The emperor tetra (Nematobrycon palmeri) is a freshwater fish that belongs to the Characidae family. It is native to the San Juan and Atrato river basins in Colombia
Like many tetra fish, emperor tetras have long captured the interest of aquarists and first-time fish owners due to the fish’s stunning iridescent scales, peaceful nature, and ease of care.
While emperor tetras will bring a calming and colorful presence to your tank, they are schooling fish and will need to be kept in a group of at least six.
