Just for discussion...

Last night my Xenia took a huge turn for the worse even though he had been fine hours before. All of a sudden he shriveled up and laid down. I did a test
Amm 0
Nitrite 0
Nitrate 0
Temp 80
SG 1.025
pH 8
Alk 12
Phos 0
Calc 400
So... I did a water change anyway and came to bed. I get to work and my SW friend was complaining that his corals all crashed last night suddenly and unexpectedly.
Do you think... I mean what are the chances that the full-moon can play a little havoc on a fish tank?

HAHA!, It WAS a full moon last night!
I try not to think about superstisious things but wierd things do happen on full moons.
My lunar wrass turned into a wolf. He's back to normal but there's a lot of hair in the tank now. lol.

i would think the full moon has little effect on a tank that can not get lit by the moon.
xenia is a tricky coral. there are some unknown things about this coral. it seems to flourish in tanks with less than perfect conditions. It also will live in some people's tanks with no problem and then die in others, for no distinguishable reason.

 

[kynekke]

erm.. I didn't mean the superstitious kind of full-moon.. I'm talking about the moon that controls the tides in the ocean and more scientific things than werewolves.

I dont think that the lunar cycle has anything to do with the health of your inhabitants. JMO Your tank set up is not a complete replica of the ocean inclusive of tides affected by the lunar cycle gravity etc etc.. I maybe wayy off on this but common sense doesnt dictate this to be true.

I've heard of xenia just crashing, shrivelling up and virtually disappearing.... only to just grow back from the base that was left behind. Has that ever happened to anybody here?
PD, hopefully yours will fully recover.

ive had xenia do strange stuff like that as well. one day cant stop them from spreading, the next they just seem to wilt and die off.
when you did the water change, was the new water added to a sump or anywhere near the xenia? they can be touchy like that.
hope they 'bounce back' from the wilting.

 

[perfectdark]

Yep I have heard the same.. it can do some really strange things. They are however iodine glutons. It wont hurt your coral at all to do an iodine dip. It might actually be a good ideat. Do you test for iodine? DO you add any? and how often do you do your water changes?

I believe the lunar cycle has nothing to do with how the moon lights anything up. I believe its based on the moons gravitational pull on the earth or visa versa at certain times during its cycle. Being the most extreme with a full moon and the least with no moon.. or what ever they call the start of a new cycle.

I would think that it was just a coincidence that your xenia took a negative turn when your friend's corals did as well. Without knowing about your friend's tank, it would be impossible to make any conclusive statements however. With that said, it does not seem that that would have any relevance, considering that none of your other corals made a negative turn (did they?).

 

[emm0909]

Just because a moon is more "FULL" doesn't mean it's gravitational pull is any greater. It weighs just as much as it does when it's a NEW moon. It's the positioning of the moon, earth and sun that is different with them being in much of a line w/ Earth in the middle. New moon the moon in in the middle.
Now that effect on an aquarium? I don't think it exists.

i had a bad experince with xenia...it was doing fine then all the sudden mine died and polluted my tank ugh some stinky stuff!! had to do a big water change... i don't wish this on anyone but i will never put that coral ever back in my tank.

 

[grubsnaek]

i had the white pom pom xenia and the silver longated xenia. both doing great. then one day both started to shrivel. the pom pom got wiped out. i had a huge colony. the silver xenia. shrunk to about nothing. then one day bang, opened up with more polyps. dont know how, when it was shriveled up the whole time.
did your friends corals go, or did the tank crash.

you like the pom pom? My lfs had a rock with 3 colonies on it. Looked nice, but wasn't sure what it would be like compared to my pulsing xenia..

not true, the gravitational pull has to do with daily tides, however the moon light acts as a cue for corals to spawn. This is why you can program those new LED solaris lighting systems with realistic moon cycles.
in the summer time, there is a mass spawning of many many corals over the a certain three day period of a full moon. it is 100% having to do with the season and the moons light.

Well then I stand corrected. I had no idea... learning is cool.
