Transferring plants from contaminated tank to new tank?

Hey y'all; I've had a rough start to this hobby, with a mystery fungal illness attacking my Khuli loaches. I've moved all the remaining fish into a hospital tank and treated it using Tetra Lifeguard which seems to be working, however I'm reluctant to treat the main tank with the same meds due to the risk it poses to the shrimp. Fortunately my gf is going to trade my 20 gal for another, so we can rebuild from the ground up, but my question is this: Is there a risk of the fungal infection transferring over to the new tank if I move plants from the untreated tank to the new tank? Should I treat the old tank before I move the plants, and figure out something else for the shrimp? Tbh I'm running out of tanks to juggle between...
