Unkown filter feeder on snail shell

[Tripod1404]

Hi everyone, I just discovered one of my cerith snails have two filter feeding hitchhikers on its shell. I attached a video of them. One of them looks like a fanworm (creature to the left). However i was unable to identify what the other one is (the one to the left). It constantly takes its feeding apparatus in and out. It looks somewhat like a micro barnacle. Do you guys have any idea what it might be?

Looks like a tube worm (left) and little barnacle (right)

Sure thing

The barnacle probably won't get any bigger, but the tube worm will slowly grow in length. They're neat hitchhikers.

I found a hermit crab at the beach a few years ago that had a tube worm growing on its shell out between the crabs eyes. Like a unicorn. Lol
