If you kill Kenya its time to cash in your chips as a reefer. J/k
Kenya tree is durable stuff. sometimes it just deflates to clense itself, should re-open in a day or two.
did the new tank cycle completly what are your water perameters , these corals dont like to be moved all that much sometimes after a move they close up for a few days
I have a colt that does pretty much the same thing every once in a while if it gets bothered. If it doesn't open within a day or so, then you should worry.
