So today I bought three baby kenya trees for ! what a deal right? :)\r\nThey're pretty small (bout 1 inch tall when closed, 3 inches when open), so I had to rubberband them to some small live rock. I did this about an hour ago and none of them have opened. Is this normal?\r\n\r\n\r\nI also got a Xenia coral (little older), and it opened up pretty good. Not all the way, but a lot more than it was in the bag. that's why I'm concerned about the baby kenyas.\r\n\r\nAlso, how long does it take for the kenyas to attach to the rock so I can removed the rubber band?
