Maxi Mini Stung by War Favia
 

I put a frag of war favia a little close to my maxi mini and I think that the anemone got stung because it moved to the underside of the rock that it was on.

The mm seems to be healthy, I fed it last night, it took food and is still good and sticky, but it isn't getting an appreciable amount of light where it is now.

Is it going to come around on its own and move back into the light when it is ready?

It will. The beauty of them is they can move to any location that suites them best at the time. I have had a couple move too close to brains get stung and literally melt into a puddle of goo within days so sometimes their choice of location isn't the wisest.
