Heteractus magnifica without any shadow of a doubt. That is a ritteri/magnificent anemone. Not a bubble tip nor anything else other than H. Mag. If that looks just like your bubble tip then you own a magnificent as well, may have been sold under the pretence that it was a bubble tip however the seller was also incorrect. I have 3 of them personally and also just sold 2 bubble tips one rose and one green and that my friend is not entacmae quadricolor at all. No offense intended by any means, I however am a huge anemone fan so much in fact that the LFS's have labled me "The anemone guy". Fair warning that puppy is going to grow up to 3'.
Edit just saw the date, feeling more salty then my tank is right now.
