PETCO Acclimation Tips/Guarantee

I just purchased a new fish yesterday from PETCO and decided that for those of you that have PETCO stores in your area and wanted to know what their aquatic life policy states upon purchase then here is their acclimation tips/guarantee written word for word...

-Before adding new aquatic life to the aquarium, float the bag on top of the water for a minimum of 15 minutes, no longer than an hour to allow the aquatic life to adjust to the new water temperature. The water temperature in the bag should be the same as that of the tank prior to placing the fish into the tank.

-Aquatic life, introduced into an established tank, can carry disease and/or may become aggressive or be attacked upon its release. Change or move the decor to alter the established territories. Feeding established fish prior to introducing the new fish may help alleviate potential aggression in the established fish. PETCO will not refund or replace established aquatic life that have been injured or become ill as a result of introducing new fish.

-In a properly established habitat, we guarantee our freshwater fish for 15 days from the date of purchase. A receipt and water sample is required for all refunds or exchanges (please see store for details).

-There is no guarantee for saltwater fish or other marine life. These animals have unique requirements, and are very delicate. They are not recommended for the beginner aquarist.

-PETCO provides a care sheet for all our Aquatic Life Care sheets are available from any associate in the store or at www.petco.com

I can't say I totally agree with what they have written here, how would they really know if it was "established aquatic life" unless you told them? Also, what good does a water sample do when you could have changed the water the fish was in prior to returning it? I am also not totally sure that within 15 minutes the water in your fish's bag could have adjusted to the exact temperature in your tank. PETCO should have healthy aquatic life to sell to people so I do not understand why it says: "can carry disease" who would really want to buy fish from a store like that after reading this? Luckily I have 15 days to return my freshwater fish if need be.
