Just like it is in a small tank.
Have you ever seen a single dead fish on a shore with ich spots all over? I haven't. The majority of folks in this hobby have seen ich at least once. So, with those odds, don't you think we would at least see a single fish in our lifetime, infected in the wild?

They are not healthy fish for long if they are in a confined space IMO.
Well whats your definition of a confined space?
Ich needs a host to continue its lifecycle and without one it dies off quickly. In nature the number of the 150 tomites from a single excystment that manage to infect a host is probably a single figure. The ocean is its own QT. No major predator to keep them in check? No more like thousands. Ich isnt a paracite that effects everything and theres still thousands of forms of life that prey and can consume ich which also is forming the balance i mention.

No ive never seen a dead fish on the shore line infested with ich for the reasons above, if there wasnt a balance like i mention then i would have and infected and infested are worlds apart. Now compare that to an aquarium.
In an aquarium it only becomes an infestation because 1 that attaches becomes 100+ and then thats where confined spaces become detrimental.

Just as the ocean is a much bigger place, so are the amount and size of fish in it. I don't think there is a shortage of hosts in the ocean.
Again, from experience, I have never QT'd aything and haven't had a problem with ich. I've even introduced ich covered fish, and they recovered in my closed system.

No. Just keeping them fed and keeping a moderately sized, non-aggressive community, along with never attempting to house fish that are too large or too active for my system has worked for me.

I could not agree more. For years in humans and even fish the effects of long term stress on the immune system is very well known. That is what makes the fish fall prey to parasites and infections. You eliminate the stress and the fish's immune system takes charge again and the parasites can't penetrate into the flesh.

I've read before tangs are not susceptible to ich in the ocean because they only stop to sleep and while they sleep any of the parasites drop off to reproduce or whatever and by the time those ich parasites are ready to reattach the tang gets up and swims away. Fish don't stay in one spot in the ocean long enough for ich to attach to them. And if they do they eventually drop off and then the fish is long gone before they have a chance to reattach so they have to search for another host. And think about it. Fish are still stressed in the ocean dodging bigger predators

But the ocean stress is short lived, not an ongoing thing, like a 4" tang in a 40 breeder. Also, do you think that all the ich parasites go through their life cycle at exactly the same time? some are falling off, while some are hopping on...
The tangs in aquariums only stop to sleep as well.

Greg, I never agrued that for second. Quite the opposite if you read any of my other posts. Of course the fishes ammune system helps to an extent as anything living has to have one, even plants or everything would just die off. Regardless of that, heathly fish have a hugely greater chance at resisting but can sucumbb to the paracite ich if an unchallanged infestation breaks out from un-QTd fish.

I disagree, for the record. I have seen the opposite.

Well example: adding 6 heavily infected fish to a super healthy tank with a super healthy single fish. Forget about stress caused by the new additions and without any form of intervention, do you believe that the existing fish would resist ich completely or slowly weaken and become a host itself?
