Ok so I've done a quick read through on the sticky for treatment and what a heteractis magnifica is. I would also agree that is probably a correct Id. So for the decision of whether it's sick or not. It is very responsive to touch, holds tight with it's foot, has slightly bubbled tentacles, it's mouth is slightly open, the water it came in was clear and clean although a little cold, the color doesn't seem to be off but I'm not experienced with that, and finally it did deflate when I first put it in the tank after floating for 30+ minutes and then dripping for 30+ minutes but it hasn't fully deflated since.
Honestly I wasn't really concerned about health until you guys said something but that could be my lack of knowledge showing with these anemone.
