flatworm exit, or FW dip on shrooms ok?
They could have been on the shrooms the whole time without notice, depending on the type, though they like the light so they weren't likely hiding too far out of sight. But yeah, the cutting could have brought them out in force, I've seen them spread from fragging something.
Personally, I've done fw dips on shrooms without problems but then I'm paranoid about using chemicals in my tank, hence why there are still flatworms in my tank.
