^^^ I really don't enjoy starting any conflicts or anything like that so don't take this the wrong way, cause that's not what I'm trying to do.
But why do you ALWAYS come off as incredibly condescending in your posts? I understand that quarantining doesn't rid the fish of all impurities, but it helps as opposed to just throwing them in straight from the store. And so does gut loading them, and treating for potential diseases. Its not perfect, as you've made painfully clear, but I've yet to notice any adverse effects, even on my 3 ~two foot peacock bass, who before i bought them ate exclusively feeder goldfish. So untill I do, I'm not going to act like feeder goldfish are some type of plague just because somebody was told by their cousin's grandfather that they hurt one of their fish. And feeding a fish 1 thing their whole life is generally bad idea whether its feeders or a good commercial food, and my fish don't exclusively eat any one type of anything.
I know somebody is going to post some link or something, but like I said, I'm not going to do something that has worked differently until >>> I <<< observe some type of an issue. Nobody else has to do it, and hell I don't even care if anybody "approves" of it. All I was saying was if your going to feed a fish feeders, you will avoid a lot of potential problems if you simply quarantine them and observe them to see if there is anything obviously affecting the fish for a week or two.
