Several small stars on glass

[CanDo]

Attached is a regular pic and a pic under a 10x loupe of a starfish on my glass..
I haven't scraped the glass in weeks, waiting to see how this plays out...
Any help? Please : )

Asterina.
Multiple quickly.
For me, a pest, just remove when you see them

Asterina star. Some people say certain ones can eat zoas. I've not had that issue. At times I've had hundreds on the glass overnight. Mine tend to self regulate the population after a while. I I don't know how they get in our tanks. My last tank was started with dry rock and they still appeared after a few months. I started picking them out but just gave up.
