The Argentine Bloodfin Tetra typically measures about 5 to 6 centimeters in length and is known for its sleek, silvery body. Their bodies are mostly transparent silver, reflecting light beautifully, while their fins—especially the caudal, dorsal, and anal fins—display vivid red coloration. This striking contrast between the shimmering body and bright red fins makes them stand out elegantly in the aquarium.

Argentine Bloodfin Tetras are social fish and are usually best kept in groups to reduce aggression and encourage natural schooling behavior among individuals.
