Strange little coral, I D please

[Firepony]

Hello
Ok..I have been watching this little guy for a while now. Stays in the same place, it is the little tan/brown striped guy above the Coraline and to the right of the white mushroom. Best view of it is at 5he very end of the video. Sorry, phone sux at pics oh..and it seems to have 2 heads with a star at the tip. It also seems to "move" it's trunk sometimes.
Anyone??? TIA!

Are the two "heads" formed around holes?

Yes, like a star

It's hard to tell from the photos, but the "baggy" nature of the creature reminds me of a Tunicate (Tunicata sp.) as opposed to a coral or sponge. These are uncommon hitchhikers and filter-feeders (water enters one tube and out the other) that are closely related to vertebrates, with a primitive backbone during youth.
