The red tail black neon variatus are vibrant and active. They add a lot of movement to the tank. Easy to maintain and get along well with other peaceful fish. The color stands out even in a mixed community.

Great fish with bold colors and interesting fin movements. They jump occasionally, so a tank with a lid is recommended. Very active and lively in a 10-gallon setup.
