Blue Kiss Zoas Dying...

Hey guys, I bought Blue Kiss Zoanthids about 2 months ago. At first, they were doing really well in my tank, but over the last month they've been going downhill. It looks like the polyps are rotting away. One by one, they just sort of disintegrate. Today there were only two polyps left that open up.

I let my Alkalinity go out of check recently, and it dropped down to 7dkh. Over the course of the last few weeks, I've raised it back up to 10dkh. It is the only parameter that was out of check. Also, I don't see any parasites on the zoas. I dipped them in iodine today just to be safe, though. It doesn't make any sense; all of the other zoas in my tank are thriving. Any ideas? Suggestions? Help?

Here is a pic taken a month ago:

Here are two pics from today:

There's one candy coral frag that's bleaching a little, but it's never done well since I bought it a year ago...

Everything else if perfectly fine though...
 
what did you bring your alk up to...and how long did you take doing it...? Didn't think zoas were that sensitive to alk changes.......but?

I, unfortunately, have had the same thing happen to certain zoas and palys in my tank for no apparent reason.

It seems like whatever got your palys is the same thing that's wrong with my zoas...:grumble: Wish we could figure out why this happens, though. Today the Blue Kisses are almost all gone...:HELP!:

Have you tryed moving the frag around the tank to see if a different spot would work better?

Not until yesterday. I didn't think location was a problem since they had been doing so well where they were up until a month ago...
 
Sorry to hear about this Samantha, I got about 10 different zoa frags 2 weeks ago and for some reason it seems like only the ones with any blue color in them are melting away in my tank.
 
It sucks, doesn't it? I can't find anything wrong with mine. Just staying closed, and melting away. It makes me so sad because I can't do anything about it!! :cry:
 
Sorry, but it happens to all of us and most of the time we don't even know why. Friut Loops are my nemesis and I can't keep them to save my life. Did you notice anything that may be eating them or any type of fungus?
 
There is this weird mucus looking stuff on the surface in my sump. Maybe it's related? It has been building up for a little while now. I haven't gotten my skimmer skimming efficiently since moving everything from my old 46 gallon to the 50 gallon. I assumed the "scum layer" in the sump was harmless and was just an indication that my skimmer needs some more fine tuning...

...I'll post pics of the mucus in the ID forum...
 
You may want to inspect them really well under Actinic lights. Look for tiny eggs thet will show up. If you finf them you have zoa eating nudis.

I've been watching them for awhile now, but I gave them a real good inspection last night with a flashlight. I didn't see any critters or eggs...
 
Most of the less common zoos and palys come from deep waters you should try to put them in a cave or under an overhang where they get less light also deeper water contains more bad stuff in the water, in the ocean algae filters the water and sunlight only penetrates so deep so the deeper waters have more ammonia nitrite nitrates and phosphates in it. so with all of us striving for perfect water and all most of these deep water zoos, can't handle perfect water like most other corals can't handle contaminated water. when you do buy these rare deep water zoos and palys you should make sure that they are aquacultured so they are used to being in clean and well lit tank, Hope this helps

I just moved the zoas under an overhang. Maybe it'll help. :dunno:

However, I tested my Alkalinity before I did the WC about a half hour ago, and my Alkalinity had dropped back down to 7dkh over the past three days. Does this just mean that my corals are sucking it up to make their skeletons? I've never had a problem maintaining my Alkalinity like this. Typically a WC of 6 gallons with a tsp. of baking soda once per week keeps it steady. Any comments/suggestions? :?
 
have you checked your calcium and magnesium? The stability of alk level is highly dependent on other ions in the water being within the right range.

sorry about the zoas, that sucks. I wonder if the scum could be indicative of chemical warfare between your zoas... I have no idea, just a thought.

Calcium is on the low side, too (360ppm). I don't know about magnesium, though (no test kit).

I don't think the scum would be zoa warfare, because the Blue Kiss zoas are the only ones that aren't doing well...
