Almost certainly yes i'd say. Alot are algae grazers but they can reproduce to plague proportions. If you only have 1 i'd remove it. Although more could pop up.

I agree deff an Asterina star I have loads of em the look a bit unsightly on the glass but a quick wipe and they are gone for a while till they climb back up,

but if you see one you can be sure theres more that you didnt see.

I would agree with removal on sight....brought in 2 or 3 several months ago on a coral and now removing up to 30 on a daily basis here....although normally harmess they become a real pain when they multiply

whats the best way to keep the numbers down.

whats the best way to keep the numbers down.

manually remove by hand

agree with rob, not much more to add, except even when you think there all gone, they suddenly appear again haha

[owlbassboy]

best way would be a harlequin shrimp but but you will need somewhere to move it onto after ts ate them all or be willing to buy stars for it to eat
