5 Best Floating Aquarium Plants

Do you have a fish tank or fishpond in your compound that you would like to transform?

You can rework the look of your fish pond by introducing floating aquarium plants. The plants give your fish pond or Aquarium an entirely fresh look.

They are the best if you are considering giving your fish pond and the surrounding environs an aesthetic appeal.

For you to choose the best plants for your Aquarium, you first need to assess if the fish are better suited for that plant. Also, the size of your Aquarium plays a significant role; if your fishpond is less than 40 liters, then you should opt for small plants.

Below are five of the top floating aquarium plants for novices. But first, how does a floating aquarium plant add value to your fishpond.

What Are The Benefits of Aquarium Plants?

The good thing about these aquarium plants is that they provide your fish with more oxygen as they go through photosynthesis.

The plant’s branches and leaves provide the fish with shade, and for the small fish and tadpole, it acts as a hiding place.

Fish that loves eating live vegetation can also snack on these floating plants. The aquarium plants absorb fish waste and nitrogen components in the water, making the water clean and easing the filter’s workload.

They also prevent the growth of other species, such as harmful bacteria. Do not plant this freshwater plant in an open water body as it can get out of control and become a hazard.

1. Hornwort

Hornwort is also referred to as Coontail. It is a popular aquatic plant suitable for a fish tank or a fishpond. This is because it’s the easiest aquarium plant to grow and maintain. Fish keepers love hornwort because of its fluffy-like stems, which overgrow and absorb any excess nutrients in the water.

You will find it floating on the water, but when planted at the pond or aquarium base, it creates a bushy-like appearance under the water because of its long fluffy branches. Hornwort has pine-like leaves that are thin and rigid. Its bushy-like appearance provides the fish and shrimp with ample protection.

Origin

Hornwort can grow in various water conditions, making it ideal for newbies. Apart from Antarctica, this freshwater plant can grow anywhere else on the continent. Because of its fast growth rate, you only need a little of it. Hornwort prefers still waters as they contain loads of organic nutrients.

Where to buy

You can buy hornwort at Amazon, Life Aquaria, PetSmart, and Pond megastore

Maintenance

The advantage of a hornwort is that you can plant them in extreme weather conditions. Check on it regularly and prune it back to avoid overgrowth as it will block from getting to the other plant.

Its overgrowth will also limit gaseous exchange and nutrients available, which may cause your fish to die because of inadequate oxygen.

2. Red Root Floater

Maintenance

It is a tough plant, making it suitable for beginners. The primary requirement for growing Red root floater is light and enough surface area. However, do not expose the plant to too much light; instead, it’s best to use artificial lighting, which is easier to control.

Ensure that the water pH ranges between 6.5 to 7.5 and that carbon dioxide content is low. The water hardness should be between 0-30Dgh. The aquarium temperature should be maintained between 18 to 20 degrees Celsius.

Your plants need enough iron to maintain their red coloration, so if it’s not enough, you can supplement by adding fertilizers. However, avoid unwarranted use of chemicals as they may harm your plants and fish.

Prune out excess red rood floater as it may lead to overgrowth covering the Aquarium’s entire surface. This will affect other plants’ growth, nutrients, and gaseous exchange and may lead to the fish and plants’ demise. Start trimming the leaves under the water.

You can use small pots to plant Cabomba at the base of the Aquarium. Trim regularly to prevent overgrowth. Also, you can replant cuttings obtained from mature plants.

The plant requires adequate light to grow, so if you are using an artificial lighting system, ensure that it at least 3 watts per gallon. Although Cabomba does not require Carbon dioxide, its inadequacy can cause the shedding of leaves.
