Anemone Splitting?

[tgrover]

Does anybody know how long it takes for an anemone to split? I have a good sized, healthy Seabae anemone and over the last 2 days he has turned over onto his 'face'. His white body is exposed for the first time and it seems like there is a small seam down the centre.

I'm curious to see if anybody else has seen this. and how long it takes.

I am also worried that something is wrong and if so, what should I do?
