Watching the fish for 5 minutes before you buy it doesn't really tell you much, not to mention a fish bought over the Internet sight unseen. And all the proper nutrition isn't gonna help an already sick fish, especially one refusing to eat.
We can't say****** on here...At the end of the day, a new fish is like a box of chocolates... you never know what you're gonna get.
Maybe you get this hulk of a fish that is immune to everything or maybe you get a Typhoid Mary.
So, the sick fish dies in your DT and you bet the house that your existing fishes' natural immunity will keep them safe. I guess I see how that can work. However, I still feel it's a reckless thing to do when a couple weeks worth of passive observation in QT (no meds) would allow the new fish to pass away without endangering everyone else. Personally, I'd be ****** if someone purposely stuck me in the same room with a sick guy when an alternative was available.

We knew what ya meantApparently I can't get around the word filter (wasn't aware that word was censored).
A smaller frag tank usually works nicely. Just have an empty tank on standby in case the fish breaks out with disease.

For those freaked out by the concept of a bare bottom, rockless QT you can do passive observation in a Mini-Me of your DT.
That's a huge jump in logic regarding the reason why captive bred fish are less resilient than wild caught and basing it off of prophylactic treatment. The captive bred fish are less hardy simply because they aren't culled nearly as rigorously as 'mother nature'. Spawns of fish are in the tens of thousands per spawn. Of these one to a few actually survive to adulthood. Much more make it to adulthood in captive raised conditions. You will also notice more physical deformities in captive raised fish, this is not a function of immunity, but just less strict culling. Weaker fish make it through captive raised conditions, so they will have a higher mortality when confronted with pathogens regardless of immunity.Also, one of the links posted in the flurry above indicated that in an experiment, fish kept isolated/sterile can still pick up immunity components from tank mates. (I wish I were fluent in immunity jargon....I know I used no correct terms in that statement...but the links above said it right.
Mostly for what it's worth.
Also FWIW, I will (re)state that at the store I worked at, we noticed distinct differences in immunity between captive-bred (predominantly ORA stock) and wild fish.
As part of our QT we ended up keeping the two populations isolated from one another and saw a big, permanent drop in mortality rates and mass outbreaks of anything among either population.
This tells me that the prophylactic treatments the captive bred fish receive aren't necessarily better than a healthy fish, they just produce different resistances.
(I'm sure the treatments are necessary in their process, and I know you were answering the question of whether treatments would render fish unable to procreate.)
Diet itself has a lot to do with this difference in resistance too.
