Floating Plants For Aquarium: Which Is Best?

Some of these floating aquarium plants are safe for the betta and their roots suspended in the tank water from the living plants floating above them. If you have a fish tank, chances are you have some plants in there as well.

Considerations When Choosing Best Aquarium Floating Plants

Before you go out and buy any old plants for your aquarium, whether floating or not, there are a few things you should think about. Let’s take a closer look at everything you should think about while deciding on the best setup for your tank.


One of the most important factors to consider when selecting the right plants for your tank is their lighting requirements. As you may have noticed from our descriptions of various floating plants, no two plants will have the exact lighting requirements. Some require a certain amount of brightness, whether high or low, but others may grow under various light levels.

It would be best if you looked at how powerful your aquarium light is and whether the plant’s lighting requirements are suitable with the lighting requirements of the rest of the tank. Furthermore, keep in mind that these floaters will block off a significant amount of light and provide shade for the people below.

Just keep in mind that not all other plants and fish prefer shelter or shade, though many do. The lighting conditions must be carefully considered.

Flow of Water

The second factor to consider when buying floating plants for your aquarium is if the plants prefer strong currents, gentle currents, or no current at all. If you have fish that prefer strong currents, you can’t add floating plants that prefer no or low winds, and vice versa.

Also, some plants do not like currents, so if you have a strong filter, you will need to find a way to keep them away from it.

Hardness and pH

Another factor to consider before purchasing plants for your fish tank whether floating or not is the level of acidity and hardness they prefer. Most plants require a pH range of 5.0 to 8.0 but you must ensure that the pH requirements of your fish and other plants are identical to those of the new plants you want to add.

It would be best to consider water hardness, which measures the number of dissolved minerals in the water. These parameters must, once again, match those of the other tank dwellers.


The second factor to consider when adding plants to your tank is the temperature range they can withstand. Some aquatic plants can withstand a wide temperature range, usually no lower than 60 degrees and no higher than 89 degrees. However, this varies to ensure that your tank is at the right temperature and that all inhabitants can withstand that temperature.

Nutrients and C02

The third factor to consider is if your new additions require additional C02 and nutrient supplements. In general, you don’t want plants requiring more fertilizer to the water, as this may create algae growth.

The Advantages of Best Aquarium Floating Plants

With so many different kinds of floating plants for aquarium species to choose from, you can undoubtedly find one that meets your needs. In general, low upkeep. Another advantage of having at least one floating plant for aquariums is frequently relatively minimal maintenance. One possibility is that they do not need to be anchored in the substrate.

They have long roots that float freely in the water column and gather nutrients. These aquarium floating plants do not require a lot of light. They increase, and to keep them in check, floating aquarium plants like the ones we’ll look at today only need to be trimmed on occasion.


It is critical to provide adequate shading for your other aquarium plants and protection for your betta from light piercing the tank. Making a shade for the aquarium fish will show off their potential and various colors. The truth is that not all aquarium fish appreciate excessive light, and the same can be said for aquarium plants.

Many fish enjoy hiding under live plants, mainly because of their intrinsic urge to avoid predators from above; in other words, they provide excellent hiding places. Keep in mind that covering the entire surface of the aquarium with floating plants will substantially reduce the quantity of light that the rest of the tank receives, reducing the growth of other aquarium plants.

Just keep in mind that if you opt to cover the entire surface of your fish tank, it may slow the rate at which your other plants develop, so don’t overdo it.

Another factor to consider is that fish often love consuming plants, whether rooted or floating aquarium plants.
