Rose anemone split...

[Timbits]

Hi all, so my rose anemone decided to split into 3! After the split, it has been kinda hiding in the shade under the rock. One moved to the bottom of the tank under the rock. Is this normal? Are they just recovering or what's going on? It used to be at the very top right under the surface of the water loving the light. Its been a week now i think. Should I be worried? I miss looking at it...
