Nudi eggs?

[crew33]

Noticed a Nudi in the store I bought some zoas from. They did a fresh water dip for me their, but said it wouldn't get rid of any eggs.

So my question is what do the eggs look like? And how do I get rid of them if there are any? These are blue zoos and I realy want these babies to live. So any advice would be appreciated.

Cheers

The egg ribbons are small white spirals.

[crew33]

Any Pics?

How do you get rid of them, If I have some?

thanks

Wow!! Thanks for the quick reply.

I realy enjoy this forum for its information and the great pics of everyones zoos.

I didn't care much about zoos at first but now I must say I'm addicted.

Thanks again for your help.

[Auryn]

thanks for posting that pic of nudi eggs
id read a dozen descriptions but a picture really is worth a thousand words

[crew33]

Ya I agree. If it was not for that picture I would not have known that I do in fact have some eggs.

So, for my next question. Is it as simple as scraping them off or is there a certain way to rid them?

Sorry to be a pest.

Thanks again!!!!

[mfinn]

About the only way is to scrape them off or pick them off with tweezers

[bobafett]

Not tring to be rude but why would you buy a colony that had visible signs of nudi infestation?

Some times 'pretty' beats 'smarts.' Seriously. I know I've taken risks before on a piece that was in trouble simply because the chance of saving something really eye-catching would be worth the risk.

Besides, at least this won't be a surprise. He knows they are there and can react accordingy; instead of unwittingly introducing something and then wondering months later what happened. ;)

[crew33]

Well Two words for ya........ BLUE ZOOS.............. and the price was right.

No...... actually what happened was I knew about the nudis just never seen their eggs before. So this post was about "what do nudi eggs look like"? Just in case.
Hence the lovely pic we all have now to I.D. the little buggers. (by the way thanks for the pic )

The zoos went into QT after being dipped then re- dipped.

Man these things are addicting!!!!!!

When will it ever stop ??????????

To all who helped ........thank you!!!!!

Nice Pic.of those little B-sterds!
Now I Know!

[swannL11]

I hate fresh water dips...be careful even 30 - 45 sec dips can melt those precious zoas

[swannL11]

Has anyone had any luck using quinine or flat worm exit to treat for nudi's?

[ezcompany]

fwe won't work for nudis. fw i found is the best.
actually zoas are very good with fw dips. its the sps that can't handle them.
also remember that nudi eggs can be CLEAR, at least that was the case with me. i am guessing this depends on the development stages of the larvae.

[wentreefgirl]

There is new luck on the acro board with prazi pro and nudis. Go check for details. I guess borneman and others are trying to tweak the dosage.

[ellisz]

I have used a old tooth brush to scrape the eggs off. Then just rinse in the dip water. Tweezers never worked for me.

[ellisz]

BTW, I sucked out a nudi from the mantle ridge of a maxima clam I have. I noticed eggs as well. I had never seen nudis or eggs laid any where else before ...

[juniormc8704]

Are there any reef safe predators of nudis?

[wentreefgirl]

None yet found.

various wrasses of the haliocheres sic? genus will eat them, but they likley won't be able to eradicate them

[islandcreation]

Hmmm... For me I do both a quick fresh water dip and a iodine deep for atleast 2-3 minutes with a good swish from side to side. For the egg colonies their a pain in the a$$! I found the easiest way was to lightly inject them (barely) with kalkwasser just like what you would do for aiptasia's. I even do that with nudis I find! I hate them with the passion and love it when the melt with kalk on them ha,ha,ha

[tony1970]

hmm wonder if we have nudi's cause just recently for no reason at all the zoo colony went from about 25-30 polyps down to 17 in one week. in the process of trying to get friend to get a closer look at the colony for any predators. i mean only way a zoo colony can really disappear like this is, something eating them correct? rest of tank looks good tho.

[c.rob]

How do you know a nudi laid those eggs? Did you it happen ? I have those eggs on a zoa frag now but I haven't seen any adults to speak of.

[luisgo]

Check these two articles about killing nudibranch eggs, They are excellent. They are ussing potasium permanganate to do the job.

Good lock!!

[shikhyung]

What is the Nudibranch do to the Zoos? Thanks,

[wentreefgirl]

Nudibranchs say ding ding ding, its dinnertime. Munch munch. And dont stop till the house is clear of zoo's.

[Zeezorm]

Yeah my tank i quite infested. I had colonies of 30 zoo's and they have been reduced to about 3-4 zoo's left to a rock. doing anything I can to desimate my infestation...

[jeremyj0247]

how big do the nudibranch get. If they are what I think they are, my lfs had a nudi in their reef tank along with a lot of zoa's. smart huh.

Most of the ones I've seen are between a 1/8" and a 1/4".

[wentreefgirl]

You guys need to start experimenting with the potassium permagenate. Like they are on the sps board.

[ryddo]

Are these the same nudi's that are found on sps? The reason i ask is that I have both zoos, palys and sps in my tank and I just noticed these guys in my tank this morning. The only place that i have seen them is in the section of my tank that has the zoos and palys but none on the sps. I have also found some eggs on the zoos and palys. Will they lay their eggs any where else but the actual coral?

