Black Neon Tetra
Black Neon Tetra
Black Neon Tetra (Hyphessobrycon herbertaxelrodi) is one of the most distinctive and recognizable tetras — two bold parallel horizontal stripes, vivid white above and deep black below, run the full length of the body. The vivid red upper eye completes a striking three-color combination. Named for Herbert Axelrod, the prolific aquarium publisher and ichthyologist.
Feeding & Care Tip: Sera Vipan Tropical Flakes and Hikari Micro Pellets make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Bloodworms, Hikari Frozen or Freeze-Dried Baby Brine Shrimp, or Hikari Vibra Bites. Feed small amounts 2–3 times daily.
Native to the Mato Grosso region of Brazil — upper Paraguay and Araguaia drainages. More adaptable to varied water conditions than many small tetras. A feral population has established in the Rio Paraíba do Sul from aquarium releases.
Keep in groups of at least 8. The bold black-and-white stripes create maximum visual impact in numbers. One of the hardier small tetras.
An excellent and distinctive beginner tetra — the bold stripes and red eye make it immediately recognizable, and the hardiness suits a wide range of setups.
