why do my finger and toad open and close??

[TonyOrlando]

i have several corals in my tank, last week i added a spaghetti finger leather and a green toad stool. My question is is after day 2 ive notice them opening/bloomng and closing/shrinking several times thruout the day. They look very healthy. Is this normal or should i be concerned?

they are porbably getting used to the lighting.... i say give them time and see what happens... maybe a solid week or 2.
