Starfish id?

[ShaunV]

Found this guy today on my glass. It is very small, about 1/4 inch. I tried taking a photo but it is of the underside. I started the tank on 3/5/2012 and have not added any livestock yet except rock and sand, so it must have been a hitch hiker. Can anyone tell what kind it is from the photo or do I need to wait until it gets bigger?

Asterina starfish. They are harmless and will stay around that size. They do multiply fairly fast.

Thanks so much! I google it and that looks exactly like what I have. It seems like they only eat algae, however some may eat SPS. I do not have any SPS yet, but I will. Should I leave it be or remove it?

Your welcome! They are very common.
