Concerned about my Zoas

[jocoxVT]

Here is the story picked these guys up a week and a half ago and this is what they started out as...also would like to note that before putting them in the tank and inspecting them I found a sundial snail which was removed but nothing else was found at least by my eye.

Now they look like this:

The only thing that changed since getting them was that they were shifted because they were leaning against the rock and I didnt want them battling my other zoas on that rock. It almost seems like half the zoas are open the other half are "balled up" for a lack of a better term:

The zoas came from a VHO lit tank and looked fine. I have them in my sand in a 100 cube (30 by 30 by 25) close to a rock. Does anyone have any thoughts on the matter? A dip is in store for tomorrow but any other thoughts/opinions would be greatly appreciated.

i told jocox that something doesnt look right.

those polyps are obviously dying, as you can see dead tissue and whats left from some polyps.

he needs to do a zoa dip, and get rid of all the dead/decaying tissue. and frag off a couple of healthy polyps and put them somewhere else in the tank.

anyone else got any ideas what is happening? he says he hasnt witnessed anything eat them (crabs, nudi's, etc etc). doesnt look like any fungus growing on them.

also, i didnt mention this before, but you may just want to wake up in the middle of the night and look into the tank to make sure something isnt coming out only at nigh to eat them.

i'm sure all of his tank parameters are fine, as he has other zoas and corals that are doing fine.

EDIT: oh yeah, he's got plenty of flow in that tank (powered by those new vortechs, and he's running 2x250 12k reeflux MH's.

Oh boy, those are gorgeous and saving these are gonna be tough. What does the rock smell like? Is there any obvious sponge growth on the rock? I know sometimes the death and/or decay of sponges on rocks that went unnoticed can cause the demise of zoas living on the same rock. Also, is there anything that might be picking at them? What are your parameters like in your tank? What lighting and flow conditions are these guys in at the moment? I can tell you that some of these PE types are ultra sensitive to light and/or flow in my own experience. I really hope you can figure this out because that is one of the nicest morphs I've ever seen.

All paramaters are fine in my tank at least what I normally keep everything at:
Salinity - 1.025
Alk - 11.5
Calcium - 420
Temp - always right inbetween 79.0 and 79.5
pH - 8.28
All Trates and Trites, Ammonia, Phosphate - Undectable

All other SPS/Zoos show no sign of distress this is the only thing struggling right now

The frag is actually on what looks to be a birds nest skeleton and to me they smell fine and I dont see any possible sponge growth that may have been impedding on them.

Right now they are in a 100 gallon cube (30 by 30 by 25) under 2 250 watt Reeflux 12ks with 2 VorTechs on a wavemaker. I already have fragged off what looked like 5 healthy polyps and moved them away but obviously if possible the more I can save the better.

JocoxVT--
I would definetly dip them. be prepared to frag off the good polyps and consider the others a loss..
sorry about the bad news.. Talk to you at the zoo....

 

[jocoxVT]

Thank Matt, I already did frag off a good chunk of polyps that were all opened up and moved them to a frag plug...hopefully the dip will help save the others!

If it was me, I would frag off any other healthy polyps and just do the dip on the sick ones.... those are georgeous looking zoas to be losing.. I'm sorry about that.. but I know the survivors will get back to their glory days..

keep us posted...

Thats actually not a bad idea at all. I will look in to doing that when I get home I plan on dipping even the good ones when I get home anyway just to be safe.

 

[thrlride]

We'll dip them in lugols as soon as we can get together, I've got some...

IM sorry to hear your lossing some of those great zoas and well not an expert on zoa cases but i had a colony that was in branch or piece of rock with branches like yours and after awhile i ask and that piece was wild caught .. short story it didnt do well in my tank while other zoas were wonderful so i did what mentioned here i frag the good ones dip the good and bad zoas then months later of having like 30-35 polyps know i only have 5 survivers ... i think that wild zoas tend to dont do well at tank life... so good luck with them .... and hopefully you'll save alot cause that colony you have is amazing....

Dipped the zoas last night the original frag from two nights ago looks great right now the ones that were suffering before are still suffering. I will try to get some photos tonight to post up
