🐟 Black Lyre Tail Molly Care Tips
✅ Tank Requirements
• Tank Size: 60 litres for a small group to ensure they have plenty of room to swim.
• Group Size: 3 or more; they are social fish and appreciate the company of their own kind.
• Substrate: Fine gravel or sand is ideal for their bottom-scavenging behaviour.
• Filtration: Reliable filtration is essential, though they prefer moderate flow rather than a strong current.
🌡️ Water Parameters
• Temperature: 22–28°C (72–82°F)
• pH: 7.0–8.5 (they prefer slightly alkaline, hard water)
• Hardness: 10–25 dGH
• TDS: 200–400 ppm
🍽️ Diet
• Omnivorous: Feed a balanced diet of high-quality flakes, micro-pellets, and frozen brine shrimp or bloodworms.
• Supplement with vegetable matter (such as spirulina or blanched zucchini) to maintain optimal digestion and health.
🧼 Tank Maintenance
• Perform weekly water changes (10–15%) using dechlorinated, temperature-matched water.
• Ensure your filter media is cleaned monthly in old tank water to keep beneficial bacteria colonies thriving.
🤝 Tank Mates
• Peaceful; best kept with other community fish such as platies, swordtails, tetras, and corydoras.
• Avoid aggressive fin-nippers that may target their beautiful, delicate lyre tails.
🍀 Colour & Health Enhancement
• Lighting: Moderate lighting helps highlight their deep, glossy black colouration against green plants.
• Diet: A mineral-rich, varied diet supports healthy growth and vibrant colour:
- High-quality colour-enhancing flake food
- Occasional live or frozen protein foods for optimal growth
- Calcium-rich supplements to support strong fin development
