There are some green zoas and 2 white sponges on the rock in the first picture, but there are also long (2" - 3") rubbery tubes with what looks like tiny fluorescent feather duster heads coming out of them. They're tiny so it's hard to see if the crown is smooth or feathery. Also I have never seen the "heads" retract into their tubes. The first picture shows the rubbery tubes best, the second picture shows the head / crown best, especially if you zoom. Tube anemones or some sort of coral?
