Hyphessobrycon amapaensis, commonly known as the Amapá Tetra, is a striking fish species endemic to Brazil. Let’s dive into some interesting details about this beautiful tetra:

• Etymology:

  • The genus name, Hyphessobrycon, combines the Ancient Greek word “υπελάσσων” (hyphesson), meaning “of lesser stature,” used as a prefix, with the generic name Brycon.
  • The specific epithet, amapaensis, refers to the state of Amapá in northeastern Brazil.

• Distribution:

  • This tetra is known only from a small area within the rio Preto and rio Maraca drainages in Amapá state, northeastern Brazil.

• Habitat:

  • Hyphessobrycon amapaensis inhabits small streams flowing through savanna grassland.
  • The water is clear and light brown-colored, with substrates of sand and gravel.

• Appearance:

  • Mature specimens exhibit a striking red lateral stripe.
  • Unlike its close relative, H. heterohabdus, only the red lateral stripe tends to extend to the caudal peduncle.

• Aquarium Care:

  • A tank with base dimensions of 60 cm × 30 cm or equivalent is suitable.
  • Consider a setup with a sandy substrate, driftwood roots, and branches.
  • Dried leaf litter enhances the natural feel and provides additional cover for the fish.
  • Water conditions:
    • Temperature: 23°C to 28°C
    • pH: 5.0 to 7.0
    • Hardness: 18 to 143 ppm
    • Conductivity: 5 to 15 μS

• Diet:

  • Likely omnivorous, feeding on small invertebrates, crustacea, filamentous algae, and fallen fruit in nature.
  • In captivity, offer a varied menu including live and frozen foods like chironomid larvae (bloodworm), mosquito larvae, Daphnia, and Moina
