Starting a planted aquarium is quite a challenging but rewarding hobby. Since not everyone is in the mood to invest in the complete setup that high-intensity plants need, there are actually some types of aquarium plants that don’t need light.
However, with so many choices of aquatic flora and fauna, how to choose the ones that are best for you? Keep reading to find out more about the most wonderful tall low-light aquarium plants.
How Much Light Do Low Light Aquatic Plants Require?
Many aquarium hobbyists believe that bright light is necessary to make aquarium plants thrive. Although quality and brightness of the light are important, the balance between CO2 levels, nutrients, water quality, compatibility, and smart planting play a much more important role. These are the factors that make the difference between a healthy and a dying plant (in just a few days).
Keep in mind that plants need light to perform photosynthesis, without it the plant unfortunately dies. Compared to others, tall low-light aquarium plants are much more durable and have the ability to keep algae growth to a minimum. That is why they are ideal for beginners.
What does low light mean? It refers to a light source that gives less than 1.5 watts per gallon. How much light do low-light aquatic plants need depends on the species of plant you are growing. However, it is usually 10-12 hours of light a day.
The Best Low Light Aquarium Plants
These are our tall favorites that can adorn your aquarium as well.

Hornwort is a unique and beautiful aquarium plant that can be found in most parts of the world. It is a light green shrub-looking plant that has no real roots which means it doesn’t require a solid substrate.

Cryptocoryne Wendtii with its height up to 18 inches is one of the best-selling tall low-light aquarium plants. It quickly became quite popular due to its hardiness and easy maintenance and is therefore suitable even for beginners.

Since it usually grows up to 14 inches and more, Java Fern is an excellent mid-level or tall-level plant for low-light tanks. Java Ferns are easily recognizable by their specific leaf structure. In addition, it is also known as one of the hardest low-light aquatic plants.
