Depends on the store and the employees it seems. For every bad story someone else has a good story. That is the problem with many big chain stores, they seem hit or miss. It also depends on the managment and how much freedom they give their employees. Since the tank will be for puffers only it will essentially be the quarantine tank. So watch them closely for the first few weeks after you buy them (it is hard not to as they are so cute). And really check out the tank they are in at the store and the tanks close by as most big stores use central sump systmes for their filters. So if one tank in the group gets sick, they are all effectiviely sick.
