Tropical Friends Aquarium Store is owned by Brian Lewis, principal of Pearl Bailey High School.

In "Portrait of Francine's Genitals", Steve attempts to aid Klaus who is constantly plagued by a dirty bowl, which is significantly agitated by Roger's baseball persona "Rusty" spitting in it. Steve goes to the store to buy a filter, but considers the recommendations of Lewis for a stronger one. Steve confesses to being surprised to see his principal running such a shop. Lewis notes that his store regulars are equally surprised that he is a school principal.

When Hayley turns herself into a fish in order to keep Klaus from being deported by posing as a married couple in "One Fish, Two Fish", they go shopping for a new aquarium.
