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.

  • 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.
