My son, 10 months, loves to watch the fish swim in their tanks at Petco. We finally decided to buy him a fish tank for his room. The knowledgeable staff helped us pick out the right kind of fish for our tank. We also learned how to take care of them. Examples: when and how to change the water, how much they should be fed, what to do if they're in distress. It was a great experience! I will definitely be going back to Petco for all my pet needs!
