Many of the tropical fish kept in freshwater aquariums are originally from the rainforest. Fish like angelfish, neon tetras, discus, and common algae-eating catfish come from the tropical forests of South America, while danios, gouramis, Siamese fighting fish (or Betta), and the clown loach are from Asia.
