Where's your live rock from. Cause I've got a few of those, and my rock is from the Tampa Bay area. What I've got are not aptasia but instead curlique anemone . Here's a site that for common Florida nems https://reefguide.org/keys/Sea_Anemones.html Also a picture in white light would help too.

Here is one I let grow that came from live rock from that area. About the size of a tennis ball.

Its aptasia and keep it simple:
Using syringe, inject either lemon juice or better yet. . kalkwasser powder mixed with tank water into a paste the consistency of toothpaste and inject into the very center core and it will melt away

Hard to tell from image. However, I had a bad outbreak at one time. There are a lot of things that people recommend to get rid of them. I tried all including reef delete (the reef delete is junk and if you buy snd it does not work from aqua cave kiss your money goodbye) except laser. Best things I found were aptasia eating nudibranch (best option but fragile) and peppermint shrimp. Have not had an issue since I introduced these animals in my tank. If they get in your corals and you try aptasia-x it will work but you will lose some heads. It is really important not to let them get out of control. Hope this helps.
