Odd question About coral...

twintrades · Apr 11, 2013

How long could a coral last out of the aquarium ? For example if one would take out to frag and forget it was out for a couple hrs? Would it be dead? Or is there a possibility it would survive ? Were talking in the house not out side and no blasting light just room light.

I know coral sticks out of the ocean when the tide is low. But dont know how long.

whats your guess?

Some corals are shipped from overseas with no water, it's better than having elevated levels of ammonia in the water. In the ocean where corals a sticking out at low tide lasts for around six hours and some of them are in the blazing sun.

Really depend upon what type of coral you are talking about.

When I do water changes most of my SPS is out of the water... They get angry but sliming up I feel is good for them once in awhile.

In the ocean they are out for a long time, but they have the ocean there with pristine quality water. I never really tested how long they would last in an aquarium setting and to be honest I don't intend to do it either...

It's best to keep them in water, but occasionally it won't hurt them.

I was thinking the same as you guys. I didnt know that some suppliers ship them out of the water tho thats interesting.

I was mainly talking about sps But also lps and softies. Just was a general question. But now im wondering what would hapen to lets say shrooms and Lps. DO they ever sun bath at low tide ?

I also let mine get exposed when doing water changes. My xenia is not phased at all. I have many different corals and have never had any issues, but it's never for more than a half hour. Ever 3 or 4 months I disconnect one of powerheads from it mount and with it in my hand I blast everything in the tank. It's like a artificial storm. Everything seems to perk up the next day.

I would say the humidity levels in your house can make an impact on how long they are left out....

I don't have an answer to this, but I would think that if it was fragged already it is stressed and would be more susceptible to anything in a stressed condition.
If you took it out to frag it and never did it then the time out of water would be expanded.

Hmm thats what i was wondering.

Here some pictures when I did a water change, last night. The corals were exposed for 15 minutes. When started filling the tank back up. The last picture you see everything open with polyp extension. It took about 10 minutes to fill tank. Last picture was about 6 minutes after the pagoda cup coral was covered with water.
