Aquarium banana plants look best in the foreground. The thick green tubers resemble the banana fruit that we eat (hence the name).

How To Buy Healthy Aquatic Banana Plants

When you buy an aquarium banana plant, the leaves should be green and healthy-looking. These plants have solid green leaves. There should be no tears or holes in the leaves. The leaves can range from light green to dark green.
You can trim damaged leaves. But, if the freshwater banana plant looks like it won’t have many leaves left after trimming the damaged leaves then you should not buy it.

Also, when buying an aquarium banana plant, check the tubers. Tubers are the thick oval tubes underneath the stem that look like mini bananas. The tubers store the plant’s nutrients. The roots of the plants grow from the tubers. So, there should be tubers and these tubers should look healthy, thick, and green. Plants should not have algae growing on the leaves or other parts of the plant.

How To Plant Aquarium Banana Plant

There are two main ways to plant an aquarium banana plant. It all depends on whether the banana plant sinks or floats in the fish tank and the water flow of the aquarium.

In aquariums with calm water, it’s best to let the freshwater banana plant float above the substrate. This way, the banana plant can grow roots via the stem above the tubers. After a while, the roots grow down and take hold within the substrate.

In fish tanks that have a strong current, be sure that the tubers of the aquarium banana plant are not buried more than a 1/4 of an inch beneath the substrate.

How To Care For An Aquarium Banana Plant

Aquarium banana plants are easy to care for and are very hardy. These plants can thrive in varying tank sizes but aim for a 10 gallon tank minimum.

The aquarium banana plant is a foreground plant, so its best to root it in the substrate. Generally, aquatic banana plants do well at pH levels between 6.0 to 7.5, and the water temperature should be between 70 – 82 Degrees Fahrenheit.

As for lighting, moderate exposure to standard community tank lighting is enough for healthy growth. Aquarium banana plants usually grow a new leaf once every few weeks. They also produce new runners and roots over time.
