Can you identify these two critters?

The first pic is a critter that just popped out for the first time. I’ve never seen it before today.
The second is down in a crevice in the rock but I’ve seen a couple of others and they have fleshy ridged tube bodies.

The first shot looks to be a Green star polyp, the second looks to be the dreaded Aipstasia, or possibly a Manjano nem.
