Cerith snail hitchhiker?

[AthensReef]

Hi all,

Picked up a clean up crew a few weeks back and just noticed these small white bumps with something darting in and out on the back of a couple Ceriths. I attached a small video, please ignore my sons cartoons in the audio, lol.

Any ideas??

Barnacles, harmless filter feeders.

How come I get aptasia and isopods hitchhiking and it seems everyone else gets barnacles and coralline? .
