Coral experiments
 

Tonight's experiment is simple


I'm going to fill a glass with saltwater and place a zoanthid frag in the cup then out in the bitter cold it goes for the night , tomorrow morning ill place the block of ice back in my tank and we will see if the zoa will survive it's currently -24 out side

Will take pics of the whole process



I voted will come back to life

that's just cruel D :D jk
Very interesting experiment, love to see the results as well.
Guess we can then ship zoas all over the world without heatpacks from then on? :wink:

Frag of blue zoa's is now outside it's so cold it should freeze in about an hour


I have high hopes for " lucky "

Lol , " lucky" hey? Hes gonna need it.

Looking forward to see the results

how about a side by side with some GSP and aptasia

experiment
 

the aptasia would survive

Well I gotta say I'm amazed

the coral this morning was a full block of ice and spent all night in the -24 cold I put it in this morning to thaw amd was opem with in an hour all polyps are out and open to my amazement this coral is going to survive amazing and surprising what a single coral can handle if put to the test

So I guess the question is now should I give it a try for a full week

Well my mind is blown even though I voted it would survive I kinda thought it would melt and not survive I mean it's way too cold for coral to be outside all night so now goes the question what extremes can coral be put through

Amazing, in addition to being frozen solid it probably also went through some wild salinity swings as the ice froze and thawed. Puts new light on the question of how to acclimate corals.
