Looks like a asterina starfish. Harmless. Some get annoyed with them if the population gets out of controll. I would keep

I have a few all white that live in my sump... been there awhwile... wasn't sure if this guy was same or not

Just put him in your sump with the others.

Chuck it.

Asterina's will grow a massive population, and a selected few are not reef safe.. there is no indication whether or not it is unless you find out the hard way.
