ID star good or bad?

Found 3 of these so far half grown stars about half the size of a dime . Wondering if their good or bad ? ( best pic I could get with my phone)

Well no image but there either Asterina stars (depends on type to judge good or bad) or Mini Brittle stars/Ophiuroidea, which are harmless.

O sorry that would help huh haha

Asterina, most likely harmless but if you have zoanthids and you see the star around the zoanthids rather than on the glass you might have an issue. The other draw back is that some types are prone to population explosions.
