When I donated these to friends and the pet store, it didn't solve my problem.

What happened to the frag you donated? Same thing, different?

schristi69 made a great suggestion. That would be interesting to see what you found.

Also, what kind of animals (fish in particular) do you have?

If there is a rogue animal eating most of the colony, it's possible whatever they leave behind is eaten by worms; which is normal.

I had a similar problem with zoas once. It was because my Salinity was 1.041. Dumb mistake, fixed it and my colonies grew back.

I'd be interested in hearing about how long people have been able to keep a colony of zoas going. I don't consider 1 ,2 or even 3 years a success. How many times have we read on these posts about zoas disappearing. I'm not suggesting that nobody can keep them for forever. I'm sure there are plenty of sucesses out there. But I don't think anybody has a clue as to what is going on in our tanks in regards to this. Those that are sucessfull (5 yrs or more) with a particular colony of zoas have a commen thread. We all need to figure out what it is.

I have a friend that has a colony of zoas that is about 7 years old. It's very strange to see how they've developed.

It's almost as if they creeped across the tank. Yet, it's not like they grew exponentially and overtook the tank. As they grew out, the polyps at the back of the colony died out. Almost like the mat would only contain a set amount of polyps and any extras died. So the mat just creeped around the tank killing what they could and growing around the rest. I have some of the colony in my tank now.

It's kind of cool.
 
Just an update. These were as good as gone. While they were on their way back they were looking like the average dull rpe's that you see everywhere. They are looking more and more like the bright red that they used to be. Hopes are high that they will make a full comeback. I'm glad I tried that dip because I think it worked and these have always been my favorite zoas. Maybe they will finally begin to multiply. FWIW.

My zoo's have been closed now for a couple of months. I don't see any sign of deteriorating but I am going to do a fresh water dip on all of them. I read the post on this and was wondering what the best way to raise the PH of the RO water was....

Thanks
 
I have a question.....I have a pretty large colony of green zoos....last night I was looking at the tank and I noticed in the middle of the colony there was this string of brown looking mucousy stuff that resembles caramel trailing out of the middle of one of my zoos that had closed up......anybody ever seen this or have any idea what is up with that...????

Update on Zoo's

I did a fresh water dip about 2 weeks ago and the Zoo's looked about the same , alittle tiny bit opened at the tops. Well i did a 25% NSW change twice in one week .. My Zoo's have all opened up even the one's that weren't dipped. After being closed up tight for nearly 2 months they look fine. I don't know quite what this means but I thought I'd share it and see if anyone has any ideas about what has transpired.
 
Is A fresh water dip the best treatment for parisites, or should I use an additive like Kent's Coral Dip?
 
I was also wondering about the Kents coral dip. I didnt try it because it says not for colony type corals and zoos are usually in colony form. Has anyone tried it? It really is an iodine based dip but you mix it in your own salt water instead of the fresh water dip.

apparently its not just me

apparently its not just me

I ordered about 10 different frags from some guy in California about 1 year ago and I would say 4-5 months after going into the tank I was amazed at just how good some of them were doing, I had a few colonies that started at maybe 3-4 polyps and had grown to 30-40, even 50+ polyps. about 2 months ago one colony of red zoos just out of the blue started "melting" away on me. i pulled the whole colony and threw it out hoping this would not be the case w/any of my other precious colonies. Unfortunately a month later I noticed a white almost fuzzy looking fungus growing on the stalks of an awesome orange/green colony I have. They as well as 3 other colonies seem to be succumbing to this disease. Not sure what to do, I never really took as much care as it seems some of you do in blowing them off etc. but my water params seem good and everything else is healthy. I will cry like a schoolgirl if I lose another colony as I have a enjoyed so much watching them grow into such good looking corals. They all grow together and not sure how I would be able to FW dip them. should I tear off what I can, dip them and start over???
 
Hey guys i got my first zoa colony, a 30 polyp colony of tiny round Brown skirts, green middles, and dark purple centers. Reading this makes me scared i have them in a 10gl tank with high current and decent lighting. Within an hour of getting them they were coming out, seem to be doing good. Is there anything i can do to help prevent melting or other diseases, i never knew about dipping zoo's. kinda new to them.

Zoo's

Zoo's

I have had an ongoing battle with my Zoo's closing and staying closed for long periods.I have come to my own conclusion ,from what I have done, that water quality is a very important factor in their case. Like I stated in a previous post , doing two 25% water changes with NSW was the only thing that made a difference .. I think I was lacking something in my water that the NSW made up for and hence all my Zoo's were open and looked great in about an hour. And this was after being closed for nearly 2 months like I said. This leads me to believe in my particular case it was my water. Even tho everything else in the tank was doing fine except my Zoo's.
 
contagious infections?

contagious infections?

