Natural Habitat and Origin

In the wild, Neolebias trilineatus inhabits west and central africa; exact range is not well documented in aquarium sources, but the genus is native to slow-moving freshwater habitats in tropical africa. Understanding their natural environment helps us replicate optimal conditions in the home aquarium.

The natural habitat features specific water chemistry and environmental conditions that we carefully replicate in captive care for optimal health and longevity.

Aquarium Setup and Requirements

A minimum tank size of 60 litres is essential for housing Three-Lined African Tetra,. Larger aquariums provide more stable water chemistry and greater swimming space, both critical for long-term health.

A well-planted aquarium with open swimming areas suits this species perfectly. Use a dark substrate to enhance coloration, and include driftwood and leaf litter to create natural tannins and hiding places.

Invest in quality filtration capable of turning over the tank volume 4-6 times per hour, and perform regular 25-30% water changes weekly to maintain pristine conditions.

Expert Tip

Always keep Three-Lined African Tetra, in groups of 6+ individuals. Smaller groups cause stress, faded colors, and abnormal behavior. Larger schools create spectacular displays!

Water Parameters and Chemistry

Maintaining correct water parameters is crucial for the health of Three-Lined African Tetra,:

  • Temperature: 24-28C
  • pH Range: 5.5-7
  • Hardness: See species-specific requirements
  • Ammonia/Nitrite: 0 ppm (zero tolerance)
  • Nitrate: Below 20 ppm ideally

This species prefers soft, acidic water. Use RO water remineralized to appropriate GH/KH, add Indian almond leaves or alder cones for tannins, and avoid calcareous decorations that raise pH.

Invest in quality test kits and check parameters weekly. Stability is more important than hitting exact numbers - avoid sudden changes that stress fish.

Feeding and Nutrition

As a microcarnivore, Three-Lined African Tetra, requires a carefully balanced diet to maintain optimal health and coloration.

Offer a varied diet of small live and frozen foods such as daphnia, baby brine shrimp, mosquito larvae, and finely chopped bloodworms, supplemented with quality micro-pellets or crushed flakes.

Feed 1-2 times daily in small amounts. High-protein sinking pellets, frozen bloodworms, brine shrimp, and mysis form the foundation of a healthy carnivore diet. Avoid mammalian proteins which can cause digestive issues.

Remove uneaten food after 3-5 minutes to prevent water quality degradation. A single weekly fasting day can benefit digestion and overall health.

Behaviour and Temperament

The Three-Lined African Tetra, is classified as peaceful, though individual personality can vary with age, tank size, and stocking density.

This peaceful species thrives in community setups with similarly sized, non-aggressive tankmates. Calm demeanor and gentle nature make it ideal for planted aquariums.

Best kept in a mature, dimly lit aquarium with plenty of cover, fine plants, leaf litter, and very clean water. It is a shy, small species that may be outcompeted by larger or faster fish, so choose...

Compatible species include:

  • Other small peaceful African fish of similar size
  • Small peaceful nano fish

  • Large predatory fish
  • Aggressive cichlids
  • Fin-nipping species
