Button Polyp Inverted itself??

Hey everyone.
My 20 high is just finishing the cycle (doing a large water change today as the official end of cycle) and I had turned my lights off for almost 2 days to reduce an algea bloom. Well the lights turned back on today and there is a hitchhicker zoo who was closed when they first came on and for some reason opened up to look this way...(picture below) Can somebody tell me if this is just because of the lights coming back on or is something wrong iwth him??

I had a few zoo's that were doing this a few months back. I had to change the lighting. In your case it was probably the two days without light. I'm not real sure though, I posted a question about it, but never got a definate answer.
