Tiny filter feeder thing? Not a sponge..

This is cool, what is this thing? It’s small, like 1cm max length, and zoomed in it looks like a filter feeder. It moves, as in it actively reacts to water movement. I thought it was a worm at first, but I’m not so sure about that now. It seems fixed in position, like it’s attached to the plug.

Thank you! I immediately researched, pulled the frag, scraped the area clean, and freshwater rinsed the affected area. Hopefully I don’t see any more.
