Too Close?

My ric rock is at the top of my tank so they're as close to the lights as they can be. The only problem is I have a Hammer coral below them about 3 - 4 inches, I have never seen the Hammers sweepers come out...even during the middle of the night (it actually shrinks right up to almost nothing at night), is this still a dangerous situation for my lovely rics? I don't know where else to move them though as they will definitely be farther from the light if i do move them.
 
I don't know where else i can put them in my tank where they are close to the light but not close to another coral. I've never seen that Hammer sweep and it is pointed down and away from the ric rock so I'm going to hope that that's enough distance as the rics are doing extremely well where they are.
