leathers corals not opening getting concerned...

[jorge0912]

i have a few leathers in my tank and all the sudden they closed up and have not opened up again..
getting concerned they are dying.
one of them is a regular toadstool and they other one is a green toadstool and one of them is a devil hand coral all three of them have not open for days .
i have a few other leathers and they all look fine... and also all my other coral is just those three ..
i did move the ligth a bit away towards the front of the tank but it looks like if the big toadstool is still getting ligth... here are some pics of them

Very common for leathers, they can stay closed up for a while... NO need to be concerned just yet. How's your tank parameters? Anything off??

Leathers close up and shed every so often as part of their normal process from what I've read.
