Algae or worms on bladder snails?

[u/carthuffer]

Got these bladder snails for free from pet smart 💀 I have them in a quarantine jug rn and am really confused to what’s on their shells. I’ll try to post a vid of it in the comments as well. I havnt seen any movement from it but it’s super hard to see cause of how small they are 😭😭
