I need to let anyone who has gotten frags from me in the past to be aware that I just found a couple of what I belive are monti-eating nudibranches on a couple corals of mine. I forgot to turn my heater back on last night and in the process of trying to determine what was wrong with the tank when I first woke up I discovered the nudis on the underside of both my nodulating green cap and my purple poylp cap. I only found two, but I'm sure there are more. I'm off to the store to find a dip for them. I just really felt to the need to let anyone who has gotten any frags from me know. I'm not sure as to how long they have been in the tank, as I haven't added any new monti's since Dec/Jan so if anyone in the past has gotten anything from me please please look to make sure you didn't get any.
Warning!! Found some nudi's today

We had a guy whose helped alot of people with zoa eating nudi's. Dont know if montipora nudi's are tougher but he recommended FW dips. Iodine dips are meant to aid damaged tissue and not so much as a parasitic, although its been recommended alot in the past, but more of a wives tale and spread fast because its been uncontested for the most part.

Montipora doesn't do too well with fw dip though. You can do maybe about 30 seconds, maybe 45. The coral will slime and be waaay stressed. I heard about people who went over a minute on the dip, and they lost all their corals.
Best to move all your monti to a separate system and inspect them daily for nudis. Keep removing any that you find, and keep them in quarantine until you are sure there are no more. Look for egg masses too. You can toothbrush them off in a separate container of sw.
Good luck!

Hey, how's the eel doing?
David-
When I had them, what I did was a FW dip for 20 seconds. While in the FW I swished the coral some to help get them off. I then moved the coral into a bucket of tank water and gently scrubbed it with a real soft tooth brush. I did this every 10 day for 3 treatments. I didn't have any sign ofthem for over a year, now I have a reinfestation...but in another tank.
20 seconds may not be long enough to kill them, but I feel that it is long enough that they stress and let go. It's also a little less stressful on the coral.
I understand that the larvae have a free swimming stage. You could also try running UV or ozone to help kill them at that stage.

Marc, pm'd.
David,
The article talks about Tropic Marin Oomed working well to kill the nudis. I think I read elsewhere about people not being able to get that in the U.S. anymore.
I did see an Australian company that would ship overseas. Might be worth it to make their minimum order to have it shipped. I think it is available in Germany and Italy also.
The active ingredient is supposed to be quinine hydrochloride. Might be able to find other meds containing that. Malaria pills anybody?
Greenex is supposed to be malachite green and quinine hydrochloride. Still Googling info.
Anybody want to jump in and help Google some leads and info on concentration of active ingredient in the various meds, and availability of Oomed, Greenex, or other alternative?

Ok, don't laugh....
Cursory info here... tonic water like Schweppes, contains something like 70-100mg of quinine per liter.
According to http://www.pets-warehouse.com/Fishmed2.htm
Quinine is use for ich treatment at the rates below:
30 mg/L for 1 hour daily for 3 days
10 mg/L for 3 days, continuous
Is Oomed dosed at those rates?
Can we do coral dips with sw made from defizzed tonic water???

Article in Reefkeeping magazine indicates that Oomed has more than one active ingredient. Supposed to contain Aminoacridine also.

Ok, found this on Tetra's German site... they won't list it on the English version of their site.
http://www.tetra.de/doc/doc_downloa...076A019D4C52C349E4B&o_file_id=340&o_lang_id=1
Label info from their MarinOomed.
Apparently the MarinOomed isn't availble to U.S. anymore because the aminoacridine is mutagenic. Wonder if it's available in other meds or from a chemical supplier.
My Chem is rusty, and I don't read German, so I'm faking it....
Looks like it has the quinine hydrochloride, the aminoacridine, Hexamethylpararosanilin(crystal violet anti fungal), and benzyl dodecyl-bis-(2-hydroxyethyl) ammonium chloride (anti microbial).
Can figure out the effective ppm based on the weights and dosing rates. For killing nudis, the anti fungal and anti microbial may not be necessary.

Ok, Oomed has .5g quinine/100ml med.
Original Reeffarmers treatment was the fish only dosage of 5ml/12.5l tank water(.4ml per liter). That works out to 2mg quinine hydrochloride per liter of water. That was a 5 minute dip.
Revised Reeffarmers treatment was .75ml Oomed per liter. That works out to 3.75mg quinine per liter of tank water. The dip was for 10 min. Followed by a Lugol's dip.
If quinine is the ingredient effective against the nudis, tonic water at the 50ml of tonic water to just under a liter of tank water would make a quinine dip containing 3.5-5mg of the med.
I need to try this on some monti nudis! Someone help test this out!
Gonna read up more on quinine and aminoacridine. Maybe I get to have a nudi dip named after me

If we don't find info indicating that the aminoacridine is the active ingredient against nudis, can we get some volunteers to test this tonic water dip on some sacrificial cap frags?
Can someone round up some test nudis? Even zoa nudis, just for the heck of it, though their biology may be different. I know where I can get hold of some zoa nudis in the afternoon too.
I have some plain old brown cap frags that I'll test tomorrow.
Sorry for the crazy postings here. I'm super intrigued by this, and I'm just posting as I track down bits and pieces, in the hopes that some others will jump in to help.

Gresham, thanks for the pointer. I really appreciate that!
Ok, gonna be out of the house until late afternoon.
Did see that monti and zoa nudi are both aeolid. Also ran across some nasty info about burrowing paly nudi... yikes!
The quinine appears to be one of the nastier meds as far as reefs go... my impression from poking around wetwebmedia.
Here's an interesting url:
http://www.inchem.org/documents/jecfa/jeceval/jec_1949.htm
Someone want to help do some test dips w/ ~50ml tonic water to a quart of tank water? Sugar free, no lemon, or whatever... gotta see what's at the store. Uh, no gin and tonic for the tank now, unless you are combining it w/ that ethanol dosing idea
