3 questions (pests, and coraline algae)

[LaneBrain]

Hi everyone,
looking around my tank tonight I had these 3 questions... I think I know the answers

1) Is this a flatworm on my zoa?
2) Are these Vermatid snails?
3) Is this Coraline algae?

(see pics)

1. Photo isn’t clear. You could pull the frag out and swish it in a small bowl to see if they fall off, or take a small pipette and gently blast them off, or dip the frag and gently blast them off.
2. Yes. And in the first #2 photo possibly hydroids or maybe just algae.
3. Yes
