Is this an asterina starfish?

[ILMX20]

I only saw this guy today when I came home, there’s only one of them, but I have corals in the tank so I’m a little concerned if it’s an asterina. I’ve attached photos for reference, but if it is an asterina, what should I do with it? I’d feel bad if I had to kill it.
Thanks for all your help!

Yes, Asterina

Get rid of them early if you don't want them to multiple in your tank later!
Also some will debate on it, but I still belive that it's these little starfish who ate my zoantis

Asterina reproduce like crazy. I'd check your live rock as well to see if you have any there, they are sneaky buggers. I had an infestation of them and they killed off so many of my zoas until I introduced a few harlequin shrimp to the tank. They made quick work of them thankfully. Now I just have to make sure to buy a Chocolate chip every couple weeks for them, which unfortunately are very expensive these days
