No I'm thinking they are feeders and already compromised, then you didn't feed them which they probably havent eaten in quite a while already and you pumped them full of meds.
I get what you were doing. But in reality you are wasting your time and really shouldn't feed feeder fish anyway. The med dosing was for fish you are trying to keep as pets not feeders. When I qt fish I give them a day or two to acclimate and then I get them eating and fattened up. At that point if any disease has shown up I will treat appropriately, if not I'll continue to watch them for a couple weeks if nothing show up gen pop it is. Is that the correct way???? I dont know. But it works and I'm not just medicating to medicate. As stated multiple times above thats how resistant strains are created.
