Advice from the zoo gods please...

I have a few zoo frags in my nano and would really like to get some more and have them actually grow and look cool. It seems that some of you have incredible luck with zoos. Needless to say, we've had craptastic luck thus far keeping zoos and getting them to grow. So far, I'm having hit and miss luck with the ones in the nano.

What's the magical secret? I know my sexy shrimp don't help the situation as they prance around on the polyps all day long making them angry. But other than the zoos, all the other corals are doing very well. Any ideas, special tricks up your sleeves, thoughts? Thanks a bunch...
 
im not a zoo god like Fan...but i basically toss mine in the tank....and they grow.....

sorry that doesnt really help..LOL...they only slow growing ones i have...are some red skirt, darkblue zoos

**i dont dose anything for my tanks** and everything seems happy
 
Rev is the zoa god. I'm like Gsusfreak.....they just seem to grow.....and would do much more if I'd keep my hands out of the tank. The zoas/rocks that I can't get to and move, are flourishing big time. Every time you move them, they will take time to adjust to the move.

My first several tries at zoas failed miserably. I invested way too much in zoas with an 'unstable tank.'...even though I the params were good, there was something not ready. My tank was probably just not mature enough to handle them.....and I'm not sure how you can measure that.


Off topic....
Here's a pic that I just took of my goby. He sits and watches me all day long, and I can get a reaction out of him when I put his photo up on my screen. He can definitely see the image on the screen!

Well I am no Zoa God (lol) but maybe I can help you a bit.

What type of problems are you having? We have to eliminate some things first.

How dirty is your water? Clean water=slow growing zoa's.

i would say that is wrong i have a skimmer 4 times oversized and run ozone


i would look at your light and flow
 
Okay, here's the story on my 24 nano setup:

Skimming - nope. It's a regular old JBJ nano, so I've got the basic set up, no bells or whistles.

Lights - I was running the stock PC lighting that comes with the JBJ hood. I did buy one of the Viper lights from the Critter on Saturday and have that on the tank now. I run the lights about 8 hours (noon-8PM) per day.

Flow - I have an MJ900 in the return and a Koralia 1 in the tank. We put the Koralia in about the same time we reworked and opened up the rock work. The corals overall look better since we've done this.

Temperature - Before, with the stock PCs, the tank was running about 80ish. We're jockeying with the temp now that the hood is off and the tank is open with the Viper. Right this moment, it's running about 77. In the process of getting everything adjusted with the new light.

Bioload - I have ~4 sexy shrimp, a green clown goby, a white ray fin goby/tiger pistol pair, misc. hermits/snails, and a scutus.

Feeding - I feed the tank every/every other day with a pinch of flakes. Periodically we feed some frozen Marine Cuisine and some cyclopeeze.

Water - We use Instant Ocean salt, and do a water change about once every week (or two if we get behind schedule)... We don't dose the tank with anything.

We have had really bad luck across all the tanks when it comes to keeping zoos. We had some giant pink zoos we got at the 2006 swap that grew like weeds, but that has been it. We just can't seem to really keep them. They certainty don't grow to say the least.

I have a few small frags that we've accumulated over the last year or so in the nano, and they have either been staying about the same or slowly disappearing. I have 3 frags (from the Critter's frag tank & EBay) that probably have about 100 or so polyps on them each that seem to be doing fine - I've had them probably about 3 months or so. I've recently mounted them onto larger rocks in hopes of being able to track any growth if it does by chance happen. The zoos are spread out around the tank as far as placement. I've got some at the very top of the tank, some in the middle, and a bunch on the sand bed.

I have a good mix of corals in the tank that are growing and look healthy (mushrooms, hammer, duncans, leathers, candy coral, rics) so I can only assume (I know, I know) that the tank can't be a total disaster zone of death.

I had mentioned before that I don't think the sexy shrimp are necessarily doing the zoos a favor by prancing around on them day in and day out. I've asked around and done some digging but haven't found anything that's said there's a link between sexy shrimp aggravation and zoo issues. There is a trade off with the zoos on the sandbed. They seem to be doing the best there so I've let them be. However, the pistol periodically decides to renovate the sandbed and has been known to toss some sand onto them. I dust them off and just let them go about their business.

We make sure to dip all of the zoos for bad guys before they go into the tank. Depending on what we have on hand at the moment, we either use Lugol's or TropicMarin Pro Coral Cure to rid the zoos of any unwelcome hitchhikers. I've not seen any nudis or other said critters in the tank before.

I know I probably missed something, so let me know :)
 
FYI.....I have 2 sexy shrimp in my 12g with zoas, and 'had' them in my 5g zoa tank. I've yet to notice any problems with them.

Also.....is it possible that you're not noticing the growth? I look through old photos to find out exactly how much growth I'm getting. I typically don't notice it until then.
 
zoos seem to take forever to grow, then they sort of "snowball". my 58 is a mostly zoo tank and all the colonies are thriving, but i chalk that up to me running a skimmerless set up
 
Fanof49ASU - There are a couple of small frags that have added a polyp or two over the course of probably 9 mos. to a year. They seem to periodically close up and some die off, then they recover for a bit. I would say that there has been a net loss on every colony of zoas we've had for longer than 6 mos. (other than the pink zoas Moriah mentioned and a set of radioactive dragon eyes that have possibly doubled in the 1.5 years we've had them). We aren't missing any growth for sure... most of them are clearly dwindling over time.

