Keep pH 7–8.5 and 22–28°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Black Devil Snail is omnivore — algae, detritus, sinking foods. Feed a varied diet appropriate for invertebrates — quality flakes, pellets, or frozen foods sized to the mouth.
Black Devil Snail is generally peaceful, active grazer. Observe during feeding and at lights-out for true temperament.
