2020 is an unforgettable year. Because of covid-19, everyone in the world must stay at home. Tropical fishs became our friends at the time.
Tropical fish are generally those fish found in aquatic tropical environments around the world. Fishkeepers often keep tropical fish in freshwater and saltwater aquariums. The term "tropical fish" is not a taxonomic group, but rather is a general term for fish found in such environments, particularly those kept in aquariums.
