Anyway, they've been basically closed up like this for 3 days in a row. In the image, in the southwestern corner, there are about 3 polyps that are hanging off the rock... Can anyone see anything visibly wrong? Disease, etc?

I would pick up a pack of bifuran tablets/powder from your LFS, and mix one tablet/one spoonful with one cup of tank water and dip for 5 minutes, using a turkey baster to blast it into all the nooks and crannies and to knock off any loose/dead tissue. Then pull it out of there and rinse it with RO just enough to get all the color off (my furan powder is fluorescent yellow, I think most are pretty bright) and put it back into the tank.

Then the next day I check on it and either repeat the bifuran if its a little better, do a dip of 2 drops lugol's iodine in one cup of tank water for 5 minutes if its significantly better, or if it looks worse I start aggressively removing the bad stuff with a razor and make frags of the good parts to move to a high flow area of the tank/different tank to try to save at least something to rebuild the colony from.

whooooa...slow down killer....

whats up with the tank? give water and tank specs please

how long has this been goin on? 3 days? how did they look when you got em? my zoas will close some times for no reason...some times they close up if something is buggin them

NO3: 0




It's been going on for 3 days now. I got them about 3 months ago. They looked perfect. Opened the same day I put them in.

i would try an iodine dip... has saved tons of zoas for me

+1 to above, also do a waterchange. there may be something in the water that does not show up on tests and it can never hurt!

I did a 15% water change earlier this week.

Sounds like it's time for an iodine or, preferably, furan 2 dip. If you dip furan, be sure you do it on each of three consecutive days.

definitely do the iodine dip - the flesh doesn't look too good. Then after you've dipped, leave only just the actinics on for a day or so just so you don't stress them out anymore.

Do it sooner than later or you will probably lose all of them.

Your ph could be a factor too. a little low.

Over the past week or so, I've done two freshwater dips and two iodine dips. I took out the colony earlier tonight and started removing the dead tissue. There was alot of loss, about 90%. I'm still not clear on what caused this problem though. I'm not sure if it's a pest. My other zoas look fine *crosses fingers* but some polyps look closed up more than usual (though with the problem zoas, they were 90% closed).

Don't really know to help, but my zoas all stay open all the time when lights or moonlights are on except if they catch some food or something crawls over them. I would say if some are staying closed there is something going on. That picture, about in the center, that is rot? Looks almost like a nudi.
Just saw some at the local reef shop in the display tank yesterday. Not a pretty sight. I looked because a lot of the zoas were closed up and saw a really big one, called attention to the worker there.
Frightful!
Good luck with your zoas.

Woops! I take some of that back what I said.
I had been running the NeoZeo and found that some of my zoas were not opening up all the way. Did some testing and reading and decided to pull the reactor/NeoZeo for the time being, doa water change and add a little extra dose of coral food.
They have all stayed fully open since.
But that would not apply to your tank I am sure if your water quality is within range for them.
I think my water was getting to be a little too stripped for zoanthids though the sps and acans were doing well. I need to find that balance now.

It's too bad you decided not to try a furan 2 dip. Glad you have been able to save some, however.

I couldn't find it anywhere locally. Had a hard time finding the iodine too (my next stop was the drug store for non aquatic iodine but found it at the last minute).

I couldn't find my furan 2 anywhere locally either. I ordered it off a seller on ebay and I credit it with saving 4 of my zoa frags from pox.

don't worry bout it man... there's not much you can really do.. had this happen twice this year.. just frag what you can. In the second case it was only the mother colony of the eagle eyes.. the 2 smaller frags I made from it a month before were fine (in the same tank). Did the iodine dips.. even h2o2.. only saved a couple polyps off the colony.

Ok... now I'm really worried. I had another colony that is now starting to die off. To me, there's nothing visibly wrong. The ONLY pattern I'm seeing is the zoa stalks are getting very, very skinny. THe heads look like they're inverted. Instead of being a sort of cup, they're reversed.

Another pic:


I can't really dip these as they're attached to a huge rock.

I was on zoaid.com looking at various pests... I don't really see anything wrong.

I can't for the life of me find the thread but people have had great success with vitamin c dosing.

I did have this bookmarked it explains vitamin C dosing a little.

I would dip what I could. Some zoas just melt for no reasons. Are some of these deepwater zoas? Deepwater zoas i have had vanish on me over night to a melted mess.I would try to frag some of them off the rocks and dip them.Save what you can. Zoas are like this sometimes.If all your levels are correct and you see no pests just dip and hope for the best.



I dose Vitamin C. But have read where if you start dosing vitamin C you need to keep doing it because once you quit things start looking bad. I have Tons of zoas I dose a 2 part,vitamin c and Idodine but I also test for everything.If you don't test for Iodine don't dose.

Sounds like a song

Thanks for the advice guys.
