It's Petco. I don't even maintain mediocre expectations when I go in there. Nevertheless, I've found they are not all like the conditions pictured above and I have some very healthy fish I purchased from Petco years ago.
In addition, I could take pictures similar to the ones posted in the scores of local fish stores I've visited that should be expected to have advanced knowledge and care protocols.
Fish get sick. Entire systems can become inundated with parasites and sometimes employees don't notice dead fish. Or they do notice and are busy at the moment, used to pulling dead fish on a regular basis, etc.
Unfortunately, it's just what happens when people turn animals into an industry for profit. Whatd'ya gonna do?
++1 on this above. Our local petco isn't that bad, but there is a LFS semi-close by that has the worst looking fish with popeye, high prices, and they don't do a thing about it. Just because they are Petco doesn't inherently make them bad. They get a bad rap because they are a chain store, there are a lot of them and they are more visible than the small stores out there that many never venture into. Instead of slamming Petco constantly on hundreds of threads, just highlight general store practices. Ich is everywhere and if you really expect your LFS to solve all your ich and parasite problems, you have your bar set too high.
