Overview
The flameback bleeding heart tetra is a peaceful schooling tetra for a warm blackwater tank. It is a fish for a keeper who has some experience.
Did you know
The flameback bleeding heart tetra's color depends on its water. In hard, bright water it looks ordinary, but in soft, dark water the back truly ignites. Wild fish from the Rio Negro glow like coals.
Caring for the flameback bleeding heart tetra
Keep six or more flameback bleeding heart tetras, in a tank of at least 20 gal (75 L). Give them stained water, leaf litter and shade.
They want warmth and acidity, at 75 to 82°F (24 to 28°C) and a pH of 5.0 to 6.8. The darker and softer the water, the better. Feed flake, granules and meaty frozen foods.
Like other bleeding hearts, this tetra is peaceful but substantial, so keep it with calm, midsized company. Breeding it is hard.
Good to know
Hyphessobrycon pyrrhonotus was described in 1993, and its name means flame-backed. It is one of three bleeding heart tetras in the hobby. It pairs the classic bleeding-heart shoulder spot with a band of glowing red along the upper body, which neither of the other two carries.
In the wild
The flameback bleeding heart tetra comes from the Rio Negro basin in Brazil, true blackwater country.
