Brittle Stars good or bad ?

[Opiy]

I have a brittle star in my tank (58g) and was wondering if they are good to have? And are they known to do damage to corals mainly softies ?

Thanks

they are usually fine, the only thing is green and I believe yellow brittles have been known to eat small fish...

green ones are bad "the green death"
