Help ID my new budding coral heads

[LtDster]

I picked up this guy on the left from a LFS about 4 weeks ago and in the last few days I have noticed two heads of the light pink tentacle looking sprouts coming off just to the right of the lagre polyp. Im not sure if its the same species or something new. Some identification help would be greatly appretiated.

That's aiptasia. It's a major pest anemone that you want to get rid of asap

What is the best form of removal?

Aptasia x, berghia nudibranch, peppermint shrimp, file fish are the ones I've heard of
