Anemone had twins??

[Piscez]

Well got up this morning to see how my mated black ice and black clowns (thanks timbits) were doing in their nano now I've moved all my other fish into the 220gal. I'd left an anemone in with them and once the other fish were out the male clown within the hour started to host it, which they never did before, anyway low and behold the anemone split! This has happened to me 5 years before when I was in the game previously but this time it split into 2 separate entities ( 3 total) over night!! Is that common? Or iis it as common as people having twins?

I'll try to post a pic later when my lights come on and if they come out from behind the rocks.
