I'd please. Good or bad?

Looks like a starfish?

That's an Asterina starfish. Some say bad, some say good. If they bother you, pick them out as you see them. If not, leave them be and they'll come and go on their own.

Asterina starfish. They'll multiply quickly in your tank. Good algae grazers but some varieties will eat polyps.
