Starfish good or bad?

[seanpig]

I found this little guy today in my tank. I do have one sand sifting star thats been in there for about 5 months. Is this a nuisance star or is he ok? It kinda looks like my sand sifting one and im not sure how they reproduce.

Asterina stars nuisance imo multiply fast not sure if they eat coral but take it as you want

Some (with color) are known for eating Zoas. The solid white ones in my experience are harmless algae grazers.
