Two Picture ID's

The title is misleading, i am pretty sure these are a brittle star and what appears to be a sea star? Sorry that the pictures aren’t the greatest

I haven’t seen the sea star before however it looks like it hasn’t finished growing three of its legs? Any issues with my corals?

The brittle star as you can see by the photo is right behind my feather duster and below some mud polyps - i have only seen this guy a couple times and it appears to be a lot bigger each time, although that could be my imagination. Tonight it was grabbing at the feather duster and holding for a quick second before the feather duster retracts...again any issues here with the feather duster or other corals? Not that it would be possible to remove....but food for thought

Thanks,

 

Looks like some sort of brittle starfish and an asterina start, nothing really to worry about with either(I think), although I have personally witnessed an asterina eat a small(TINY) kenya frag in my old 55. I try and pluck them as I see them, but that's just me. Was the brittle a hitchhiker?

 

Try this:
Starfish: Saltwater Sea Stars, Brittle Starfish and Red Sea Star

 

Yes it must have come in on some rock

 

brittle and astrina brittle has long legs and astrina is the small one that looks like leg got cut off. I would only worrie if astrinas numbers increase then pic them off like nano says.
