Floating Aquarium Plants: All To Know

There are many ways to decorate a fish tank or pond in your compound. But, floating aquarium plants are the best way to rework your aquarium.

These plants can give your space a completely fresh look. They are the best choice if you are thinking of ways to give your tank an aesthetic appeal.

But now the problem is there are so many aquarium plants to choose from. Therefore, it may be challenging to decide which ones to introduce and which ones to avoid.

The first step to take if you’re looking for plants for your aquarium is to assess if your fish can tolerate the plant. You also need to consider the size of your aquarium when making this decision.

If you want some suggestions, you have come to the right place. Today we look at the top 15 floating aquarium plants you can consider. Please keep reading to learn about them.

What Are the Advantages of Having Floating Aquarium Plants?

Before reviewing the best plants, let’s start by looking at how aquarium plants can benefit your setup.

Of course, the most obvious one is that they make the surroundings beautiful, which is something all of us want for our environment. But, these plants offer other benefits apart from beauty.

For instance, they are super easy to grow and maintain. You’re already busy taking care of your fish in the pond or tank.

So the last thing you want is another burden to carry over your shoulders. Most aquarists love the idea of having plants in their aquarium. But only a few have the time, money, and effort to dedicate it to taking care of the plants.

Thankfully, floating plants need less time and money investments. Most of these plants don’t need a lot of effort to care for them. Occasional pruning should be enough to ensure the plants grow well.

Aside from that, these plants also offer shade for your fish, depending on which species you choose.

They protect your fish from too much light during the day, keeping them comfortable. However, please do not cover the entire tank with plants since underground plants also need light.

Another advantage is that floating plants help reduce toxins from the tank quickly.

So, you will not need to change water frequently to deal with nitrate. These plants also help aerate your tank. They supply your fish with oxygen which is crucial for their health.

Lastly, floating plants provide your fish with food. When you have them in the aquarium, it’s highly unlikely that your fish will be underfed.

These plants act as an automated food source and add nutrients. Hence, they can supplement the synthetic food and give your fish a balanced diet.

How to Choose the Right Floating Plant for Your Aquarium?

So now you know what benefits floating plants offer to your environment. The next important thing is to choose the right plant for you. Although it seems complicated, it doesn’t have to be.

Here are some factors to help you decide on the right plant to buy.

The Fish Species You Have

Some plants may not be favorable to your fish, depending on the species. Therefore, you should evaluate the animals in your pond before deciding.

Plants with roots help shelter newborn fish, making them comfortable. Thus, they are recommended for fish that reproduce.

On the other hand, if you’re dealing with a nitrate problem, you should opt for fast-growing plants like duckweed which can help absorb toxins and protect your fish.

How Fast the Plant Grows?

Most floating plants are fast growers. This is an advantage as they can quickly get rid of nitrate and provide oxygen to your fish. However, this fast growth rate also means that your tank becomes green quickly.

Even if you have small non-invasive plants, they can grow quickly and occupy most parts of your tank.

That’s why it’s crucial to consider the growth rate before buying a plant. Generally, a variety that grows quickly requires high maintenance since you’ll need to prune it regularly.

The Size of Your Pond or Tank

Smaller plants are suitable for smaller ponds. Remember that you don’t want to overcrowd your fish’s living space as it can cause stress.

When introducing plants, please factor in the size. If you have a large tank, it can accommodate several fast-growing varieties. But also, think of the capacity before you buy your plants.

Lighting

When adding plants to your aquarium, you should consider the lighting needs of other plants in the tank. Most floating plants provide cover and shade for fish.

However, they can block light from reaching the bottom of the tank, which isn’t good for plants growing beneath.

Your floating plants should allow some light to reach the tank’s bottom. Some varieties like duckweed are easily thinned out, allowing you to control the light penetration.

The Look You Want to Create

As earlier mentioned, floating plants help add aesthetic appeal to the surrounding. Therefore, having them in the tank will change its look and feel. So, you should visualize the type of look you want to achieve.

Shrimp and krill tend to forage in long-rooted plants and can fill a significant part of your pond with greener.

Most floating plants are suitable for a natural look that’s plant-filled. However, remember that some varieties grow quickly and can change the look of your surroundings within no time.

Top 15 Best Floating Plants for Your Aquarium

It adds a calm and relaxing mood to your tank. Its deeply green color changes the appearance and lighting of your aquarium. The leaves growing from its thin stem have a wispy look that makes the aesthetic more beautiful.

Since it’s a floating plant, you can pair it with most fish species. But, please research the fish species in your pond before introducing them to your pond.

Duckweed is a great floating plant for new aquarists. It is suitable for small tanks or ponds as it has short roots and small leaves. It allows enough light to pass through, meaning the plants growing below will not surface.

It’s a unique beauty to add to your fish pond or tank. The green leaves floating on the surface create a great space to look at.

The plant’s feathers provide ambient space for fish to hide. So, it supports the well-being of newborns. Additionally, you only need to check it out occasionally since it is an artificial plant.

#10. Water Wisteria

Water Wisteria is among the easiest plants to grow, making it suitable for beginners in the fishkeeping industry. It is also a versatile plant that you can leave floating on the water surface or anchor on a substrate.

The only problem is that you need a large tank to allow the plant to grow to its maximum height and spread up.

Also, you need to supply it with enough light and occasional pruning to keep the plant at its best. Please note that you shouldn’t grow this plant if you have snails, goldfish, or silver dollars, as they will eat it.

If you want to create a neat look, opt for this floating plant. It can completely change your aquarium’s look.

How fast the plant grows depends on the light provided. Moderate light can help control the development of this plant. It would be best if you also trimmed it regularly to maintain the neatness.

This is a unique plant as it doesn’t have an aquatic look like the ones we have reviewed above. But, it’s a suitable choice for people who want to add variety to their ponds or want something different.

The plant has green leaves that are truly outstanding. But on the bottom, the leaves are pink-red, which is what makes the plant unique.
