Two UFO's sighted for last month. Starfish?

These two (hitch hikers) have shown up in our 90 gallon tank about a month ago. We only see these occasionally, on the glass before the lights are first turned on in the afternoon. The lighting in both tanks doesn't come on until mid-afternoon, as we enjoy having the time to view the two tanks later at night. These are obviously nocturnal, or detest strong light.

Are these juvenile sand-sifting starfish? Or.. other "baby" starfish regenerating after being "mauled" before, or after, some "accidental" introduction to the tank (starfish can regenerate extremely well).

Look like some teeny-tiny starfish to me, but my experience with these critters were in the Pacific Ocean, a commercial aquarium, ..&...NOT a small reef tank. If these are starfish....are they desireable? Came in with live rock? Anyone have a clue as to what kind...or...or?

The finger shows how tiny these guys are at present.

Those are Asterina Stars. Most get rid of them. They can multiply very quickly and some kinds eat zoas. Personally, I wish I had them. My Harlequin Shrimp would love them!

howze01...Darn! Looked these guys up. Your I.D. was most helpful, albeit disappointing. Thanks, for the information.
