Flatworm? Snail? Something else - big bloom!

[Jon!]

Hi - these critters have bloomed all over my coral quarantine tank. One pic shows what they look like from the outside of the glass, the other shows what they look like outside the tank sitting on my Reef Roids container. Any ideas? I used Flatworm eXit which killed a bunch of stuff but these have bloomed a few weeks after. They have shells. Anything to be concerned about? Will my fish eat them when they go into the DT? Thank you!
