What is this

[Gp!]

I just got an order of snails and some of them had growth I couldn't scrub off with a toothbrush. I had an emergency at work and had to put them in the water before I could make an informed decision. Any idea what this is and do I need to pull them back out?

Looks like ditoms or hydroids

Think I should pull it out when I get back? Had two like that. The others seemed clean

Here are two zoomed in photos. Not great but cell phone didn't want to focus

Hah he's a worker. I pulled them and put them in a bucket and the little guy is circling the other one like he's covered in something delicious. If they are eating I guess it isn't really a problem and I can put them back? What do you think?

No expert, but it looks like snails with algae. Mine are always eating it off each other.
