Zoa nudibranch egg removal

[fragtastic]

So, I have a couple new colonies in a quanantine tank that had some zoa eating nudibranchs on them. Dipped the colonies so the live nudibranchs are no more but there are lots of egg sacs left that are proving difficult to remove without damaging the polyps. Anyone have any tricks for getting them off?

Thanks,

Mark

You can remove the colonies from the water for a couple minutes without harming them and with a pair of tweezers you can carefully remove the egg sack all at once. They pretty much stay stuck together in the egg sack. Then place the colony ina bucket with tank water and use a high flow powerhead to blow off any that may have come loose and stayed.
If you have nudi eggs and you remove them all you still need to quarantine the colony for a couple weeks just incase some slipped by.

It's a PITA anyway you try it. I used a clamp light and magnifying glass to find them and toothpicks to remove them from the polyps. Your whole body will hurt afterwards...

That's what I'm finding. Did a bunch of this several years ago... I don't remember it being such a pain.

I bought some from a guy knowing they were covered in nudi's. I had never messed with them, so I figured I'd give it a shot (they were relatively cheap-high ends zoas). I found that havign smalle rpieces was much easier, as you could inspect easier and feel good about not having anything. Of course, that means more time spent doing it...

Pretty much what everyone else said. I used tweezers and EYE PROTECTION

Freshwater dip then iodine dip..... Then tweasers!!

I had those little buggars a few year back.my whole tank was infested. I introduced a green coris wrasse and have been nudi free ever since. I even remember about a year ago I put a fist sized rock full of zoos in my tank and noticed that it was full of nudis. that wrasse swam right over to it and picked it clean right in front of my eyes

Wow, I wonder if that was just the green coris wrasse you had, but if not, that would be awesome and solve a huge problem.

I dont know for sure, I still have him and no nudis. I had one that died before this one for years with no nudis.I got that one to kill the pyramid snails that were destroying my clams, which he did with gusto.I bought a six line wrasse prior to the green coris that did nothing but eat fish food.He was lazy.about three to six months after the 1st green coris wrasse died I noticed my many large 200polyp+ colonies of zoos thinning out and withering away.Thats when I noticed the nudis everywhere.they took on the color of whatever zoo that they were eating so they were hard to spot unless you really looked hard. After trying many diferent methods to get rid of them I reintroduced another green wrasse, the one I still have today.nudis,nudi eggs, flatworms all gone and still gne after many new coral introductions w/o quaranteen. Including one colony that I could see the nudis all over it.knock on wood

^^ wow what a great informational post ^^

anyhow, I had read that using salifert flatworm exit would kill nudis. and then waiting a little longer for any eggs to hatch and using it again would kill the new nudis before they have a chance to reproduce. anybody got any experience with this method?
(When I had spotted a few nudis, I didn't have acces to this, so I just bought a yellow coris, which seemed to do the trick )

FWIW, I use a few drops of salifert flatworm exit and lugols on a FW dip I do before introducing any new zoas to my tank.
