How to Convert a Flower Vase Into a Fish Tank

The next time you win a fish at the county fair or your child begs for a pet, don̵7;t waste your money on an elaborate fish bowl or tank. Instead, use a glass vase collecting dust in the closet to house a smaller goldfish or betta. There are several considerations to keep in mind when housing a fish in any glass bowl, including a vase, that contains no filtration system. With a little extra work, almost any ordinary glass vase makes a suitable home for your new pet.

Instructions

    • 1

      Clean the vase with mild dish soap and water. Scrub the inside of the vase with a baby bottle cleaner and rinse it well with warm water. Dry the vase with a soft cloth to prevent streaks and water marks. Mild soap contains no dyes or perfumes.

    • 2

      Pour a 2- to 3-inch layer of aquarium pebbles or rocks. Rinse the rocks with distilled water to remove any impurities before pouring them into the vase.

    • 3

      Place two to three aquarium plants into the vase, depending on the amount of available space. Secure the plants by gently pushing them into the aquarium pebbles or rocks. Do not add more plants than the vase can accommodate to prevent overcrowding the space.

    • 4

      Fill the vase half-full with water that is between 60 and 70 degrees Fahrenheit. Allow the water to sit for at least 24 hours before introducing the fish.

    • 5

      Pour the fish, and the water it is currently living in, into the glass vase. Do not allow the vase to become more than three-quarters full to ensure the fish does not attempt to jump out. Avoid removing the fish from its original water and dropping it into the vase to prevent shocking it.

      Set the vase fish tank on a sturdy structure in a well-lit area.
