Anemone ID Help

[dare2dv8]

Thanks for the ID. I've been reading up on Anemones and discovered pure white ones are not naturally occurring. It seems to be doing well though...bro in law had it six months before me having it a month now. Reading online some suggest if it hosts a clownfish like mine there's no need for additional feeding while others suggest a meaty supplement will be beneficial. Suggestions and opinions?
