Not as Simple as It Looks

If you have never owned a fish tank, it may be tempting to try to start with a nano tank.

Keep in mind that a smaller tank will likely get dirty faster, as there is not as much water to help maintain a proper pH level. For that reason, regular water changes are crucial to the health of your fish and to maintain the beauty of your aquarium design.

Because it’s a small living space, it’s also important to choose fish that are likely to be compatible and to include components such as gravel and plants.
