What is the main difference between a 20 Long and a 20 High gallon aquarium?

The primary difference lies in their dimensions. A 20 Long aquarium has a longer length but shorter height, making it wider and lower profile. In contrast, a 20 High aquarium is taller and has less length, offering a smaller footprint but greater depth.

Is there a difference in maintenance between the two?

Maintenance efforts can vary slightly. The 20 Long aquarium may require more substrate cleaning due to its larger bottom surface, while the 20 High might need more attention to water parameters since its depth can affect light penetration and circulation.
