It was probably inside the anemone for 10-15 minutes, luckily the LFS was close by.
The clown, a clarki, was very visibly disoriented and swimming jacked up, and not just fins tattered, but it's whole body looked ragged.
I wasn't sure it was going to make it, but it bounced back just fine after a couple days, both clarkis paired up, and took great care of that anemone.
