Although I understand you're bitterness on the subject, that's a bit of a generalization. i have had no trouble with the fish i've gotten from petco in the past. My neon tetras, which are supposed to do very poorly due to overbreeding survived cycling my tank and are still here almost a year later. I don't think it's fair to say they are abusive. Half the trouble is the difference in employees. I have gone to petsmart and petco (the only lfs around here besides walmart which isn't worth mentioning) and alternately seen tanks that were absolutely pristine, and tanks that were filled with dead and sick fish. I've been in petsmart and heard one clerk say "another dead fish? I just scooped four out of that tank this morning!" And petco, at least, has a hospital tank, which petsmart doesn't appear to have.
