 Topic: Zoas not Opening
Posted: March 17 2015 at 10:27am |
I have about 6 different kinds of Zoas in my
45 gallon shallow. I have two small colonies (12-16 heads) that extend but only
a few open all the way. Most just extend and they extend further than they did
when purchased (by double) and they have grown in numbers from 8 in the
last 45 days.
Why are they not opening?
I have moved them in and out of flow, changed
the amount of light they get, blasted them with turkey baster, and even rubbed
them. I don't understand how they are multiplying but not opening if they are
not happy.
What else can I try?
Will try and get some pictures up, but I am
working on getting the 210 wet.

I don't know why they are not opening, but food might help. Have you tempted them to open with something like Reef Roids/Reef Chili? Opens mine every time.

Have you looked at them really close at night with a flash light? Making sure they don't have any zoa eating nudibranchs as they will irritate them and cause them not to open.

I have dusted them with reef roids with the turkey baster. I also feed the tank weekly with BSD and new wave products.

I have only ever had four things cause a situation like this when my parameters were in check. 1 ) Zoa Pox2 ) Zoa Eating Nudibranch 3 ) salinity swings 4 ) acclimation
Furan-II can be successfully used to get rid of zoa pox. If you look carefully at your zoanthids and see white pimples all over the polyps and stalks, it is likely zoa pox. Some paly's have naturaly white speckling don't panic if you see that, if you see physical bumps it is the POXXXX
Zoa eating nudi's are a different beast all together. You're in for a fun ride if you find them. A wrasse never hurts if you can get it to eat them.
Do you have an auto top-off? If you don't, I suggest getting one. Some zoanthids are extremely sensitive to even the smallest salinity swings
Zoanthids, especially new ones, sometimes take 1-3 months to adapt to new lighting. I've had zoanthids not open up for a month, then once they adjusted were healthy and happy from that moment going forward. It is also a possibility that they are still acclimating to your conditions.

I have lowered the intensity of the lights for them. Too the point that the other corals stopped opening fully. I have moved them so they would get different light.

I've blasted zoanthids with some pretty beefy lights, they don't seem to mind high intensity lighting.

I also find that true, I had turned my whites up to high and smoked a birds nest frag and all the zoas Loved it. I think (or) hope the birds nest is coming back. The Radion Pro just has more white power than can be used in this shallow of a tank even with the 120 degree lenses. It must be a pest I have not seen.

Here I go again. Saying stuff I don't know about...
I have noticed that some of my zoas do well in places that they are not recommend in. For instance, I have zoas that are red/blue/gold in higher areas than I have my green zoas. I have noticed that the aforementioned colors each do better in certain areas. That goes against what people say is common. I also have a leather that is sitting next to an SPS. It only ever gets extension up there, but when I bring it down lower, it acts dead. Even after letting it adjust for days.
I used to put green zoas up with the red/blue/gold, but they did not perform as well. Long story short; it might be placement. Some zoas might do well where they are and others not. Thats the awesome thing about this hobby; everything is unique.

Marcoss, I think you comments are spot on. I wish there was some hard fast rules for corals, but instead it is just guidelines for lighting. The lighting part of this hobby is turning out to be the most difficult to figure out and I don't want to earn a doctorate in lighting to figure it out. I love my light I only wish I new what the corals needed so I can provide them exactly what they need. What I have read and the club meeting we just had has been helpful.

No, I dose Ca and alk (BRS two part) with a dosser and mag once a month. I run GAC all the time and GFO when needed.

I just observed my cleaner shrimp hovering/swimming over my zoa and paly area. The closure of each was like a domino effect. Some are still not open. Do you think something, I assume harmless in this case, is touching and agitatingn the Zoas? Could explain why some on the same frag are okay. Just an observation.

OK 3 AM check complete. I was up anyway putting third batch of water in the 210. I have these very little white dots that move on the two colonies that are not opening. They are like half a grain of sand in size. I thought Nudi's are bigger. Anyway I want to dip them in Bayer, will that work? Then do it about every 5 days for a couple of weeks.
Thanks for all the help.

They look smaller than any pods I have seen. And they are only on those two colonies. Like I say they are a moving white spec, about half a grain of sand and white in color. Are there pods like that?
