The term "Aiptasia" as typically used in the hobby doesn't refer to a specific anemone as much as to all "pest" anemones; so colloquially, this would be "Aiptasia" - for an actual, species specific ID, you'd need clear, close-up photos of the mouth and tentacles at a minimum.

Regardless, it's not one most would keep in this case.
