me too...
i have just acquired some new zoas that looked fine in the parent colony but once in my tank they have what looks like a waxy sluff on them...kinda like a leather before it sheds..
i hope they are going to be fine...but i would like to hear any more info about his for sure..
i acclimated them for 45 minutes..other tank (seller) was .027, mine is about .0255, just below the.o26 on my refractometer...i treid something new this time...and floated them in my sump while dripping from the display...to keep temps normal etc..thought all was good..checked them for bugs...and shook them in freshwater bath...but two days now and still nothing opening..all the acros i got from him and did this too opened up just fine in a matter of minutes...no zoos yet though...hopefully today..
