How to Grow Pothos in An Aquarium in Three Easy Steps?

Aquarium Plants

Growing pothos in an aquarium is similar to propagating pothos in water. All you have to do is to start with a healthy cutting to avoid infecting your aquarium water and fish. I cut my pothos at an angle and used a stem about a foot to a foot and a half long. I find that the longer you go, the better results you will get. Then you will need to remove any leaves at the bottom of the cutting.

After you prepare your clean and healthy cutting, you can submerge a segment of the stem underwater. Then, anchor the plants so only their roots and part of the stem are in the water but not the leaves.

Generally, roots will sprout out of there in a matter of a few days if you provide sufficient light. This plant will grow new leaves rapidly if you give it enough light. Also, don’t forget to cut the roots regularly to keep the aquarium looking good because pothos roots will grow at high speed in aquariums.

What Are the Benefits of Growing Pothos Underwater?

There are many benefits to growing pothos in an aquarium, but one of the most notable is that it can help reduce the level of nitrates in the water. This is because pothos removes nitrogen from the water, which helps keep your fish healthy and reduces the amount of algae growth in the aquarium.

So if you grow pothos in your aquarium, they will make it aesthetically pleasing by making the water clean and transparent. But more importantly, pothos will reduce your work to maintain your aquarium because you will change the water less frequently.

Another benefit of growing pothos in an aquarium is that it absorbs carbon dioxide secreted by the fish and releases more oxygen into the water. This helps your fish stay healthy since they don’t need to overproduce their oxygen, which is harmful to aquarium fish.

In fact, too much carbon dioxide in the water can be unhealthy to fish, making the water more acidic and can cause them to become sick.

Growing pothos in an aquarium can also help combat algae growth. As mentioned above, pothos removes nitrogen from the water, inhibiting algae growth and keeping your aquarium clean and healthy.

Finally, pothos is a great option if you’re looking for an easy way to cover up your aquarium. But it would help if you considered growing many stems to fully cover your aquarium.

Wondering about the Best Time to grow Pothos? Here is the exact answer.

Is Pothos Safe for Aquarium Fish?

Pothos can be safely grown in any aquarium, from freshwater tanks to saltwater tanks. However, pothos is not very nutritious for fish and will need to be supplemented with other plants or food.

Additionally, the leaves of the plant can become covered in algae if you don’t keep them trimmed, so it’s essential to monitor the growth of the pothos in your aquarium. If you’re looking for more nutritious plants to help keep your fish healthy, try growing some Java moss or Anubias nana instead.

Finally, pothos can provide egg-spawning fish with places to lay their eggs and harbor them until they hatch.
