Hi, I want to change the look of my aquarium in the future because I got it as a gift when I was 6-7 years old, and it looks very childish. I want to make it look a lot more natural, like the Amazon. To do this, I want to change my substrate and move my goldfish to a different tank. Are Angel Fish, Zebra Danio, Bristlenose Pleco, Corydoras, and Neon Tetras a good stocking choice for the aquarium? Any tips to design an aquarium like the Amazon?
NOTE: My aquarium is 60 liters about 15 gallons.
