Ohhh, Zoanthids...

[EmilyXLC]

Well... I was out of town for the weekend & when I returned home, one of my small Zoa frags had magically disappeared. I can't even find the small bit of rock that they had been attached to. The dumb crabs are constantly knocking things over, so I thought maybe this got knocked over as well. I moved almost all of the movable rock & was never able to find it. : (My other frag has still not opened. They're still all balled up.All parameters are normal & I did a water change when I returned home on Monday. The other frags & my two clowns are doing fine. What is up?

 

[jeffthomas]

That is a mystery... Check them closely to make sure their are no pests like zoanthid eating nudibranchs. Hope you can find your missing frag and the others open soon.

Geez I hate that !!! Just give it some time and maybe it will come floating by.......

Even with glue, I still get frags knocked off. I have a frags removing machine in my tank aka my urchin.

I think there is a magic land (sea?) where critters go live among fairies and single socks.

Yesterday afternoon after 5pm I put a small amount of Rod's Food in my 2g tank and by bed time, the yellow-tailed blue damsel had disappeared. The tank has a lid that has a hole the size of a silver dollar (remember those?). I checked my parameters today and they were pH 7.8, ammonia 0, nitrite 0, nitrate 0, and salinity 1.025 and everything else seems fine.

Zoas are funny... i have a few different types of them and they all seem to act differently.. last month i got 1 hockey puck sized rock with 2 different types of zoas on it. one of them can't stop growing and the other one seems to be vanishing... I have yet to figure that one out, since i don't have anything that would be eating them!

Smaller frags have also disappeared from my tank... multiple times.. whether i glue them or not!

I've always wondered where that other knee sock went...Um, your Damsel is gone? Do you have a mantis in your tank or what?! LOL! Let's hope not... but maybe the Damsel going MIA could be a good thing.

I have had the same thing happen, had a good size frag of Pink zoas and orange ones...the pinks one just...vanished where the orange ones are still doing fine. Odd thing indeed...glad I'm not the only one.

 

[markkazdad]

Yep, the damsel is gone and today the peppermint shrimp either died or molted. I don't know how to tell the difference. We are away camping so I stuck it in the freezer for later. I guess it will be obvious eventually if it was a molt.

The only thing that I think I need to deal with in that tank (though I am sure there are others) is the slight "oil slick" on the surface of the water. Suggestions? I think I read somewhere I could blot it with a paper towel.

 

[EmilyXLC]

Whoa... I've never heard of such a thing. What in the world is going on with your tank?! : (

 

[OurReef]

If your getting an "oil slick" on the surface you need to get a pump or something to disturb it. You could have lowered oxygen levels in the tank. Disturbing the surface gives gasses a chance to exchange.

 

[WesW]

Markkazdad how is your surface agitation? I have a powerhead pointed at my water surface to create good surface agitation. It helps oxygenate the water and cuts down on the film on the surface.

 

[markkazdad]

I do the same thing. It is a very slim film. Less shimmery than a soap bubble in the sun. It has been that way for several weeks at least. I was guessing it was oils from fish food or waste.

Maybe I will angle it up a little more.
