Floating Aquarium Plants Care, Types and Growing

Floating aquarium plants are a type of aquatic plants that naturally float on the surface of the water in an aquarium. They have specialized adaptations that allow them to thrive in this unique environment.

Floating aquarium plants are a fantastic addition to any aquatic environment. Not only do they enhance the beauty of the tank, but they also offer numerous benefits such as providing shade, absorbing excess nutrients, and creating natural hiding spots for fish. In this comprehensive guide, we will explore the care requirements, benefits, and top choices of floating aquarium plants, answering key questions to help both beginners and experienced aquarists make informed decisions.

Floating Aquarium Plant Types

Aquatic plants can be categorized into different types based on their growth habits and requirements. Here are several types of aquatic plants commonly found in aquariums:

1. Stem Plants: These plants have long, flexible stems with leaves growing along them. Examples include Rotala, Ludwigia, and Cabomba. Stem plants are often used for background or midground plantings in aquariums.

2. Rosette Plants: Rosette plants form a circular arrangement of leaves at the base of the plant. They usually have a rosette-like appearance and can vary in size. Examples include Amazon sword (Echinodorus species), Cryptocoryne species, and Rosette water lily (Nymphaea species).

3. Carpeting Plants: These low-growing plants spread across the substrate, creating a carpet-like effect. They are commonly used in aquascaping to create a lush foreground. Examples include Dwarf baby tears (Hemianthus callitrichoides), Monte Carlo (Micranthemum tweediei), and Glossostigma (Glossostigma elatinoides).

4. Mosses: Aquatic mosses are popular for their ability to attach to various surfaces and create a natural and textured appearance. Examples include Java moss (Taxiphyllum barbieri), Christmas moss (Vesicularia montagnei), and Flame moss (Taxiphyllum sp. “Flame”).

5. Floating Plants: Floating plants naturally float on the water’s surface and provide various benefits to the aquarium ecosystem. They can provide shade, absorb excess nutrients, and offer refuge for fish and fry. Examples include Duckweed (Lemna minor), Water lettuce (Pistia stratiotes), and Salvinia species.

6. Bulb Plants: These plants grow from bulbs or rhizomes and can add a unique visual appeal to the aquarium. Examples include Aponogeton species and Madagascar lace plant (Aponogeton madagascariensis).

7. Anubias and Java Fern: These plants are often attached to hardscape materials like rocks or driftwood rather than being planted in the substrate. Anubias and Java ferns are known for their hardiness and adaptability to various water conditions.

8. Floating Ferns: Floating ferns have delicate, feathery leaves and float on the water’s surface. Examples include Water sprite (Ceratopteris thalictroides) and Giant Salvinia (Salvinia molesta).

9. Oxygenating Plants: Oxygenating plants, also known as submerged plants, release oxygen during photosynthesis and help maintain good water quality. Examples include Hornwort (Ceratophyllum demersum), Vallisneria species, and Egeria densa (formerly Elodea densa).

These are just a few examples of the many types of aquatic plants available for aquariums. Each type has its own unique characteristics and care requirements, so it’s essential to research specific plants before adding them to your aquarium.

How to Grow Floating Aquarium Plants

  • To grow floating aquarium plants, start by choosing a well-drained aquarium with a gravel or sand substrate.
  • Fill the aquarium with fresh water and add the plants of your choice.
  • Once the plants are established, add a few drops of fish fertilizer every week and change the water once a month.

If your plants grow too densely, trim them with a sharp knife.

How to Keep Floating Aquarium Plants from Covering Entire Aquarium Surface

If your floating plants start to cover the entire aquarium surface, it’s time to take action.

To keep floating plants from covering the tank, add weight to the bottom of the aquarium. It will help keep the plants down and can also be used as a floating plant stand.

How to Supply Nutrients to Floating Aquarium Plants

There are several ways to supply nutrients to your floating aquarium plants. You can either use a liquid fertilizer or a pelletized fertilizer.

Liquid fertilizers can be used in either regular or algae-free water. Make sure to follow the instructions on the container.

Pelletized fertilizers come in various forms, including granules, liquids, and pellets. You add them to the water and watch them dissolve.

How to Set Up Aquarium for Live Floating Plants

  • The first step in setting up your aquarium for floating plants is to choose the plants.
  • Once you have selected your plants, it is time to fill the aquarium with water.
  • Next, add the plants to the aquarium. Make sure the plants are floating upright, and the roots are submerged.
  • Finally, add water to the aquarium to the level corresponding to the plants’ size. Also, add some live rocks or gravel to give the plants something to attach to.

How to Care for Floating Aquarium Plants

To care for your floating aquarium plants, perform a water change every two weeks to ensure the plants receive the correct amount of water and nutrients. Remember to add a water-soluble fertilizer to the aquarium every week or so to help the plants grow and thrive.

Which floating aquarium plants provide the most shade for fish?

Water lettuce and Salvinia are renowned for their ability to provide ample shade. Their dense foliage effectively reduces light penetration, creating shaded areas in the aquarium that help alleviate stress for fish and prevent algae growth.

What are the benefits of using floating aquarium plants in a planted tank?

Floating plants offer several benefits to planted tanks. They absorb excess nutrients, preventing their buildup and reducing the risk of algae blooms. Additionally, they provide a natural habitat and hiding places for fish and fry while enhancing the overall aesthetic appeal of the tank.

Can floating aquarium plants help control algae growth in the aquarium?

Yes, floating plants play a vital role in controlling algae growth. By outcompeting algae for nutrients and reducing light penetration, they help maintain a healthy balance in the tank. Additionally, their roots provide a surface for beneficial microorganisms to colonize, further aiding in algae control.

Which floating aquarium plants are suitable for low-light conditions?

If your tank has low-light conditions, Java fern and floating ferns such as Salvinia natans are great choices. These plants can tolerate lower light levels while still providing the benefits associated with floating plants.

What are the ideal water parameters for maintaining healthy floating aquarium plants?

Floating plants generally adapt well to a range of water conditions. However, most prefer temperatures between 72-82°F (22-28°C) and a pH range of 6.5-7.5. Regular water changes and adequate nutrient levels are crucial for their overall health.

What are some tips for preventing floating aquarium plants from overcrowding the tank?

To prevent floating plants from overtaking the tank, regularly thin out the excess growth and remove any plants that cover too much of the water surface. This will ensure proper gas exchange and allow sufficient light to reach other plants or aquatic animals in the tank.


Floating aquarium plants offer both aesthetic appeal and numerous benefits to freshwater tanks. Whether you’re a beginner or an experienced aquarist, incorporating floating plants like duckweed, water lettuce, and Amazon frogbit can enhance the health and beauty of your aquarium. Remember to consider the specific needs of your tank and the preferences of your fish when selecting and caring for floating plants. With proper care, these plants will thrive and contribute to a thriving aquatic ecosystem.
