Eagle Eyes shrinking, diminishing...

All other Zoas seem fine; most of them are growing very quickly and prospering. Tubb's Blues, Fire&Ice, BamBam's, Radioactive Dragon Eyes, etc. My Eagle Eyes just seem to be suffering and they're in the prime location.

Has anyone seen anything like this? I don't see any sea-spiders on them or nudibranchs. They just seem to be shrinking and shriveling away over time. Shame, they're so pretty. Can post pics if needed. Water parameters are all in range... No other coral/fish issues.
 
give them a dip in coral revive or another cleansing dip. When I have noticed zoas diminishing i give them a few dips and most always they recover.
 
Like iodine? Is this to clear off parasites, or is it to provide nutrients?

Unfortunately the Zoas are sort of attached to the main rock, so there isn't a good way of prying them off without further damaging them.
 
OMG I'm having the EXACT same issue! My giant (200+ polyp) colony of Eagle Eyes doesn't open all the way anymore like they used too. They're attached to a main rock so I can't remove them.

Somebody told me to blast them with a turkey baster every day for a while because it might be caused by decay of the rock or lots of crap on the rock or something. I guess you could try that too if you wanted. :)
 
I had a fair size colony from the beginning survived 2 crashes and a move over the course of roughly 2 years. One day they started to go down hill, did iodine dips and water changes. Nothing helped just wasted away to nothing. It sucked and good luck with yours
 
I had the same issue with a colony of eagle eyes, I cant say the results were good, but the turkey baster is as good an option of any. I hate when something like this happens and your params are all good and you just have to sit and watch a coral melt. It is so discouraging.
 
Unless you can move the rock out of the tank to treat the zoos you're probably going to lose them. Sounds like white fungus, or zoa pox and the only think I know that will cure those is dipping in Furan2 solution. (See under sticky threads).

Sorry for the bad forecast, but it's happened to me where I couldn't feasibly get a rock out and lost a 200+ polyp colony.

Thanks for the info Fcamdog... I am now totally paranoid that I have something like Zoapox. I lost a couple polyps of my hypnotic cloves (but the rest are doing quite well and have full color and extension). From what I understand, a fungus would be plainly visible as a thready growth, and that's not what I am seeing.

A nearby colony of Tubb's Blues have not been opening recently and some Fire & Ice to the left have been shaped oddly (center bulging) intermittently, or not fully open.

If it's Zoa Pox I'll have to pry off the Eagle Eyes colony and treat it with Furan, but I'm curious about what to do if it's spread to other colonies (likely) and whether my whole tank is now not viable for Zoas anymore if it's host to Zoa Pox (like an Ich infection). I'll try to get some pictures tomorrow.
 
Here is the colony in question (in the middle). This was a week or so ago, no improvement. You can also see the Tubbs that are looking unhappy below the Eagle Eyes. This colony used to be quite happy, open, and colorful.

Never dose anything without being able to test first! If you don't have an iodine test kit, don't dose iodine - in higher concentrations iodine is toxic and can crash your entire system. If you think there is an issue with a particular trace element, the best solution by far is to do partial water changes. If you do water changes and there is no sign of improvement, then your issue is most likely not water chemistry, but some sort of pest. In that case, dips (iodine or otherwise) may be in order. Keep in mind that some zoa colonies in nature go through natural seasonal fluctations in growth of boom and bust, and that this behavior may carry over into our tanks, and therefore could help to explain why some colonies simiply close up and die off with no known causes (topic was covered recently in Coral Magazine).
 
Thanks. I do infrequently dose with 2-part but mostly just do a 5 gallon change once a week or once every week and a half, which is fairly decent for a 29 gallon tank.

Doesn't look like I have zoa pox. I'll just have to wait and watch them die, I guess.

Just read that article the other night. Volume 7 number 3, May/june 2010. If you can get your hands on this issue read it. Lots of great info for zoa collectors. If your zoas are the carribean type (Z. sociatus) there might be nothing you can do to save them as Scopas stated. Good luck
 
I have the similar problem ...center bulging on some of the zoas and some of them are slowly reduced in size and melt away.

I was having some similar issues with some nightmares when I had fallen behind on my weekly water changes. Did a larger than normal water change and multiple smaller ones after that, and they are recovering nicely. Can't tell you for sure what element was causing my issue, but it was obviously related to water chemistry.
 
holy cow, I posted something like this recently as well, just came across this forum. I've lost a whole colony of some pink zoas and some other colonies as well. Started with a swollen polyp and then the whole colony melted away. It's affecting certain colonies but not others. Driving me insane!

Did you try aggressive PWCs as suggested by some other people? Any results?
