ID critter, please

So a bigger one is in a corner of my tank, and a smaller one (pictured) was floating around. I saw my goby swallow it and then spit it right out.

I do have a hydroid in my tank - is this a juvenile?

This is the same thing (apparently) in the corner of my tank:

It's a ball anemone...good guy. More like a mushroom than an anemone.
