It sucks in when scared..aiptasia?

I've never seen aiptasia with bubble tips, nor heard of one. It could be a majano sp. It could also be a baby bubble tip. Years ago I was the lucky recipient of a baby rose BTA that came along on a coral from the LFS. It looked just like this. After target feeding and some growth it colored up and was beautiful.

I guess I'm saying that you may want to wait and see what it develops into.

It looks kind of like a harmless feather duster IMO.
