Yea, Look for eggs too. They look like little white spirals, about as small as a pencil eraser. they are usually attached to the stalk of polyps. If you find them scrape them off with a dull needle, the do a FW dip.
Good Luck!!!
Good Luck!!!
I had some come in on some colonies from LiveAquaria.com even after a fresh water dip, with lugols and FWE they surived (or the eggs did) a few weeks later they hatched out and started back in... these colonies are now in QT and have been treated with FWE again and I will wait a few weeks.
I think the key to these is getting the eggs... the hatched ones are easy to kill with the fresh water but the eggs are hardy and will survive so pick them all off.
Luckily they were limited to those colonies and I haven't spotted them in the others.

Mucho... your posts have helped me quite a bit in the past... but I have a few questions for you on these things.
How long do the eggs take to hatch out?
Can nudis spread by taking to the sand or are they mostly surface animals (rock and glass hard surfaces)?
Do they only lay eggs on the polyps or do they do so in the rock as well?

Thanks for all the words or encouragement.......I did a quick FW dip on all the smaller frags and colonies. Unfortunely there were about 6 more. I also found (and removed) 2 sets of eggs. I am actually just starting to add zoos/palys to my tank, so access to the frags are easy. Hopefully I found them in time. I did do a FW dip before adding these to my tank. Maybe I didn't get all the eggs........
"How long do the eggs take to hatch out?"
DaveJ, I have tried and tried to get a number that was consistent, but the range I came up with was a 3 to 7 day incubation period. That is not set in stone, so I stand corrected. I have been trying to get a hold of some nice size nudis but now I can't find a single one in a store anymore. I guess that's a good thing.
Can nudis spread by taking to the sand or are they mostly surface animals (rock and glass hard surfaces)?
Yes, not only will they migrate across the sand, they will travel via the glass and on other rocks. I will go even further to say this, as I have been trying to prepare an article to write but I'm simply too busy in my personal life to getting around to it. So here goes, nudibranch can and will hide in a fine sandy substrata. My buddy was doing some basic tank maint and found one alive and moving a full inch beneath the surface of the sand. That is scary to know. Whatever method you use to eradicate nudis, make sure it is thorough. Even after you have dipped and treated your tank and you have been nudi free for a week, you must still flick your actinics on in the middle of the night and randomly dip rocks just to be sure. Nudis will hide on/in rock holes and crevices without zoas on them. This means they can hide behind your tank and emerge and continue to devastate long after you thought you have killed/removed them all.
Do they only lay eggs on the polyps or do they do so in the rock as well?
When I had them, I found them literally everywhere. On the side of polyps, on the crown of a retracted polyp, on rocks, on the glass, everywhere. This is why it is so important to extend your treatments even after no visible signs of them remain. Just be sure to turn on your actinics and check for whitish egg sacks that will be illuminated by the actinics. With everything retracted, you can see and remove an awful this way. Keep in mind the sacks are sticky, so using a dedicated set of tweezers will works wonders to remove them.
Sorry to be so longwinded.

Thanks for the info.... that is not very good news. So far I have not hand any spread into other parts of the tank, the zoos that I had mine in are now isolated in another tank (QT) but the colonies on the other side of the tank have shown no signs of any problems at all. Any idea how long they can survive without a food source? I assume they are obligate feeders, but is that a known fact or just an assumption?

Best way is to just dose them in the QT with FWE ( FLAT WORM EXIT ) every couple of days, Like mucho said 3-7 day hatching period.. to kill any new nudi that have hatched that you did not find...
Now that I have the famed NucGreens/PurpleDeaths/BlanePerun PPE's.. I am no longer taking chances and have a QT...
a $40-$50 10 gallon Qt full set up is a cheap price to pay considering how much you can loose by those thing running rampant in your tank...
A good watchdog like most wrasses can be... they eat tiny snails , some FW's and other pests.
