put shrimp in some panty hose theyll get stuck in it, but i have flatworms not bristleworms

do flatworms have shells? like a small flat one?

No. That might be a chiton. If so not harmfull. For your flatworms if you don't want to use chemicals and have room for another fish try a six line wrasse. They are evil little buggers over time. I have a potters wrasse that helped out in my tank and he's been well behaved.

i need to get a lid b4 a wrass, and they have little flat shells and anteni like snails

Those are chitons not flat worms, flat worms are fairly small and have no shell.

but the shell isnt seperated at all.... its see through so you cant see it

Those sound like they might be Stomatella Varia snails. They are harmless. I have tons of them in my refuge but none in my display something in the display is eating them but I don't know what.
