OK, I know that we often slag the advice given at pet stores, and there have been a few stories told about overheard conversations that we wanted to jump into for the sake of the fish. Last night though I overheard one that made me smile! I missed the first part of the convo but the end of it had the salesperson explaining to a parent and her young children that goldfish can live a very long time, so long that she might have to pass it on to her grandchildren, and that they get to be a foot in length. When I saw the lady leave the store later she was carrying a bag with a few guppies This was a PetSmart. They don't know everything, but they're not bad!
