Looks like a harmless ball anemone. Not a pest like aiptasia.

How can you tell the difference?

Oh I've seen pics, but to me the biggest difference was the color and this one appears almost clear, so I was wondering what other characteristics were helpful for ID.

The main feature that sets it apart is the white balls at the end of the tentacles. Also, aiptasia will typically have a slight brownish hue.
