Is my Magnifica Splitting?

[Apoc68]

My H. Mag has been acting strangely since yesterday. I don't want to say it looks deflated but it definitely looks less plump than normal. This morning, the mouth seemed as if it was slightly turned inside out and now it seems like there's a bilateral fold along its mouth and column.

It definitely doesn't look as healthy as normal and for context, there is a M. Doreensis and S. Haddoni in the same 180 gallon tank that are doing just fine.

The bilateral division seems the continue. The lights would normally be off by now but I decided to keep them on to document as much as possible.

It is hard to tell from the pictures from the pictures. But, from the pictures, with the compact foot of your anemone, I do not think so.
When Magnifica split, they start by deflating a bit, looking poorly and dilated mouth. Then you will see a hole appears through the mouth. I can see rock looking through the mouth. Once this happen, the anemone start to move their separate ways, ripping one side of the "O" to form a "C", then the other side. Once there are two separate anemones, they started to heal and form the mouth again.
I took pictures and documented this in the early 2000 on ReefCentral. The photos are all in never-nerver land due to one of their server upgrade.
