Description
The Redflank Bloodfin is a small, active schooling tetra known for its iridescent green-blue body and vibrant red coloration on its flanks and fins, especially prominent in males. They are generally peaceful but thrive in groups of six or more, which helps curb any potential fin-nipping behavior. This species adds a splash of color and activity to a well-maintained community aquarium.
