I'm not really sure whether to buy my fish from the local family owned aquarium store or a big chain store. The big chain store has a two week guarantee on all of their fish. The family owned aquarium store has a very knowledgeable staff and a great variety of fish. I usually buy at the chain store rather than the family-owned business because they have a two week guarantee which is really helpful to a new tank. I'll usually call the big chain first, and if they don't have the fish, the family owned business will usually have it. The family owned fish store has a higher quality of water in each tank compared to the chain store, but with the chain store, I can just replace the fish if they die. What do you guys think of this?
