J&M Tropical Fish was a pet store in south Philadelphia.
Adrian worked there with a woman called Gloria. Adrian worked here before her relationship with Rocky Balboa. She gave up the job after Rocky's first fight with Apollo, but decided to work there part time in the plot of Rocky II. She also worked in this shop during Rocky V, after the Balboa family moved back to their old Philadelphian neighbourhood.
Butkus lived here for a short while before Adrian brought him home as a pet for Rocky.
This is one of the places that Rocky and Paulie Pennino visits on the anniversary of Adrian's death, along with other significant places in and around Philadelphia.
