Ok should i do an additional two weeks of quarentine? Theyre supposed to get out in 6 days hitch will be the last day i can get a replacement on the rainbowfish and betta so if i need to do an additional 2 weeks i was gonna get the replacement tomorrow.
probably would be best to QT longer if you had a death. I QT for at least 4 weeks...if something dies I continue it for another 4 weeks or as long as any meds needed are being used + a week....maybe im a bit paranoid ^_^
I usually quarantine new fish separately even if they are from the same source (have your new replacements separate from the ones already in quarantine). Don't want to get the new fish sick or the other way around.
if a fish dies with other fish in QT i recommend extending your QT time to make sure the rest are healthy, if you add new fish start the QT time over on the date of the new fish entering the tank.
