Quarantine debate: should I put him in the main tank now?

Maybe Im just being inpatient but I have a small pinky Goldfish that I was gonna put in buttercup (my big oranda) tank. It’s been like 2 or 2 and a half weeks and she’s been doing amazing. Pooping good,swimming around good and eating good. Should I risk it? Because buttercup means the world to me and I’d hate for anything to happen to him. I just feel bad cause the pinky is in a 5 gallon (all I had room for). Also I got the pinky from petsmart and you know how that goes lol... but I think I got a healthy fish
It’s maybe even been 3 weeks now that I think about it

 

If you think pinky looks great, I would put her in buttercups tank. But you might want to wait another half a week, just To be sure.

 

Lot of people recommend 4 weeks because it usually around the 3rd week is when stuff shows up. I am sure you can hold off. This is one of those things people do to prevent fish getting sick, as it is much easier to prevent illness in fish than to get rid of illness.

 

Well, ich completes its life cycle in 2 weeks, so most say that that's the absolute minimum amount of time you can wait, but think about the grand scheme of things, just waiting another 1 and a half weeks, could save the other goldies, I'd just wait personally.

 

Thanks guys I’ll just wait
