Quarantining New Fish and Medicating Display Tank

[Larry]

My question is about quarantining fish.

I'm quarantining new fish with the Med Trio, but should I really be medicating my display tank as well?

Maybe only medicate the existing display tank fish for parasites since I don't really see any fish that are ill in the display tank.

Would this be a good idea, so that the existing fish don't infect the new fish with tapeworms when I introduce the new fish into the display tank after they are cleaned out in a few weeks in my quarantine tank/tub?

I can see this being a viscous cycle of infection between new and old fish. 

Can anyone give me their thoughts on this subject. How do you handle new and existing fish?

Oh and Amano and King Kong Red Shrimp were just added to the display tank, I didn't quarantine them hope they do ok.

And... the new fish being quarantined with the Med Trio are 16 Neon Tetras and 4 Sterbi Corydoras. 

   Thanks

I wouldn't worry about that. But better be safe then sorry. The most important part is that you QT the new fish.

I Qt  all new fish but I only treat wild caught fish for parasites and I just monitor for 4weeks before adding to my main tanks

If you quarantined that fish that are in the display tank when you got them there shouldn’t be need for too much concern. They should ideally be clean and healthy. You are quarantining the new fish, so when you add them they should be clean and healthy as well.
