A minimum 100L aquarium suits Costae Tetra. Match décor to natural behaviour — plants, rockwork, or open swimming room as needed.
Keep pH 6–7.5 and 23–27°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Costae Tetra is omnivore — flake, frozen. Feed a varied diet appropriate for freshwater fish — quality flakes, pellets, or frozen foods sized to the mouth.
Costae Tetra is generally peaceful, active shoaler. Observe during feeding and at lights-out for true temperament.
Pair with similarly sized peaceful, active shoaler tankmates in freshwater fish. Avoid fin-nippers or species that outgrow this fish.
