I know I am not alone in the fact that I love to look at fish. Even IRL I could spend an entire day in the aquarium and be content with that. This is NOT to replace the Stardew Aquarium. I love and highly recommend it! Though it doesn't show a lot of my favorite fish so I often find myself building my own aquariums on my farm, that's where this mod comes in! Themed rooms based on fish location will be released as well after Cedarbrook Village is live.
I also suggest using the Fish Tank Kit mod and its dependences as these fish tanks will fit the best but any fish tanks will still work!
