  • Arrange them to form a natural-looking environment, perfect for hiding places.

4. Plant the Aquatic Flora

  • Gently place your aquatic plants into the substrate, burying their roots slightly.
  • Ensure each plant is positioned well, allowing them room to grow.

5. Add Water

  • Slowly fill the jar with dechlorinated water, being careful not to disturb the substrate or plants.
  • Use a cup or pitcher to pour in water gently.

6. Introduce Aquatic Life

  • After waiting a day for the water to stabilize, add your shrimp or small fish.
  • Monitor them for signs of stress during acclimation.

7. Maintenance

  • Check water levels and quality regularly.
  • Change 10-15% of the water weekly and replace with dechlorinated water.
