🐟 Corydoras trilineatus Care Tips

✅ Tank Requirements

• Tank Size: Minimum 60 litres for a small colony to allow for active foraging.
• Group Size: 6 or more; these are social fish that thrive in numbers.
• Substrate: Fine, smooth sand is essential to protect their sensitive barbels from damage.
• Filtration: Moderate flow with good oxygenation; keep the substrate clean to prevent infections.

🌡️ Water Parameters

• Temperature: 22–26°C (72–79°F)
• pH: 6.0–7.5
• Hardness: 2–15 dGH
• TDS: 100–250 ppm

🍽️ Diet

• Omnivorous: Feed high-quality sinking catfish pellets, granules, and frozen foods like bloodworm or daphnia.
• Supplement with occasional live foods to encourage natural foraging behaviour and vibrant colour.

🧼 Tank Maintenance

• Perform weekly water changes (10–15%) using dechlorinated, temperature-matched water.
• Maintain a clean substrate by vacuuming regularly, as these fish spend their lives sifting through the sand for morsels.

🤝 Tank Mates

• Extremely peaceful; best kept with other community fish like tetras, rasboras, and dwarf cichlids.
• Avoid large, aggressive, or predatory fish that may harass or swallow them.

🍀 Colour & Health Enhancement

• Lighting: Provide areas of shade with floating plants or driftwood to help them feel secure and show their best colour.
• Diet: A mineral-rich, varied diet supports healthy growth and vibrant colour:

• High-quality sinking sinking pellets
• Occasional frozen protein foods for growth
• Varied diet to boost natural immune health
