I just bought my first xenia coral today (tiny thing since I know they can be a weed at times) and have acclimated it. I was wondering how long it normally takes them to open up, given the water conditions/lighting is correct?
Sometimes it can take a matter of minutes and sometimes it can take days, just depends on where you go the xenia, how it was transported, where you placed it, and sometimes it is just stubborn.
