Zoa eating nudi?

[Living Ocean]

I was looking at my tank today and everything seemed fine. All of a sudden I noticed one colony of my zoos was all closed up. I looked and to my amazement I saw this:

Now maybe I am just lucking but I have never had to deal with these before, but is this a zoa eating nudi?

I removed this one from my tank and it's the only thing that I have seen. I saw that one my zoos looked a little "chewed" so I'm assuming this is the case. Is it possible there was just one and that will be the end of the story or should I take some other action?

Thanks

Yes that is a zoo eating nudi. Remove all that you can, as well as any egg cases. The egg cases are white in color and spiral in shape, up to about 1/4 inch in diameter. They tend to be laid on the under side of the polyps. Use a careful eye, as the nudis can be smaller than a grain of salt, but they can be spotted with a trained eye. Spend a short period of time everyday checking for nudis and hopefully you can remove them before they become a huge problem.

Just two nudis or one egg sack can lead to a serious problem.

DIP what you can dip, scrape off ANY egg sacks, get some wrasses if you don't have any. See the sticky pages about zoanthid nudi eating wrasses.

Get a yellow coris wrasse, may or may not eat em depending on your luck.

I used to have to suck them away from the zoas everytime i see them but they will keep coming back, especially when new zoas rock are added.

They seems to hide in the crevices of the new zoa rocks coming out full force at night to feed and breed.

Definitly do a round of dips on all zoas (to see what you find, might be more that are hard to see) and while dipping, look for eggsacks on the dipped zoas that have closed up.

Somtimes its hard to see the sacks when the zoas are open.

Keep a close eye on your tank for a while regardles. Have you added anything to your tank, very recently, that wasnt dipped prior to adding into the tank?

Hope the one you found is the only one in the tank....If not, these can be overcome, just a pain in the but, and not always the best for your zoas- but better than having these guys in your tank.

Major speedbump, or with luck, minor, but not the end of the road. Best of luck to you. I have been there....

My lesson learned from the whole experiance- Dip! and when in doubt, dip again or quarentine! Right from the start.

Thank you for your responses. I have not seen any since I pulled this one out albeit I haven't had much time to look. I did look tonight after the lights had been off for awhile and I didn't see anything either.

I just recently got all of my zoos as I just started with them at one time and just tossed them in my tank . I then purchased one other colony not long ago and put it in there. I assume that it came from that one.

What should I dip the zoos in? Also, does anyone have a picture of what the egg sacks look like.

Thanks for your help, and with time, I am learning...

if possible definitely get a wrasse. my yellow coris destroyed those nudis and he will save you a lot of time spent from dipping, etc... good luck!

Has pics of the eggs. I add a drop of flatworm exit to the bag my zoas come in, about a drop per quart, adding or taking away water to make that amount, for about 15-30 minutes. This will kill nudis, worms, flatworms, basically everything except the zoas, then rinse them in new tank water. Then look them over carefully for eggs before placing them into the display. Eggs have to be removed with tweezers and if done carefully the entire egg sack will come off as a whole. If you do find eggs after you remove them you will need to hold the zoas in front of a strong stream from a powerhead in a bucket of tank water to make sure that any eggs that might have not come away are removed.
