Need ID on sea star, algae, and others

[Gpsdrew]

Can anyone ID the sea star I found on my live rock. I would say it was a brittle sea star but it has 6 arms! Also there is some sort of tube thing growing on it along with a pink little sprout I think it is too small to tell but I'm not sure. Also does anyone know what this orange algae is?

Forgot the pictures. Sorry.

More.

The starfish looks like a brittle star. The arms vary I believe, but not sure.

Mini Brittle stars often have odd numbers of legs. Nothing to be concerned about. I've seen them with 2-7.

7 legs!!! that is a lot. Thanks. Do you know what the other things are?

Defiantly Mini Brittle.. I've herd there good to have.. The other pic is kinda hard to see but maybe some sort of tube for worm

Yeah, I can't get a good enough look at the "tube thing growing on it along with a pink little sprout" but that sounds like a mini feather duster to me. Just filter feeders.
"Orange algae" sounds like... well, orange algae. LOL Probably a low light species of coralline algae. I had a lot, but anything above the halfway point in my tank has vanished, to be replaced by pink.
