Quarantine Tank

[gregzz4]

I think the consensus of a fallow tank is past 9 weeks, and some even go 11, just to be clear of everything

Your QT will be dictated by the size of fish you put in it
Longer tanks are needed for swimmers such as tangs and rabbitfish
A 20g is fine for small guys under 2"

I'd stay away from copper as it shortens lifespans

Put them in the QT and monitor them for 6 weeks
If you like, after they are eating for the first week, use Prazipro as suggested, but after that, if it ain't broke ...

combining hyposalinity and copper is very risquy. I am surprised that the fish are still alive. It is hard to control free copper in low salinity.

I would not use copper for ick, it is way too strong med to cure ick and it is not necessary. Hyposalinity alone is enough and gentle on the fish. A one hour dip in Paraguard before introducing the fish to the QT, right on arrival after acclimation is a very good way to clean a fish right from the begining.

The two that made it are in a 33g tank QTing for the last three weeks with copper, high temperature and low salinity. So far they have had a huge improvement and are eating twice a day like pigs.

Always quarantine!
