Good or bad?
Not bad. Harmless filter feeders.
But I do disagree. I've never seen pineapple sponges look like that

Yes after looking up, while i appreciate the suggestion, they look nothing like the YouTube video’s on pineapple sponges or any sponges I’ve looked up….they seem to float aimlessly until they grab on to the rock or macro algae. Any other guess?
