good or bad? I've heard mixed reviews and it's the first time I have saw one in my tank.

Asterina star. You will hear conflicting reports. There are many species in the genus Asterina. I have watched them eating mushrooms and zoanthids. Some mess with coral some do not.

+1 asterina starfish.
I don't like them only because I keep my tanks really clean and without a "food source" they can eat soft corals and sps.
Some people don't have an issue with them but it's hard to tell the good ones from the bed so I pluck them when I see them.
