Starfish? Good? Bad?

[Michaelbknudsen]

Please help with this critter in my first nano reef tank.

Asterina starfish. I take them out however it's widely debated as to their ability to harm corals... They are seemingly ok in my tank, just more of a nuisance due to them reproducing and eating coralline algae...

I had some Eatting on a monti cap so I take them out I still have them and have not seen any harm my coral since but they do eat the algae good and bad

I plucked him, and his white friend just to be in the safe side. Thanks for the help guys!
