That is one approach. However, it is possible that even though they are not showing signs of disease or parasites they may still be carriers and bring them into the DT.So if you do choose to QT, do you automatically freshwater dip or treat with chemicals?
I have a large 40g breeder for QT, I also have a 10 and 20 if I have to treat fish. Right now I have a butterfly & a juv tang in the 40. I didn't freshwtaer dip or treat them & they seem to be doing fine. I was planning on leaving them in for 2 weeks and if no noticeable issues arrise, into DT they go. I didn't want to stress them out any more than the shipment did, unless I saw an issue.
