Those eggs are from Nudis alright. They will lay them on anything, but prefer zoanthids.

The eggs are impossible to kill, neither chemicals nor fish will get them. All you can do is hope that whatever way you find to fight them gets any freshly hatched nudis. This means that any treat ment you do must be repeated.

The incubation period of the eggs is about 3-4 days; baby nudis reach egg-laying stage in about 7-10 days. That means to be completely sure you've won, you must treat your tank for at least 14 days.

Options:

1. Flatworm Exit seems to kill nudis when applied in ver high dosages. (10x recommended) That can get pricey. If you go that route, dose it 3 times within the 2 weeks.

2. Yellow Coris Wrasses tend to eat nudis much more readily than the Sea Grass Wrasse.

3. Vigilantly observe your zos multiple times a day and remove any nudis (with syringe) and eggs (fingernail). After a few weeks you should see results.

4. Place all (ALL!!!) your zos in a small quarantine tank and treat them in there for a few weeks. Any nudis that are left or hatch in your reef will starve to death eventually. You can then repopulate your tank with your zos, assuming they are completely clean.
 
5. There is mention of Nudis that eat ZoNudis in various online scientific studies. I could not find the particular nudis for sale anywhere so gave up that idea as a deadend. Unfortunately, I don't have either the articles or the name of that nudi available anymore. A good long search on the web might help you. (there is a webpage just for nudis)
 
Are you talking about the spiral things?? If so they are Spirorbidae worms. Harmless filter feeders. Nudi eggs will be around the colonies.

darn i new i should of checked in here first.
after a long days work i come home and sit down and check whats new on rc.5 mins turn to 15 then to a hour and before i know it im wodering what happened to the time.

we'll today after posting last night i was convinced it was the nudi eggs so after work i had my energy drink and started to pull all my zoos out and fresh water dip them and put them in a seperate tank soo these "eggs can hatch and simply starve to death.(main tank)

and really watch the zoos in a seperate tank.well better safe then sorry right.

should i put on a hang on filter on the tank.it a 10 gal with zoo's only i threw in a cople of crabs to oick at the zoos.i have a pc light on it 50/50/s with blue atinics.
 
Just keep dipping the colonies periodically. And again. Those are not nudibranch eggs on your tank. The nudi eggs I have seen are small pearly orbs in clusters on zoo colonies. I'm sure there are other varieties than what I have had. Mine were the "eat only the expensive blue zooanthids" variety of nudi.
"Ooooohhhh! Consarn it! I hates nudis!"
 
Those are not Spirorbidae worms you've got on the glass there, they are too translucent. Try getting a closer shot of them, but they sure look like nudi eggs.

I'll send you a million pics of nudi eggs that are NOT on the polyps. If they only laid them on polyps, no one would have a problem and they'd be much easier to eradicate.

P.S. They also lay them on rock.
 
I had those all over my FOWLR and why would a nudi be in there nothing to eat and multiply. If you look at the link that msman posted you can the individual eggs on the polyps. Albeit that the first pic is not the best(no offense) but you see the tube leading around. JMO
 
well ive been checkin 24/7 with a flash light to see if theres ant differance but none yet ill get a better pic also thery are on some of my rock.what a a pain
 
yeah, I was going to say they're probably some type of egg, just not zoa eating nudis. Those nudi egg sacs are a PITA to remove from colonies. Talk about tedious work.
 
kryppy awesome pictures. Did you use a microscope or camera? oh, by the way, if they were nudi eggs, which I don't think they are, you would definately see some nudis roaming around. But in case I am wrong, manual removal works the best, and with a little determination, eventually win out, because you know where they are headed for lunch. Just nab them along with there eggs as they munch.
 
ok im convinced its not eggs but any ideas what it is ??if its good or bad??there not slimy .ther kind of hard to get off the glass .pretty hard had to you my nail.also take a loook at the 4th pic what is that black crap.its slimy

no those are NOT nudi eggs they are Spirorbidae worms as already stated, they are perfectly reef safe and harmless filter feeders
