Diet: Algae, biofilm, spirulina wafers, blanched vegetables, and occasional frozen foods like brine shrimp or daphnia.
Feeding Frequency: 1–2 times daily in small amounts.
Tip: Ensure availability of natural algae growth or supplement with spirulina-based foods.
🛠️ Tank Maintenance
Tank Size: Minimum 50 liters (12 gallons) for a small group
Filtration: Moderate to strong flow with efficient biological filtration
Substrate: Fine sand or smooth gravel
Decor: Rounded stones, driftwood, and well-established planted areas for grazing
Lighting: Medium to bright lighting to promote algae growth
Water Change: 25–30% weekly with clean, oxygenated water
👥 Social Behavior
