Low maintenance floating aquarium plants

If you’re in a hurry and eager to find out the best floating aquarium plant. Then we would recommend JavaMoss.

Aquarium plants should be at the top of your list if you own an aquarium or are planning to start one. With an extensive range to choose from, there will always be one to match your specific needs. Aside from the aesthetic appeal, plants will add numerous benefits to your fish tank. Below we’ll explain what these benefits are and recommend what we believe to be the best floating aquarium plants that both you and your fish will love!

What are the benefits of floating plants? 

1.) They provide shade 

Since the plants float on the water surface, this helps to inhibit light. Certain fish species prefer shady environments, and by having shade this will help reduce their stress levels, keeping them comfortable. That being said, this is dependent on the fish as some species may prefer well-lit waters. It’s crucial to fully understand how much light your species of fish will require. 

2.) They act as additional food Source

Certain plants can be highly nutritious and for herbivorous fish species, they can provide the perfect snack. 

3.) Provide aeration

Floating plants add substantial amounts of oxygen to your fish tank. They act as a plant aeration system to generate high amounts of oxygen in the tank. Which will help safeguard the aquarium against toxins.

4.) Minimal maintenance

Floating plants will proliferate faster and are easy to keep, allowing you to focus on fish keeping instead of plant maintenance. Most of them require no extra effort besides the occasional pruning when overgrown. 

5.) They give your aquarium a jungle appearance

The plants will give your fish tank a natural, healthy, and wilderness appearance, increasing your fish’s comfort level. 

How to decide on the best plants for you!

Now that you know what floating plants can offer. Below are some things you should consider when choosing the best plant type. 

Aquarium size

If your aquarium holds less than 40 gallons, then you may consider smaller plants. Naturally, those with a bigger tank can accommodate a wider variety of floating plants.

Lighting

Plants will provide your fish with low light areas. This can however be detrimental to the plant species’ health at the bottom of the tank. Therefore, allow enough lighting to keep your plants at the bottom in those areas out of the dark. However, some plants can thrive in lower lights, which you might want to consider having. 

Speed of Growth

Some plants will grow considerably faster than others, which will, therefore, require regular pruning. It’s important to consider the size of the tank before purchase. To prevent buying a plant that will quickly overrun your tank. 

Type of fish

The fish you have or plan to keep will play a role when choosing the correct plants. For example, if you plan to breed fish, opting for floating plants with roots that provide shelter for the fry (baby fish) would be wise. 

7 Tips on how to best prepare for planting

1.) When the plants arrive, remove the wrapping bag, tear the rock wool from the roots, and then split the plants carefully using scissors.

2.) If a plant has elongated roots, you can trim them to a length of about 2-3 centimeters, to encourage new and healthy growth.

3.) You will need to remove any pigmented or dead leaves to allow new leaf growth since the colored leaves may decay in the aquarium.

4.) Since the plants are floating, you only need to pick and place them on the water surface. However, remember to position the leaves right up. Also, ensure that the water flowing beneath isn’t too vigorous that it overturns the plants.

5.) Space out the plants adequately to give them enough growing space, about 3-4 centimeters apart. If you have larger plants, you may need to give more space. 

6.) Research your plants’ feeding habits and get the appropriate fertilizers to bring up healthy and thriving plants.

7.) Invest in functional lighting for your plants to promote continuous growth. However, note that excess light can encourage the growth of algae, therefore, you will need to control the light exposure.