Been reading this post now pretty much the whole way threw. I would in interested to know if the majority of the "problem" colonies appeared to be contagious or not? Did the people who lost multiple colonies lose the one downstream from the original dieout, or was it on the other side of the tank? Anyone notice an effect if they are running UV? Anyone use any formilin or other formeldahyde based med in their dip?
 
OHMMMMMMMMMMMMMMMM

OHMMMMMMMMMMMMMMMM

I have spent the last 1.5 hours going through this very interseting thread that Mucho has started. It hss been very informative as to what to look for and possibly treat, an asset to those of us that are just starting out dabbling with zoo's.

I am new to RC as of today, but have had salt for the last 10+ years. I am starting a new tank after a catostrophic loss over a year ago do to equipment failure, and have chosen the husbandry of zoo's.

For my new project I have a 46gal bow with about 65lbs of tonga branch, 2" bed of Flordia's finest sand with approx 1" of Carib agro. To this for filtration I added a 18" CPR refugium with a maxi-jet 1200 for flow, and 18watts of 10k lighting 24/7. Lighting for the tank equates to a dual 96watt PC with 10K and 03 actinic on for approx 11 hours a day. A pair of Maxi-jet 1200's provide flow thoughtout the tank easily with the openess of the Tonga rock. This set up has been empty for approx 1 year with only the addition of 2 Saddle back clowns, macros to the refugium, small serpent stars, and pods approx 6 months ago. All rock was uncurred straight from the box approx 48 hours out of the ocean.

I provide regular feedings every 2 days for fish and critters of mystsis and cyclopeeze.

With addition of 2 - zoo colonies, 1 pulsing xenia, 2 ric's, and a sarcophyton frag 2.5 months ago. I started adding Reef buffer and Reef builder as prescribed 2 times a week along with Lugols.

All is well ohmmmmmmmmmmmmm

My point is this.

I have taken a painful amount of time and worked very slowly to develope a window to my ocean. Making small changes over long periods of time to allow the tank to reach its own Homeostasis, not to my manipulation. These animals have been around for millions of years and have flourish over oceans until mans hand changed its Homeostasis. If my tank perameters are dead on then I dont mess with the inhabitants, I let them run their course. I have had small colonies of zoo's that have had the same symptoms that I read today. In the past I have paniced and dip and added chemicals, changed this and that, and watched polyp after polyp die. I am now more apt to watch and evaluate than to act, and my success has increased. Not only with this so far, but with other tanks I have had in the past.

If I am aquascaping and I brush that rock too close and cut myself my body begins to flush the wound by bleeding. The area becomes red and mildly inflamed allowing more blood flow. As more blood flow moves to the wound white blood cells and platelets move in leaking out of the wound forming an ugly crust to stop the bleeding and form a bacterial barrier over the injured site to fight off any potential infection. Over the next few days to weeks. The wound goes from bad, very painful leaking a yellow/white clear fluid (white blood cells), to the edges growing together to a state of healing ,or equalibrim, or Homeostasis.

Could this be the same type of white growth that you see on your corals from time to time. Can this small animal have an immune system that can fight off foreign bodies by its self without out our manipulation? Could this be the answer the Mucho's LSF phenomenon?

Maybe or maybe not. I too am a man that knows everything about nothing. I know their are 100"s of ways to reef and obtain the same results. I know what has worked for me in the past, present and, with the luck of the reef gods, the future.

Thank you to all for a site to visit, read, learn, succeed, and fail, and to share these experiences with others.

For whats its worth.....

You might have one of these. this guy i saw with my own eyes eating my Zoas and taking bites out of my rics

It seems to me that there are a few things going on here.

Firstly, when more than one colony in more than one location shrinks up at the same time I think a large volume water change is called for, If you are not an idiot about it waterchanges rarely cause any problems, and they will remove chemical agents (ones that perhaps will affect some morphs more than others) and will restore any missing trace elements. However, if its one colony after another that seems to shrivle up it may be the cause of another preditor, I have a friend who had GSP's and Zoas that were doing well, then the GSP's shrivled to nothing, then the zoa colonies one by one, Later I spotted an astrinia star on hsi glass, we removed it and the Zoas recovered, then he got more GSP's and more Zoas including some flourescent oranges and they were all doing great, well over the summer his fields of big bright GSP's wasted away to nothing and then his Zoas started to disapear. Lo and behold another astrinia star showed up, we haven't caught him yet, but hopefully we will soon.
