Tropical freshwater aquariums are most often stocked with fish, invertebrates, and plants native to the warm, lush waters of the tropics. This includes species from South America, Africa, and Southeast Asia that thrive in warm, soft, acidic water conditions. Vibrant tetras, angelfish, shrimp, and livebearers are some classic examples. Live aquarium plants like Amazon swords, Java fern, and moss help oxygenate the water and recreate the lush look of a tropical stream or river.
