• Substrate: Fine sand or smooth gravel to mimic their natural environment.
• Environment:
  • Dense planting with fine-leaved plants like Java moss, Rotala, or Vallisneria.
  • Floating plants to diffuse lighting and create shaded areas.
  • Driftwood and rocks for added hiding spots and aesthetics.

Diet:

• Omnivorous:
  • High-quality micro-pellets or flakes as a staple.
  • Live or frozen foods like brine shrimp, daphnia, and micro worms.
  • Occasional vegetable-based foods like spirulina flakes.

Care Tips:

1. Keep in a well-planted aquarium to reduce stress and enhance their vibrant coloration.
2. Maintain stable water parameters with regular water changes.
3. Ensure the tank is peaceful to accommodate their shy nature.

Breeding:
