  • pH: 6.0-8.0.
  • Hardness: 5-20 dGH.
• Filtration: Strong filtration is essential to keep the water clean and oxygenated due to their waste production.
• Substrate: Smooth substrate (sand or fine gravel) to prevent injuries to their fins.

Diet and Feeding

• Diet Type: Omnivorous.
• Feeding Schedule: Feed 2-3 times a day, providing only what they can eat in 2-3 minutes.

• Activity Level: Active swimmers, requiring plenty of space to move around.

Breeding

• Breeding Season: Generally occurs in warmer months (spring and summer).
• Spawning: Males may chase females to encourage spawning. Remove adults after spawning to protect the eggs.
• Eggs: Females can lay hundreds to thousands of eggs, which typically hatch in 3-5 days under ideal conditions.

Health and Care

• Regular Maintenance:
  • Change 10-15% of the water weekly to maintain water quality.
  • Regularly test for ammonia, nitrite, and nitrate levels.
• Common Diseases:
  • Ich (White Spot Disease): Treat with heat and salt or appropriate medications.
  • Fin Rot: Address water quality issues and use antibacterial treatments as needed.
  • Swim Bladder Disorder: Often caused by overfeeding; adjust diet and monitor water conditions.
