Every new fish goes thru .4-.5ppm cupramine for 3-4 weeks. + 1-2 one hr formalin dip.
even fish from DD(true personifer+achilles) goes thru the same QT regimen.
i have an achilles, pbt, and blue tang without ich. arguably the top 3 ich magnets. also a few angels.
So if i read correctly, you do 3 4 weeks of qt with cupramine, after that time frame an hour formalin dip? Then right into dt? Anything else before display tank? You listed some fish very prone to ich. Is cupramine as risky as copper treatments? I ask because ive never qt'd and never had to medicate, but its been a long time since I've had a tank. (not including effete snow storm in Oct that wiped out new tank)
