Sorry to hear that. Considering the speed, do you suspect Velvet? I would think it would not be Ich. Maybe a massive Ammonia spike. You should consider multiple smaller Temporary QT Tanks. While I'm not an expert on chloroquine, from what I understand it can suffer from biodegradation and there is really know wat to ensure it's at therapeutic levels. I believe I have never had a Fish die from CopperPower poisoning. I think many Aquarists blame Copper for their fish dying, however fail to realize it takes time to work and even longer if you ramp it up. It gives Pathogens too much time to overwhelm the Fish.
