tried taking the eggs with a tooth brush but :
1) the eggs are very hard to get off even with this method.
2) you can only scrub egg clusters you can see and get through and in this monty (cup) there are alot of places which the eggs can hide from.
I have thrown 2 big colonies of Montipora Capricornis and 2 colonies of montipora digitata over this nudies :uzi:

I feel for you guys who have these in your display tank. I have three very small frags, the largest of which (after I trimmed it down) is about double the size of a quarter, and the other two could fit on a dime. These three tiny frags are in my QT and I STILL can't get rid of these little bastards. I've started looking at the frags under a strong magnifying glass and what looks to the naked eye to be little tiny dots turn out to be nudis. Unfortunately, the dips I've tried haven't been sufficiently effective and with my travel schedule, I can't stay on top of them. Every month or so I find a rice sized one and every week I see a half dozen very small nudis. You'd think in a small QT with such small frags this would be an easy battle. It's not.
I've tried (unsuccessfully):
1. trimming the frags, cutting away the outside bits and then crazy gluing them to a new frag plug. I thought this worked, but 3 weeks later I found a few more.
2. Dipping in Revive for 4 minutes. This does stun them which allows about 50% to be blown off, but it doesn't kill them. I put one of those blown off in a glass with fresh saltwater and it lived just fine.
3. Dipping in CoralRX for 10 minutes (4 treatments so far). This was recommended to me by the online vendor who sold me the infected frags at MACNA. CoralRX states that they "remove" rather than kill nudis. I'd say it's 50% effective, when you need 100%. Those that don't get blown off survive, as evidenced by putting one of the nudis in a glass and it continues to survive to this day. CoralRX at 10 minutes (as directed) was also very stressful to some LPS that were getting dipped at the same time, since they were in the QT.
4. Forget trying to do something with high salinity or making quick salinity changes. These buggers are TOUGH. I had several of them in a measuring cup with saltwater sitting on a table before I left for 17 days on a business trip. When I came back, a bit more than a third of the water had evaporated and the salinity was around 50 ppt. One nudi was fine the other was floating. I then dumped in fresh RODI to bring it down to 34 ppt and two days later they were both fine. I don't know about hypo-salinity.
5. I haven't fully tested how long it takes for them to starve, but 17 days without any montis to much on wasn't a problem for them.
These nudis are much tougher than any fish or coral.
Unless you use biological solutions, such as with certain wrasses, I don't know of a way to get rid of these guys. The problem with biological solutions is that you don't know for sure that you've eliminated them and it would be irresponsible to trade any frags with anyone.
Incidentally, I've got to say that I'm a bit disappointed in the vendor. I sent him emails right after MACNA and warned him that he was selling frags with monti eating nudis and his answer was that he didn't think he had any, but he'd dip his corals in CoralRX just to be sure. As I've seen in my own testing, that isn't nearly sufficiently effective to ensure that he isn't spreading them to other customers, who continue to this day buying corals from him and, presumably, then having to go through this hell themselves. I sympathize for the vendor, who would have much more trouble eliminating these from his stock than I'm having, and to stop selling would cost him a ton of money, but at the same time I would be furious if I bought some corals from him and had my tank infected even after he had been warned.
The big lesson for me is to always quarantine. Had I not quarantined, I'd be blissfully ignorant as these F*@#$ers were spreading in my display.
