So I was wondering what zoo/aquarium has a good collection of freshwater fish. Ofc Zoo Berlin and Shedd Aquarium come to mind, but are there other institutions that stick out in this regard ? And do they have species that are rarely seen ?
The Tennessee Aquarium is known for their freshwater fish collection. They have added saltwater fish over time, but they still have a great collection of freshwater fish.
New England Aquarium had a very extensive freshwater collection at one time that while mostly limited geographically to species from either Massachusetts or the Rio Negro, was extremely diverse.
Have not been back in years though, not sure where the collection is at now.