I've heard that they frequently snowball after a few months but we've still yet to witness it. We haven't touched any of the zoa colonies on the rock work since we redid it (sometime before the Ebay meeting).

We're frustrated... everyone told us when we got in to the hobby that zoas are easy :-)
 
When I got started with zoas, at first a few melted away and a few got killed off by GSP, that's why I'll never have them again, although I do see some coming back slowly......They are hard to kill off I tell ya....Some of the zoas I though I've lost have came back, my very first colony is grown sooooooooo huge since I never frag it for the past 3 years, it's becoming the home of my clowns.....One thing I've noticed is once you get them home, you need to place'em in high flow, it helps a bit, then you can move them where ever you want after establishment. I've gotten some zoas at last year's frag swap just starting to take off now, it took forever, but I guess my tank is ready for them now and all the zoas are taking off like mad.....We'll see how the new ones do in there, if they all take off, something good is happening... :)

By the way, if it's a newly fragged zoa, place it in Actinic lighting only until the next day. It encourage it to open.....

a little dirty water(nutrients) high light and high flow make zoa's happy.
actually i find them liking medium flow....lighting depends...you can tell when you need to change bulbs when zoas expand in size...either way they produce like mad for me...
 
Do they live and just not grow, or do they slowly die off? If they are dying off, I'd tend to think you might have some sort of pest runnign around. I've seen nudis crawling on tanks at LFS's (monti and zoa), so I know they have them. Dipping is a good start, but if there are eggs hiding out anywhere, you are introducing nudis. Frags are usually easy to pick through for nasties, but larger colonies have too many nooks and crannies to be sure to get them all. It's looking like they may have a killer for the eggs now in a dip (Potassium permanganate). I know it was tried on monti nudis, but not sure how much its been experimented with on zoas.

Somethign else to look for with larger pieces is die off from within. I've had several that came in on those acro skeletons that start to crap out. When I crack the skeletons open, it is filled with the black sponge. I've also gotten three frags/mini colonies from EBay on the same substrate (a homemade Fungia skeleton made by the suppliers of the corals to EBay) that slowly killed all of the Chameleon People Eaters that came on them. All three of them did it. I had to cut them off the rock to get them to live... Still haven't figured that one out yet, either.

If they are living fine, but not growing, that gets tricky. Some I've had take 3 months to start doing anything, then they take off. Others have taken off from the beginning. Most of mine grow well for me (aside from the Armageddons and Red Wines that melted away-still holding onto 2 polyps of Armageddons...), but my PPE's had 3 polyps when I got them about 6 months ago, and they still have three polyps. I have them pretty high up in the 120, so I'm wondering if that might do it. I've never been able to get mine larger than ~1/4" diameter, either. I know others keep them in higher light and have good growth, but I haven't figured that one out yet. It doesn't make sense when other things are doing well and still no growth... It can certainly be frustrating. I know lighting has a huge effect on the size of the polyps. When Casey had the bowfront, he was running the Odyssea fixture (175W DE's and PC's). It didn't put out much light at all, so all of his zoas and Acans (Indo back then) were massive stretching for the light.

As far as nutrients go, I'm running an MR4 on a 125 and an MR2 on the 120 and pulling 5-7 gallons of nasty crap every week, so I'd say my tanks are relatively low nutrient. Anyway, enough of my jibberish...
 
To answer your question Gary, a little bit of both. The larger colonies I have are holding strong with no growth. However, just for example, I bought a frag last year at the swap that had probably 12 polyps on it at the time. As of last weekend, it was still at 12 polyps. Over the last week, the frag has melted and there are two polyps left. They were not fancy shmancy zoos, so it is not a tragic loss, but you can understand my frustration. Fine (without growth) for almost a year to the day, then death. ARG!

I think I am going to try to start taking pictures on a schedule to attempt to document any growth/death that is occurring with the frags. I don't know that this will help with anything, but it's worth a try. If I have critters that I don't know about, somebody's eagle eye will inevitably spot them if I post some pics. If some of you crazy hawk-eyed folk can find red bugs in pictures, you can probably spot some other devil bugs if they are there.

The tank will get a scraping tonight and we'll see what I can get as far as shots. Maybe something will be very obvious that I'm missing. Who knows...
 
I'm horrible about feeding... The acans would be happier, too.

Sounds like a good idea, Moriah. You could have a Moriah Zoa thread and track it all:).
 
Also be sure to dip or Qt. them if they are wild caught to get rid of pests before you throw them in the display nudis and sundials can sure keep them from growing or living at all.
 
Ive noticed recently, that dipping isnt doing the trick. Im doing 10 drops lugols to 1g of water plus flatworm exit for 15-20mins and still find all kinds of critters after words. I know dipping does not kill eggs, and Im not finding babies.
