What's Wrong?

[dodgersfan]

some of my zoos are retracted and i dont know why? everything around it seems to be fine?
are there any solutions to this answer? something that may commonly happen or whatnot w/o having to give water parameters?
thanks!

Posting water par. is probably the only way to determine cause. Some are open, some not.

 

[shnabbles]

How long have you had the zoos?
But ya youll need to post some water peramiters.
And any recent tank problems... Temp Spike stuff like that.

 

[dodgersfan]

hmmmmmmmm...........................ok
pH - 8.4
Ite - 0
Amm - 0
Ate - 15
Ca - 400
Phos - 1.5
there was a slight spike when my anenome died, but that was about a month ago?

 

[shnabbles]

I meant a temperature spike... Whats the tanks Temp? I had a fan go out on my for a day and the temp jumped up to 90!... Zoos closed up and eventually dissapeared.

 

[dodgersfan]

oh, i thought u meant a Temp (orary) spike :hilarious
but now that i think of it, i was messing around with the chiller a few days ago and i think the temp went up a few degrees. do u think that could be cause?

 

[shnabbles]

just a few degrees probally not....

 

[dodgersfan]

anyone else???
do snails or anything else eat these? maybe they're just being harrassed?
i know this has prob happened to someone else! please..............

i catch these lil buggers munching away on my zoos from time to time and i have to pic them off using tweezers they can multiply fast and demolish a colony of zoos easily
they are zoo eating nudibranchs and come in a variety of colors and shapes mine are like the size of a grain of rice and usually green or orange

 

[murph145]

ive also had some that have died off after acclimation maybe from stress or some other factor but they usually rebound pretty fast they are very hardy

 

[drew2005]

Your phosphate is kinda high. Should be between 0-0.03. 1.5 can effect coral growth. are you using tap water?

 

[dodgersfan]

nope, Reverse Osmosis all the way...............
i dont understand why the zoos are shrinking though, arent they supposed to be one of the hardiest? all the other corals are thriving! im guessin someone's eating away

 

[teresaq]

Take a small bowl of fresh r/o water and dip them in, ans swish around, and see if any nudis fall out. I found two on one of mine yesterday, I and soooo

mad. Now i am going to have to watch all my zoos and do dips on them to make sure there are no more. but where there are two, there are more.

 

[dodgersfan]

hmmmmm, that sounds like a good idea

but........
i glued my zoos down b/c the snails kept knocking them over. so they aren't comin off or out.

 

[feixjai]

how long had you had those zoos? do you have cleaner shrimp? my cleaner shrimps go over my zoos and polyps all the time making them close. or a fish could have swam close to it

 

[dodgersfan]

ive had them for about 4 months or so.........they were spreading like crazy until now! i dont have a cleaner shrimp, but i DO have a coral banded...........he does seem to harrass some of the other corals

 

[puffer32]

I had the same problem, couldn't see anything on my zoo's, but finally saw a sundial snail deep in the pods, then after close inspection found another one! Look close, might be your problem!

This Is a pic Of the Sundial Snail. VERY deadly for Zoas Get them out or your Zoas are dead. I had a nice colony of Zoas that died cause of these.

 

[dodgersfan]

that's a cool lookin snail.................but i dont want a zoo muncher!
thanks all for this info, now i have some things to look out for.................hopefully ill find the cause to "The Mystery of the Dissapearing Zoos". i hope to lock some snails away in prison

 

[smarls]

First, very pretty zoas...those are nice.
It is kind of hard to tell from that picture, but it looks like some of the zoas are getting a little "fuzz" on them. This may be the start of some algae growth, which is quite probable given your phosphate levels.
I am not sure what kind of flow they are in, but zoas do not like algae on them, and it causes them to close up. So if they are in a low flow area, you may want to try blowing them with a turkey baster to remove some of the build-up, and repeat this on a fairly regular basis.
You could also try moving them to a higher flow area, or changing the directions of the power heads to get them some more flow.
If I am seeing things in the picture, and they do not have any fuzz on them, then please ignore this entire email except for the first sentence!
