Preparation

  • Clean your jar thoroughly and remove any labels.
  • Allow it to dry completely before starting.

Assembly

  • Pour a layer of small pebbles or aquarium gravel to the bottom of your jar for drainage.
  • If using activated charcoal, sprinkle a thin layer on top of the gravel.
  • Layer potting soil over the charcoal (if used) about an inch deep and gently press it down to make a smooth surface.
  • Using tweezers, place your aquatic plants into the soil ensuring that roots are buried but leaves should remain above the soil.
  • Position decorative items around the plants to create a visually appealing scene.
  • Slowly pour water into the jar, being careful not to disturb the soil or plants.
  • If your jar has a lid, place it on top; otherwise, leave it open for an open terrarium effect.
  • Place your mini aquarium in a well-lit but indirect sunlight area.

Notes

Experiment with different types of aquatic plants or add more color with flowering varieties. Ensure any fish included are compatible with the jar size.
