The distribution of the Buenos Aires Tetra is widespread in river systems across Brazil, Paraguay, Argentina, and Uruguay. While most available specimens in the aquarium trade are captive or commercially produced, this species remains popular. With its elongated silver body and orange fins, the Buenos Aires Tetra is a resilient fish. These tetras are natural shoaling fish and thrive in groups of at least 8 individuals, but more are recommended. It is particularly crucial to have multiple individuals of this species to prevent aggressive behavior towards other tankmates. As an adult, the Buenos Aires Tetra can grow to a size of approximately 2.5″.
