Most of the reason that the fish at Petco are terrible isn't even due to the employees. Corporate has rules for everything and it is really difficult to get around their policies. My sister just started working at Petco and has been trying really hard to see what she can do to improve the aquatics section but almost everything she wants to try is blocked by corporate. Also as a new employee, she has no clout. The only thing that will change corporate policy, according to her, is if customers will tell Petco that they want to see things get better. I know most of us here just go buy our fish elsewhere, but if a lot of people start telling them that they'd buy from Petco if the quality improved, there's a chance that corporate would allow them to make some positive changes.
