Update:
A couple days back (mid QT tank Rally pro treatment), I decided to give the two fish the safety stop dips (formalin and methylene blue). They were both not showing any additional signs of brook, but they were eating well and I thought it best to get ahead of any potential issues. After the last day of rally pro in QT, I did a 100% WC and did a rally pro dip for 90 min. They are back in copper and doing well, hopefully next (and final) update will be when they go into the DT.
