YOUR TRUSTED AQUARIUM EXPERTS SINCE 1969

Who We Are

Elmer’s Aquarium was founded by Elmer Knabe and his wife Catharine in 1969. Over the years the store expanded several times into four adjacent store-rooms and basement, which is now the warehouse for Elmer’s Aquarium, where we store large tanks and stands.

Elmer’s Aquarium is still family owned and operated. While Elmer Knabe passed away in 1995, his son Gary, and his daughter Karen, who have been involved in the business since its beginnings, still operate the store to this very day! 

We have always specialized in offering a large selection of healthy tropical fish. Today we have one of the longest established businesses in the Monroeville area. Our years of expertise, unparalleled selection, and exceptional customer service have made us the trusted “local fish store” of many throughout the greater Pittsburgh area.
