I have an outbreak of ich in my DT and need to move my fish to a QT for 8 weeks for treatment and to allow my DT to sit fallow. I'm worried that it will be impossible to keep my mandarin feed in the QT. I know we don't normally have to worry about our mandarins succumbing to ich, but If I leave the mandarin in the DT during the 8 week period, will it act as a host for ich even without obvious symptoms?
