There are two or three big chain pet stores near my home and for the most part, it seems as though the larger animals and critters are very well cared for, but one of the stores is always getting in trouble for how it treats fish. They cram close to 100 tiny fish into one tank and then they act surprised when they all drop dead. To make matters worse, they don't clean the dead fish out with any regularity so there are tons of floaters, blocking the live fish from getting to the surface to eat. Ugh. It's disgusting.

You'd think that you have a tank with two discus fish in it and one of them is dead, if you hope to sell the other fish, you would pull out the dead one. I don't know about you, but when I'm looking for a healthy animal, I'm not going to pick the one circling a floater.