[wentreefgirl]

Yours look different then ours. Yours are green. OUrs are off white and look like a mop head. Old yarn mop head that is. But im sure they die the same way. :lol:

[Rosseau]

Here's another pic.

http://i146.photobucket.com/albums/r265/rosseau52/palynudibig.jpg

What I am assuming are nudi eggs are visible on the left side polyp. The potential mother is also in the pic.

[rlabriola]

c.rob...i have had the same problem, it is because these nudi's are hard to see..they blend very well with the rock and zoa's. best time to see them is 15 min. after the light go out...turn the lights back on when all of the zoa's are closed and you will see the nudi's then snacking n your polyps.

[chillman]

I use a turkey baster to push water over the polyps so they close and then use a flashlight and magnifying glass to look for the eggs.

[ZOAKEEPER]

There are some good pic's posted here. They always make for a good discussion don't they. My 2 cents, I would never knowingly buy something infested even for my QT tank. No matter how pretty or cheap!!Great thread!

[bohannbj]

Good luck

[RedSonja]

I've used potassium permanganate on zoa-eating nudi's with success in killing eggs and nudi's without killing any zoas. PM me for a link to the write-ups if anyone is interested.

[TheFishGuy,LLC]

You can pick up potasium permanganate at places that cary Jungle products. It's labled for fresh water as "Clear Water". I have a friend that had been having nudi problems for a while. He started using a diluted dip of "Clear water" on his colonies and has mostly exterminated them all. I have seen 2oz bottles of this stuff at Walmart and 4 and 8 oz bottles at petco/petsmart. It's also good for a quick ORP increase. 5ml will raise the orp about 50mv in a 225gal reef in my experiance. So far in the 15 years that I've been using this stuff I have never seen lasting ill effects in any aquatic environment. Xenia shrivel up abit but come back after an hour or so.

[Legacy2005]

seems like i have managed to get some into my tank. may have hitchhiked on the new zoo rock i got. they seem to be confined to the 1 rock, managed to pick a few of them off last night with a light shining on them to see them. but im still left with a few polpys that have eggs on them.

think it would be safe to just cut the affected polpys off and leave the frag in qt to see if any others hatch?

I would do this, yes. Were the new zoas in your display tank at all, or did you just have them in QT?

-Sonja

[Legacy2005]

unfotunately they were in the main tank. which means they managed to get onto the other zoos i had in there.. only good thing is that i only had 4 frags in there since i just started stocking the tank. ive pulled all of them out and qted them so any left that i didnt get should starve with no other zoos to eat.

i didnt qt them since i had got them from a store that i had trusted to have clean items since they deal in SW fish/coral items only. but ive learned no matter where they come from to qt them..lol

if it gets to bad im only out $30 if they get eatten.

:(

[RedSonja]

From a related experiment, I observed that it takes about 90 days for these nudibranchs to starve from lack of zoanthids to eat, so you may want to keep all zoas out of your display til then. The better news is, every nudibranch egg case I observed hatched in 9 days, almost to the hour, so that after nine days you can start to watch and siphon out any that show up in the display and hopefully break the cycle a bit faster. If you FW/RO dip the frags you took out, 8-10 minutes of that kills the nudi's and then you need only watch for any eggs that hatch later. Good luck and please do let us know how it goes.

And yes, QT always, every coral, fish, LR, macroalgae, etc. I was lucky to catch the nudi's in QT and be able to deal with them there, but it was enough of a scare to convince me that QT is absolutely required, every time.

-Sonja

[Legacy2005]

trust me ive learned my lesson, the reason i didnt was that another member has been buying from them for a few years and never had a problem, 3 frags in and i get wacked.

i did the fw dip for 3 mins, the corals didnt seem to like it much which is why i pulled them out early(lots of mucus, shrivled up). one of them went from nice tall brown stalks to a shrivled clump that can bearly pass for a coral.

will the nudibranchs only stay on the zoos or will they wander around on the sand/rock? that way i know what i should be looking for. would it be wise to close the tap to the refugium side of my sump or will they not be able to live/reproduce with out any coral to feed on?

[RedSonja]

These particular nudi's only eat zoas but they will wander around the tank, and lay eggs everywhere and not just on zoa polyps. I wouldn't close off the fuge though, for the stability of your system.

Yes, FW/RO dip will make zoas mad but I've left them in FW for up to 30 minutes and they've always recovered in a day or so. YMMV and all that but until I timed how long it took the nudi's to die in FW that was my standard time for FW dip.

that is the best pic i ave seen of the little buggers and combined with there eggs great shot...the questionable one looks like it is just a small nudi...but it could also be a miniforamin (sp) you will find them on zoaid...

also for those who cant see what is eating or destroying your zoas...do a FW dip and see what happens....if nothing falls off then you may have a worm that is doing the damage...also closely inspect the colony after..as the spiders will not let go under the FW dip.. lift any loose piece of polyp mat to look under it as this is where nasty things tend to hide...

[KillerReef]

while we're sharing, here's a pic of mine being QT'd right now. Eggs have been tweezed...
