Common name:Black Neon tetra, Calypso tetra
Scientific name:Hyphessobrycon herbertaxelrodi
Synonyms:Megalamphodus axelrodi (not valid)
Size:1.5-2" (4-5cm)
Origin:South America: Mato Grosso area of Brazil.
Tank setup:Planted tank, with open shoaling space.
Compatibility:A peaceful fish for a community tank with other similarly peaceful fish.
Temperature:23-27oC (73-81oF)
Water chemistry:Not critical, but soft and slightly acidic preferred.
Feeding:Omnivorous: Flake, granules/micro-pellets and small live or frozen foods.
Sexing:Males slimmer, females have a deeper body.
Breeding:An egg-scatterer which spawns fairly readily, in open water. Eggs take just over a day to hatch.
Comments: A hardy fish for the peaceful planted community aquarium. Adapts to a range of conditions, but soft, slightly tannin-stained water will bring out the best colours.
Despite the common name, this is not a colour form or variant of the common Neon tetra, but a completely separate species.
