Maxi Mini Naturally Splitting?

[blueridgereef]

I've had this maxi mini since about May, and while I fed mysis weekly the first month or so, when summer started I got away from the weekly feedings.
A little over three weeks ago I got a rock flower anemone, and with two hungry mouths to feed instead of one I got back on track with the mysis, ramping it up to twice weekly feedings. I also did a 30% water change Saturday, and a little more on Sunday(I was bagging up corals to sell.)
I know both of increased feeding and water changes have been known to induce splitting, so I was curious.

Saturday it was the nice fat oval shape it has been the last few months-

But today it seems skinnier and 'pinched' in roughly halfway up-

Is it just having an off day? Or is this the start of a natural split?

I don't think those split.

I have 3 like yours and they always do that. Some wrinkle up like large carpets and stay that way. Maxi mini nems don't split on their own.

Thanks for the replies. You guys were right, it was back to normal again when I turned the lights on today. Wishful thinking I guess
