Help me ID this hitchhiking Star

[John Mills]

Picked up some corals the other day, and this guy came off when I was dipping them. Not sure what it is. It's tiny, maybe 1/8th inch total.

asterina i'm guessing.

 

[reef lover]

Yup

Good or bad?

 

[ThunderGoose]

Good. Although sometimes they can over-reproduce and need to be thinned.

Good or bad?

It's almost impossible to tell the good ones from the bad. Some eat coral, some eat coralline algae.

I had some that I caught eating my utter chaos and rastas. I took them out via harlequin shrimp. My favorite tenant [emoji4]
