14 Best Floating Plants for Your Aquarium

Anacharis (Egeria densa)

Anacharis is one of the most common and easiest to grow aquatic plants. It is recommended as a good choice for any beginner aquatic plant tanks. It grows quickly and can handle a variety of water temperatures, making it a good fit for different aquariums.

Duckweed (Lemna minor)

This is a very common plant that likes to hitch a ride on other aquatic plants. It only takes one cell to start reproducing and is VERY hard to eliminate once it is in your system. Best way to avoid it? Quarantine your aquatic plants and if it appears and you don't want it around, remove it before it gets out of control.

Java Moss (Vesicularia dubyana)

Although typically associated with cultivation on driftwood and rocks, java moss can float freely throughout your aquarium. Compared to other aquatic plants, java moss does not grow very quickly and can be planted if you desire. It does not grow very high, and often creates a mat covering substrate and décor items.

Hornwort (Ceratophyllum demersum)

Hornwort is another popular choice for its aesthetic and ease to cultivate. They can be planted, if desired, or allowed to float freely. It can grow very fast, so be ready to trim as necessary so it does not overwhelm your fish.

Amazon Frogbit (Limnobium laevigatum)

Think of Amazon Frogbit like aquatic clover. These plants form rosettes and with relatively short roots, do not compete for your fish's swimming space. They can provide considerable shade cover, so take care if you have other submerged plants. The deeper plants might not be able to get enough sunlight to survive.

Dwarf Water Lettuce (Pistia stratiotes)

"Dwarf" water lettuce and regular water lettuce are usually sold interchangeably and are not related to real lettuce. These plants get their name from their lettuce-like leaves and "head" shape.

Please bear in mind that water lettuce is an invasive species, so you may not be able to get it in your state. If you choose to keep it, NEVER allow it to reach natural water sources. It easily overwhelms native systems and is a pain to remove.

Water Sprite (Ceratopteris thalicotoides)

One of the most well-known aquatic plants is the water sprite, also known as water fern or Indian Fern. It is highly recommended for providing hiding space for smaller orshy fishand is very tolerant of beginners.

Cabomba (Cobomba caroliniana)

A wild weed, Cabomba, also commonly known as Carolina fanwort, can grow very quickly and provides bushy cover for shy fish. It can be planted or float freely, depending on your tank plan. It is a hardy floating plant and will do better than some more delicate aquarium plants.

Water Spangles (Salvinia minima)

Water spangles prefer still water compared to fast-moving surface water. Like Amazon frogbit, water spangles have surface clusters of textured leaves, but they also have very long roots. Depending on your aquarium depth, these may interfere with fish swimming. These plants also provide a lot of surface coverage, so deeper plants may not have enough light access.

Water Wisteria (Hygrophila difformis)

Water wisteria can grow very large and potentially overwhelm some aquariums. It is another plant that does well floating or being planted in aplant-friendly substrate. Unlike many other aquatic plants, water wisteria will grow sideways as well as lengthwise, which may crowd other plants in the same area.

Pennywort (Centella asiatica)

Pennywort, also known as centella or gotukola, is native to Asian wetlands. In addition to resembling tiny lily pads, this aquatic plant is used in cooking and herbal medicine.

Brazilian pennywortis also a popular floating plant option.

Rotala indica
