Everything you need to keep Slender Rasbora healthy in a South African setup.
A minimum 60L aquarium suits Slender Rasbora. Match décor to natural behaviour — plants, rockwork, or open swimming room as needed.
Keep pH 5.5–7 and 23–27°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.

Slender Rasbora is generally peaceful shoaler. Observe during feeding and at lights-out for true temperament.
