The Buenos Aires Tetra (Hyphessobrycon anisitsi) is a robust and lively freshwater fish, easily recognized by its silver body with a hint of gold and a distinctive red-tipped tail fin. Native to the rivers and streams of Argentina, Brazil, and Paraguay, these tetras are hardy and adaptable, thriving in a range of water conditions. They are active swimmers and should be kept in schools to minimize aggression and enhance their vibrant colors, making them an engaging addition to community aquariums.
