Understood, put myself in a bad position, tried to be the hero, not utilize copper in display tank any longer, and tried to do the unthinkable...use a 100 gallon tub for too many fish.
I understand the life cycle, and realize the methods people employ. My question is, is ich always, always, always, reproducing and out and about. Perhaps an example will help illustrate my point..
You have a brand new, tank. Completely sterile, and cycle it 3 months, using ammonia. You acquire your first fish, an Achilles tang (in reality, this would not be a first fish, but using it to shine my point). You place it quarantine, nice 40 gallon, well cycled tank. You go 6 weeks in copper, and after no signs, place in display.
Here is where I get confused, even though this fish was a carrier, (assuming so) did it fall off in quarantine, or try to, and thus, you broke the cycle with copper and didn't allow it to exist?
Or can you do the same scenario, the ich laid dormant, non active in the fish, waited out the 6 weeks of copper in quarantine, now to only go in display tank, and show itself 6 months later?
Assuming this is the first and only fish in the your display, is it guaranteed to spawn in qt, or could it wait months upon months, to begin its dance in the display tank, 7 months from now?
If not, and if it always has to fall of fish in order to sustain its existence, if that's the case, wouldn't TTM, not using drugs, and only lasting 12 days (14 maybe?) be the home run way to go? You would not have to worry about a bio filter, changing water every 3 days, thus no ammonia. And if ich is always trying to fall off, wouldn't this stop it in 12 days?
I guess I am not understanding if ich have to succom to quarantine upon arrival? Can it wait until a later unannounced time, and then do its thing?
