This is good news. As I was trying to explain ,if ICH affects even one fish in the aquarium, then all fishes in that system have been exposed and treatment of the whole tank becomes necessary or ICH will be present and can affect all fishes in the tank repeatedly.
So if ICH was present on the Columbians in the 75 gal, then all fishes will have been exposed and 75 gal would need to be treated to kill off the parasite.Simply moving the affected ones does not prevent parasite from affecting others .
Always good to quarantine new fishes for a couple weeks before introducing them to your tank lest they be carriers of pathogens unknown and inturn,, infect otherwise healthy fish.
