You should have QT'ed them. Always QT everything!
If those fish have Velvet, by the time you know, it will be too late.
You should be watching them for signs of infection in a QT, not in your display.
If they end up having ICH, you'll have to go 72 days fallow to get it out of your DT.
If they don't, you'll be lucky and know what to do from here on out.
TTM on all fish reguardless if you see symptoms or not.
Flukes are easy to miss, and Brook can show up 3 weeks later.
Good luck!
