Help me ID these please

The first picture is some type of starfish I think. It looks blue or gray in color.

The second picture is of some weird light green dots that are popping up everywhere in my tank. They are on snail shells, equipment and rocks.

Hmmmm....not for sure but could the dots be green coralline algae? I have heard of it but never seen it.
