Good or bad??!! ID Plz

[dherrera83]

Found two of these guys and i am not sure where they came from but they were spotted once the lights turned on. Never seen them before so i assume they only come out at night.

Here are some shots...

1st pic is of the smaller one i found by a poly.

2nd pic is of the larger one i found by a small zoa colony.

Thanks!

Not good, you need to remove them as quick as possible. They're Zoa Nudi.

Zoa spiders!!!!! very bad! Get them the hell outta the tank!

 

[dherrera83]

I chopped the bigger one up with a surgical scalpel, do you think that did the job? Or do you think i would need to arm myself with something more effective.

UGGGGG. I would inspect every colony you have for more of them. Also they will lay their eggs on the sides of the polyps. you will need to actually scrape them off.

 

[dherrera83]

I picked up the body with a small cup and flushed it, dont think i left anything behind. The smaller ones might be a little more difficult.

Any eradicating suggestions??

Yep those are Zoa eating Nudi's, dip your zoas asap, and look for the eggs attached at the neck of the zoas, they look like swirls white, each swirl has about 40 eggs, once they hatch ur screwed. Use Revive to dip the colonies. FYI the eggs won't die in the dip they need to be removed with a tweezer. Goodluck

Ok, soon as the baby goes to bed i will get in and remove them and scrap anything that doesnt look like a polyp.

You will be able to tell if they are eggs.... I dipped mine in Lugols when i found one.

The Nudi will turn the color of the zoa that it just ate as camouflage.

WHAT!! Dude you are so right! The first one is redish orange and the zoas next to the ones its on is redish orange! The second one is greenish and the colony its on is GREEN!!

Cant wait for this kid to go to bed!

Got a link to the dip?? I am sure i cant get it now but i am going order it..

Thanks everyone for all the help!!

I would not wait. Lugols is iodine. If those things hatch you will not have any zoas left.... just Google lugols. I picked mine up at lfs

 

[dherrera83]

I have iodine, could it be a different one?

I am not sure.. Google lugols. Maybe someone else will chime in

You could also just dip them in fresh water, make sure the Ph is adjusted, and swirl them around, they should come off. Also take a turkey baster and blow the water on the zoas, that should also help remove them. As was posted, the eggs are very easy to spot, they're usually a circle/sprial type pattern, and you can pull them off very easily.

 

[dherrera83]

Thank u guys so much!! I will update after my attempt.

I would check the tank often though since you want to make sure that you get any that may not be on a colony. When I found one in my Nano it was crawling across a rock. I thought I was seeing things I thought it was a zoa that was moving. Another reason that all frags should be dipped and inspected. Just a dip alone may not kill the eggs and if you don't look for them then you may wind up with an infestation.

There are many cases of these here and on other sites. I had monti eating nudi's and the only way I was able to get rid of them was to leave the tank bare of monti's for a year. The eggs will fall off, some of them at least but people have tried many things to rid themselves of these only to find them in a few months after noticing theis corals closing and dieing. Studies show that a concentrate of garlic and saltwater and manual scrubbing is your best bet. I think the average was 4:1 Garlic juice/extract to water. Wrasses in the coris family may help you as well as some may eat these nudibranches. Everything is hit or miss. Good luck, they are not easy to get rid of and certainly impossible to rid yourself of in one night.

These 2 links may help. Although they eat different types of corals the erradication of the nudi is exactly the same.

A few more for you to read.

Many opinions out there, I will post more as I get to them from my bookmarks that I have saved.

Again good luck and I hope any info helps you out.

Also as a final note, DR Mac says it in the link All the treatments were tried on the actual nudi. They may work. The eggs are your issue. Very few treatments have been found to have any impact on the eggs. Once they hatch, you have the same issue all over again. They also mature and lay eggs extremely quickly. Without pulling the colonies and QTing them it may be like running full steam head first into a wall with no helmet on.

my attempt

So i removed all my frags and the small colonies and dipped them in freshwater. When i blasted them with the turkey baster they all fell off, all 4 of them. Not sure if that was all of them but i will continue to look for them every chance i have.

I did notice that they had laid eggs but was only able to find one of them. I will continue to check for them on the rocks, frags and polyps.

Wish me luck and heres the pic of my find.

Thanks,
D

whats up D, I had these a while back, I would dip all zoa frags/ colonies. Get aggressive with these guys, they take over quick. I heard some wrasses eat them but that might not be an option for you.

 

[dherrera83]

Thats man, doing good. Looks like i most of them out. I did dip everything in freshwater and seen them come right off. Dont have anything else to remove them with. I also removed the eggs i seen. Hope that does the trick.

Dipping everything from now on.

I look for them every morning, when i get home form work and before bed.
