Flameback Bleeding Heart Tetra (Hyphessobrycon pyrrhonotus)

The Flameback Bleeding Heart Tetra (Hyphessobrycon pyrrhonotus) distinguishes itself from other community tetras through a vivid crimson band that extends directly across the dorsal surface, creating a consistent visual anchor in established aquariums.

Native to the middle Rio Negro basin in Brazil, this species originally populates soft, acidic blackwater creeks and river shallows. In their natural habitat, they organize into large shoals, so maintaining a minimum group of five individuals is necessary to replicate their social behavior and prevent stress-driven hiding. Because they reach a medium to large size for the tetra family, they require spacious layouts with ample open swimming corridors.

For optimal housing, stock this species in a medium to large planted aquarium that pairs aquatic vegetation with submerged driftwood or leaf litter. The deep red iridescence along their back intensifies as the fish mature, making them a reliable centerpiece for densely planted or softly lit setups. Matching their native blackwater conditions with slightly acidic water parameters and gentle filtration supports natural osmotic function and sustained body coloring.

Selecting this variety over the common Bleeding Heart Tetra provides a more defined dorsal highlight and stronger shoaling discipline. Maintaining a cohesive group encourages synchronized daytime activity, predictable foraging patterns, and vibrant display states that persist through routine cleaning and water exchanges.
