Identify Anemone ?

[RGA]

I recently purchased some coral which had this Anemone attached.

I have 2 common clownfish and was hoping it may host them, but I am unsure what the Anemone is and if they are compatible.

Any help appreciated.

The picture may not show the colours but the tentacles are pale green and it has pink tips at the end of them.

Looks like a BTA. does it have white lines around the mouth?
