anenome problem

I have a tank that has had its ups and down, but it’s been up for a year now and I purchased a seabae anenome about 3 months ago. It was doing great, it was sticky, open and inflated looking happy and eating, but then about 2 weeks ago it decided to go for a walk and ended up in a power head...

Hi everyone, Just had a close up look at my anemone and noticed this little fluffy ball thingy on it that seemed to be moving, tank was started with live rock, is it likely that this is a little nudi? Any ideas if they are good or bad? Pics are below, thanks
