Bubble coral smoking???

[cmack]

I just acclimated my green bubble coral to my tank and put it in. Shortly after, it appeard to be smoking. Is this bad? or just some form of adjustment to the new tank?

it it brown and stringy? if so it is mosk likely fine as it is the expulsion of some or excess zooxanthellae- or it it white, corals dont usually spawn in tanks but.....
