PetSmart is a smaller pet supply store compared to most, but it offers friendly and knowledgeable staff who are great at resolving online order issues. Customers appreciate the helpfulness of the staff and the nice selection of well-cared-for fish. However, the fish selection can be limited, with some items out of stock. It is mentioned that the store restocks on Fridays, making it the best time to visit for a variety of fish. Overall, PetSmart provides good service and care for pets.
