How long can corals survive cold weather?

[kupadupapupa]

I had my order dropped of at my door today at 9:30am and it was approx 50 degrees out. It sat out until I was able to get them at 11am.

After putting the corals in my tank they look good except for the one torch coral which isn't fully expanding. The other torch is doing great so I'm hoping the cold water didn't take a toll on it.

Do you guys think this torch will pull through or did it sit too long in the cold? The picture was taken after it has been in my tank for a few hours. I'm just worried because I just recently lost a torch due to shipping, seems like they just don't ship well at all.

Time will tell better than any of us can answer.

Dropped one on the floor once....concrete floor....and the cat wacked it. It recovered and growing well but it took 2 months.
Torches or frogspawn or any from this group do not ship well at all.
Give it all the times it needs and do not move it around the tank.

They will be fine as long as your water is good. They are very hardy.

Ok thanks. So far it extended a little more but still not as long as the other torch, hopefully it will come through.

Can any of you tell me what this might be on the torch coral? It looks like 2 deflated beat up tentacles to me. I tried to suck it up with a turkey baster but it just disintegrated everywhere.

After blowing some water at the torch coral there is no more of this stringy stuff. I fed it some mysis for the past 2 or 3 days, is it just expelling waste?

THe stony part of stony coral is slower to heat up and to cool down in such a situation. It may take a while to warm up, but in most things living, slow change is better than rapid.

It may have been spitting up some zooxanthellae, which corals do when upset with lighting or change. These are the microorganisms that help produce sugars from light.

That was one of the things i was also thinking because it's at the highest part of the tank. Although not directly under the pc lights but they still probably receive quite a bit of light.

Did the packaging of your order come with heat packs?
If so it shouldn't be much of an issue if the box was left out for only an hour and a half.

 

[kupadupapupa]

It did come with heat packs but it's already been in my aquarium for a few days. I just noticed the coral doing this today.

Following along. Good luck!

Also wanted to note, when I order live critters to arrive on a work day I have them held at a FedEx or delivered to a UPS Store (depending on carrier) that's on the way home. That way they're indoors until I can get there.
