Turbinaria sp.

I've had the coral below for a while, it's hasn't really shown much growth but has looked, until recently, a healthy specimen.

This is until my starry blenny has decided to start using it as some sort of throne - as pictured below.
The polyp heads in the area he sits on have gone, and the colouration of this area has lightened.
Can anyone advise if this is having a detrimental effect on my coral as pictured.

I'm no expert, but this is from experience, the more flow and light it gets probably the better - probably the guest isn't making it happy.

I've just moved one from my old setup, where it wasn't doing well, to the new tank and the turnaround was fast. The lightening may be a sort of bleaching event. Mine went like that for a while. I thought I was losing it.

However, since being in the new tank it went a dark mustard colour with yellow margins and polyps. It seems to have grown some too.
