Land planaria?

[Sesom]

Hey, sorry this is actually a terrarium question. in my paludarium I recently added some isopods, a snail, and some new moss, nothing big. Came back to check on them today and saw this worm. I believe it to be a land planaria. Are they dangerous? will they go into the water at all?

Land planaria worms will take to moisture but not necessarily go into the water directly. That said, if you only see one, I'd remove it as Land planaria do feed on mollusks ( among other things) so your snail is in danger.
