Can an Anemone split at any stage in it's life?

[reefsaver]

Do Anemones split after they hit some kind of mature size, or can they split at any stage of their life?

 

[P-Dub]

Any time it wants to.

My rainbow was about 8 or 10" across and finally split a couple months ago. My rbta was about 4 or 5" and split. Stress or regular feeding can both cause the process.
