Step-by-Step Instructions

With the following simple steps, you and your family can create a vibrant DIY aquarium jar.

Prepare the Jar

Before starting your DIY aquarium jar, it is important to guarantee that the jar is clean and free of any dirt or debris. The debris or dirt within the jar could potentially make your project less attractive.

Consider using gentle dish soap to cleanse the jar, ensuring that any soap residue is thoroughly removed with warm water. Beginning with a clean jar will result in a stunning and long-lasting aquarium.

Add Some Small Rocks

After cleaning the jar, ensure it is completely dry before continuing. Next, incorporate a layer of small rocks or gravel into the base to provide support for the artificial plants and toy fish that will be added later.

For optimal visibility of your toy fish, we suggest opting for light-coloured gravel. The size and colour of the gravel can be tailored to your personal preference and the overall design scheme of your aquarium jar.

Before adding them to the jar, it is important to ensure that the rocks or gravel used are free of dust or debris. This measure will guarantee the water in the jar stays clear. By sticking to these precautions, you can establish an aesthetically pleasing project for your home.

Add Your Artificial Aquatic Plants

Enhancing the natural appearance of your DIY aquarium jar can be achieved by incorporating artificial aquatic plants. You can easily purchase these from pet stores or online. Personal preference and jar size can determine the selection of plants, which come in different sizes and shapes.

To create a visually appealing appearance in your DIY aquarium jar, it is vital to arrange the artificial plants in a natural manner. Clutter or mess should be avoided. The use of tweezers can assist in the delicate placement of the plants into the gravel, guaranteeing they stay secure despite water disturbances.

Arrange the larger plants towards the rear of the jar and the smaller ones near the front to provide depth and enhance the spaciousness of the jar. Introduce various types of plants to create a captivating underwater habitat.

Certain plants can be positioned in the gravel, whilst others can be affixed to rocks or driftwood using fishing lines or plant glue.

Add Your Toy Fish or Octopus

Once you have adorned your jar with artificial aquatic plants, it is crucial to carefully choose the appropriate toy fish or octopus. Consider the dimensions of your jar and the area in which your toy creatures can move about.

For smaller jars, select small toy fish like guppies or neon tetras as they require less space to move. For larger jars, choose bigger toy fish like goldfish or bettas.

Fill with Water

Once you have arranged the artificial plants and included the toy fish, it’s time to fill the container with fresh water. It’s advisable to use a funnel to prevent any spillage or splashing on your creation or work surface.

Gradually add water to the jar, leaving some room at the top for ventilation. Be mindful not to overfill the jar as this will result in water overflowing when you attach the lid. Once you have filled the jar with water, give it a gentle swirl to distribute the gravel and adjust any plants or toys that may have shifted.

This will also help to release any air bubbles that may have formed in the water. After swirling, let the jar sit for a few minutes to allow the water to settle and any air bubbles to escape.

Close the Jar

When the water has settled and you are satisfied with the arrangement of your fish and plants, it’s time to place the lid on the jar. Make sure that the lid is secure and tight to prevent any accidental spills. And that’s it! You now have a beautiful aquarium jar to admire. Take a moment to appreciate your creation and the effort you put into it.

To showcase your DIY aquarium, position it in a brightly well-lit area within your home, avoiding exposure to direct sunlight. An ideal location could be near a window that receives indirect sunlight, highlighting the jar’s natural aesthetic appeal. Additionally, increase its appeal by including LED lights, producing a captivating and enchanting ambiance.
