WEll, you asked me. In my house I also lived with my wife, Daughter and her Mother for many years.
It seems this thread is coming to an end, with no real end in sight. It's early and I am waiting for my wife to get up so I have to keep posting. I will try to make something up.
We humans are getting very soft. If we get a little flu, cold, sore throat, mononucleosis, phemo thorax, Plague, gun shot wound, Malaria etc, we go to a Doctor. I had an Uncle who died about 90 years old who never went to a doctor, dentist or paid taxes in his entire life and he used to say, "Doctors die too"
I can't argue with that even though he was a very ignorant man, but also very strong.
He worked at the docks in NYC and those days it was very tough. Getting stabbed and killing people was pretty common. But even after getting stabbed numerous times and wrapping the rag around the wound that he used to clean eels with he was never sick. Never got an infection and never took an antibiotic or an aspirin for that matter.
What does this have to do with fish? Well he sold fish but that is not the point. Those people who lived before us (he was born about 1903) were in much better shape than we are. They ate food that was right out of nature and didn't worry if it was clean or USDA inspected.
Of course many of them died but they didn't die from the things we die from today which is caused by too many antibiotics, and not enough real food or most of all bacteria.
His brother got run over by a horse cart and died from tetanus as there was no vaccine.
They died from injuries that they couldn't fix or diseases that they caught from other countries that they didn't have any immunity from.
No one was vaccinated for anything.
As a kid I played in the dirt like all kids did, I also drank water from a lake or stream. A kid would never do that today because he is probably allergic to water. Kids today are allergic to everything. My own Grand Daughter is allergic to seafood, dairy, some meats, beans, peanuts, and probably air.
When I was young I never heard of anyone being allergic to anything. That uncle of mine would walk on the seashore and anything that moved, he would eat, like M&Ms right from the mud.
Our fish are coddled to much. The sea is much different than the air is and fish in the sea are in contact with every infection there is. OK fish from the Caribbean may not be in contact with French Polynesia parasites as I don't know that. But the sea has been mixing since before Bernie Sanders first put on a Speedo and jumped in.
Seawater is an extension of the fishes circulatory system and if it's in the sea, it's in the fish. Fish were built to handle that. We humans are at a loss as we lose much of our ability to fight off infections and now rely on antibiotics and hospitals. WE don't eat food any longer with natural bacteria like we did for millions of years.
Yes of course sometimes that bacteria would kill us, but for the most part, it made us stronger.
If immunity didn't work there would be no people (or fish). Immunity is what keeps my fish, and all fish in the sea from getting sick. Not Prizapro or copper.
All we need to do is strengthen that immune system and not suppress it with anything , especially things like copper and medications. If you feel quarantining is the way to go, do that, but you are not doing your fish any favors.
I was at a picnic a while ago and our Daughter's friend was there with her little girl. The baby was on the grass playing with the dirt and putting it in her mouth. I told her Mother and she said, don't worry, she is just strengthening her immune system. I was shocked because even though I believe that, most people don't get it, especially Millenniums. We were made to eat dirt as most animals do. If my Grand Daughter did more of that, maybe she wouldn't be allergic to everything today.
I doubt our ancestors were allergic to anything except maybe Saber Tooth Tigers or getting stepped on by Woolly Mammoths. They killed small animals and ate them raw with all the bacteria and whatever was in that animals stomach just as our fish do.
For some reason many people who say they lost all their fish because they didn't quarantine, I believe them. If you are not going to keep the fishes immunity it was born with strong, it will die if you just throw it in a tank. Our fish need to be healthy and feeding dry, sterile foods is not going to do it nor is separating that fish from other fish and putting it with PVC elbows and feeding it sterile food.
This is true, but humans now live in cities and are mostly sterile and not exposed to all the things fish are exposed to. I rode the New York subway system for most of my life. The wooden hand rails are very shiny like glass from millions of people putting their greasy hands on them. No one cleans them and yet we all didn't die from infection. We New Yorkers have an immunity because we did that every day, but when someone from Oregon comes here, they will probably get sick.
Humblefish is a friend of mine and he also agrees with my methods, just ask him.
He teaches quarantining as that is another method and many of the people that go to him for help are Noobs with sick fish because they refused to get their fish in excellent health.
I am sure you did, you probably should quarantine because your fish are not very healthy and hardly immune.
I did:

I have been writing about this for decades and even wrote a book. I don't know what else to do. Many people just refuse to keep their fish healthy or don't have the time.
This hobby is very easy but we try to make it difficult. It's just human nature to try to do things the simple way like get a medication to cure something rather than to keep the fish strong so it never gets sick in the first place.
Just like this thread, people think "Not Quarantining" means to just buy a fish and throw it into a tank is Russian Roulette and it is even though I don't speak Russian but did go out with a Russian Girl for a few years. The people who do that will end up with dead fish because they don't understand the process of how to keep the fishes immunity up.
OK, I'm done, time to go out for breakfast on the sea shore someplace. We will keep at least ten feet from the water so we don't get infected by those flying ick parasites. My wife doesn't need that and I don't have enough copper and Prizapro to put in her bath tub.
This should be far enough back.
