MORTALITY and LONGEVITY: The bright, neon, lateral stripe of cardinal tetras makes it difficult for predators to single out and attack an individual. Their schooling behavior also helps to protect individuals from predators.

Adults often perish due to starvation after spring floods when foraging habitats retract during the low water season. They are preyed upon by other fishes including piranha.

Cardinal Tetra live about one year in the wild average 5 years in captivity.

CONSERVATION: IUCN: Not evaluated.
