Care notes

A minimum 200-liter tank is recommended for a group. Ideal temperature is 24–28°C, pH 5.5–7.0, GH 2–8. Fine sand substrate, roots, and catappa leaves create a favorable environment. Diet is omnivorous: small pellets, brine shrimp, bloodworms, and vegetables. It is compatible with most peaceful medium-sized fish. Avoid aggressive species. Regular 20% weekly water changes are necessary. Breeding is facilitated by soft, acidic water with a bonded pair.
