I just notice this today. It looks kinda like a Hawaiian feather duster but with 2 separate crowns side by side n long black lashes that surrounds it. Then it also has what looks exactly like a butt body part of a spider In between its two Head that's quite large... Here's a pic. It's directly on the left of the bubble Algee on my octospawn. When I scare it it retreats back into its tube.. Freaky freaky thang.
