This popped up in my tank seemingly overnight. I can't really take a better photo, but it seems to have attached itself to my frogspawn and rock.

From the photo I see it look like strawberry / ball anemone, can you match it on the photos to confirm Please? And if can post another few photos (different angle), to can get better few ?
