Help with Hitchhiker ID

[Tocspaw]

Hi I have a few hitchhikers on new ocean live rock. I would love some help with ID:

1) Tiny green anemone

2) looks like possible Aiptasia on the underside of the rock but does NOT retract when touched- could it just be some sort of algae?

3) Yellow round blob - is this a sponge?

White/neutral light would probably help with the identification. And maybe an arrow or a circle around the specimen you want to have identified (at least in the second image).

Aiptasia/Exaiptasia species retract when you touch them, so if it's not retracting I doubt it's an anemone at all.
