Black Line Costae Tetra (Hyphessobrycon costae) – A Bold and Beautiful Addition to Your Aquarium

The Black Line Costae Tetra (Hyphessobrycon costae) is an elegant and vibrant species known for its striking black line running along its body, contrasted by a beautiful golden or yellowish sheen. This unique coloration, combined with its streamlined body, makes it a standout species in any freshwater aquarium. With its peaceful temperament and active schooling nature, the Black Line Costae Tetra is an excellent choice for both beginner and experienced aquarists looking to add color and liveliness to their community tanks.

Native to the clear waters of South America, particularly the Amazon basin, the Black Line Costae Tetra thrives in well-planted aquariums with soft water and gentle filtration. Its striking appearance and easygoing nature make it a perfect addition to any peaceful community tank.

Key Features & Care Guidelines:

  • Distinctive Coloration: A shimmering golden or yellow body adorned with a bold black line running from head to tail, making it a striking contrast in any tank.

  • Behavior: Peaceful and active schooling fish, best kept in groups of 6 or more to promote natural schooling behavior and reduce stress.

  • Tank Size: Minimum 20 gallons recommended for a small school, but larger tanks are ideal for a dynamic display.

  • Water Parameters: Prefers slightly acidic to neutral water with a pH between 6.0 and 7.5, and temperatures from 74°F to 80°F (23°C to 27°C).

  • Diet: Omnivorous; accepts flakes, micro pellets, and live or frozen foods such as brine shrimp, bloodworms, and daphnia.

  • Tank Setup: Thrives in planted tanks with plenty of swimming space, hiding spots, and gentle water flow. Soft lighting will enhance its golden sheen and bold black line.

  • Experience Level: Hardy and adaptable, making it a great choice for both novice and experienced aquarists.

The Black Line Costae Tetra (Hyphessobrycon costae) is the perfect fish to add a touch of elegance, color, and activity to your aquarium. Whether schooling in a group or exploring the tank on its own, this beautiful species will be a highlight in any aquatic environment.
