I guess you can say I quarantined mine in the main display , and my LFS guy is the only one I will trust. That said from what you say then QT for 7 weeks is not enough ?Insanely important right now
I'm not being facetious when I say that fish coming from wholesalers and LFS are utterly riddled with disease.
Ich is so common that you're probably introducing it within the first few fish you buy unless from a strict QT vendor.
It will sit in your tank and be fine for months or years until it finds a patient zero and overwhelms the tank and starts to kill half or more of the population.
Velvet is rarer but will wipe your tank out in weeks.
Uronema and Brook will be very common in certain species.
LFS/wholesalers are doing things like low salinity or sub therapeutic levels of copper which result in fish appearing fine and then bringing these parasites home.
You either QT your fish now, or you QT them later after catastrophic losses, or you exit the hobby due to catastrophic losses.
I think Ich is by far the worst of all of these - because it's ubiquitous in the hobby, and also blows up to be extremely deadly
And all you have to do to prevent this from ever entering your tank is by running a simple 14 day copper protocol followed by some observation before it goes into the tank.
Easily done with a cheap 10g, cheap 10g heater, some cheap copper and well tolerated by almost all fish - including the ones people claim can't tolerate copper (Mandarins - hobby myth)
