I just discovered yesterday that I also have a nudi problem. I haven't added a new coral in probably 6 months.
For the last few weeks, I'd noticed most of my zoos staying closed all the time and last night I moved a frag of green zoas to a new location and noticed what appeared to be a new bright red zoa had mysteriously popped up right in the middle! Sweet! I completed my maintenance and re-checked the colony, only to find the new red one had moved! Closer inspection ( and a pair of tweezers) and it was a nudi.
My pride quickly turned to horror as I put 2 and 2 together, immediately finding about a dozen more all over. I had a Halichoeres Melanurus for the last couple years that died a couple months ago, so I can assume he was keeping the population in check the whole time, but never erradicating them, and now the population is exploding with no predation.
I'm wondering if anyone else has noticed population bounce back?
That wrasse also ate flatworms, feather dusters, bristle worms, and mini brittle stars, so it was already kind of a love/hate relationship we had going.

Me and adin (head mod a www.nano-reef.com) syphoned out 2 nudi's from my 7 gal mini bow (stop laughing please) as well as 20 flatworms.
I have a colony of Rah's Eye zoas that were shriveling up an noticed and believed it may have been the flatworms.
We syphoned out about a 1/2 gallon. we then placed 3 drops of flatworm exit into the container and after 10-20 minutes the flatworms and nudis wer dead
Ofcourse this was way above the recommended dosage.
I dosed my 7 gal with 6 drops and low and behold, found two very much alive nudi's 3 days later munching on my Rah's Eye zoa's.
(They were the same color as the zoa's they were munching on) I had around 30-40 polyps and I think i have maybe 5 that are now going to survive. I think flatworm exit will work but dosage may have to be increased which may risk other critters in the tank....
Any info on dosing recommendations for flatworm exit without causing collateral damage?

Sorry for hijacking this thread, but FYI.... i put in 7 drops of flatworm exit into my 7 gallon last night and examined a nubi that was about 1/4 inches long. After 10 minutes i siphoned him out with some additional water and examed him. 1 hour 30 minutes later, nubi was still alive I guess i have to use more flatworm exit but am afraid to overdose.......

They are very small shrimplike creatures that look like bugs in your tank.... They help to clean things overall and are an excellent food source for your fish and other foraging life. In general a very important part of your closed ecosystem.

Thanks man. I have been fighting the nudis for a couple of months. The dips have worked out fine. I am no longer seeing the nudis or egg sacs like i had. I ordered a seagrass from blue zoo but he did'nt survive. I have a cleaner wrasse and a lubbock which are hunting through the zoos, pretty sure they are eating the small ones. I want to add a few more predators to finish them off. Thanks Mike
I have a couple rocks in a 20 gallon with 4 types of zoos. These nudibranchs are living on them, but the population remains small because I have some unusual worms that hunt them down. The worm is grey with black patches. These worms are at least 3-4 cm long and have a circular mouth that opens wider than the body. The worm reaches up between zooanthid polyps to grab nudibranchs off the tops and eat them. The zoos continue to grow and divide and none have died despite having the nudibranchs on them for about a year.

Very very pretty pictures...
Awesome even
BUT the eggs will survive the dip....then the nudis come back and infest the rest of your $$$$ colonies you need an Obsessive Compulsive Sea Grass Wrass! I fought infestation forever, tryed everything... He came along and is like an evil nudibranch TERMINATOR ... Never have seen another nudi!

Yeah i read the thread, but i don't really have a lot of zoos right now, so dipping is not that bad. I can dip every week if i have to, that is if i don't get lazy, lol.
I just didn't like the fact that the wrasse also preyed on snails, crabs and such. I would hate to lose my cleaner shrimp pair. For now i will continue to dip weekly until the eggs hatch. With enough dibs, i should be able to get rid of them.
If i had a tank full of zoos, the wrasse is the way to go. But for me right now, it's easier to just dip. Thanks though.
This is a gross picture, but this is what happens to them when you hit them with flatworm exit. It's like they explode. Pretty gross!

Ya I had a BIG tank of zoos
WOW, I have to give you some props, those are the best pics of eggs and nudis that I have ever seen. Great job and glad you posted them.
FWE does not work on all nudis. That's a given from so many reefers I have spoken with. It seems that there are more than one type of these horrible nudis and unless you have the type that succumbs with FWE, all other preventive measures should be exercised.
Has anyone had greet success using the SGW for nudi eradication?
Mucho

As I listed above... my SGW totally solved my entire infestation within a day or two.. NOTHING else had worked... anyone who has large amounts of Zoos really should have one
