Help with my bubble anemone!!!

[RH~reef]

This anemone came to my fish tank about a month ago, I took it out of a friend's fish tank the same day that the mother divided, with the passing of the days she joined her mouth and everything (I have not fed her yet) ... The last week he has taken this ball out, I do not know if it is the foot of the anemone or if it is something else, the truth is that from a moment that the anemone enters that small hole in the rock, someone can help me see what my anemone has? it has not lost color or anything
