Leather Coral Question

Ok.. I have a question.. I posted a photo earlier of a leather coral that because it was shut down couldn't be identified. Well my question is this.. I discovered that it is only shut down when the daylight lights are on.. during the moonlights it opens up. All my other corals seem to be doing well with my lights/water parameters/etc. Is this coral just getting too much light? It completely closes up when the lights are on.

Please forgive the iphone pics. Also if you can help id it I would appreciate it.
 
Looks like a cabage leather. I have one in my 75. Mine is positioned on the bottom kind if in the corner. I've found it does better with lower light. Maybe shade it for awihle.
