Are you setting up a planted aquarium? Growing a wall of vibrant live plants can add depth and movement to your aquascape, but which plants should you choose?
This article introduces 15 amazing tall aquarium plants for the background of your tank. Read along to learn more about each species and how to grow and care for them.
Let’s get started!
Key Takeaways
- Background plants are best in the back of your aquarium
- They typically represent stem plants, which have a fast growth rate and require lots of pruning
- Hornwort, Water Sprite, and Anacharis are some fo the easiest background plants to care for
The Benefits For Your Tank
Live aquarium plants have so many great benefits that it’s tough to know where to start! Aquatic plants are an important part of most freshwater ecosystems, so they make your fish feel right at home. Your fish will love exploring and hiding in tall aquarium plants, and some species will even lay their eggs in them!
Living plants take in carbon dioxide and breathe out oxygen, which is what your fish need to stay active and healthy. Plants also soak up excess nutrients in the water, which would otherwise cause water quality issues and even excessive algae growth.
Aquascaping
Plants benefit our tank environment in many ways that we can’t see, but there are also obvious aesthetic benefits to growing live aquarium plants!
A simple but effective aquascape concept for planted tanks is to plant tall aquarium plants (background plants) at the back of the tank, medium-sized plants in the middle, and low-growing plants in the front.
Tall plants at the back of the tank can also be used to cover up hardware like filters and heaters in the tank, and cables and other stuff behind your aquarium.
Best Aquarium Background Plants
Now that you know what background plants are, you’re probably wondering how to choose the best species for your tank!
You can use more than one individual plant species in the background, or use a single type. Whichever route you choose to go, it’s important to choose background plants that have suitable care needs and that grow to the right size.

Tank Setup
Creating a beautiful planted tank can be simple if you start out in the right way. Here’s what you’ll need:
Lighting
All background aquarium plants need light to grow, but some plants need more light than others. As a general rule, plants develop the best colors and a denser growth form under bright lighting.
Most of the plants in this article will grow well under moderate lighting conditions and it is better to provide medium light if you do not have injected CO2. Whichever light strength you choose, make sure you use a full spectrum light that is specifically designed for growing aquarium plants.
Substrate
The substrate is the layer of gravel or sand at the bottom of a fish tank. This layer can do two things for your plants. Firstly, the substrate provides an anchor point where your plants can attach themselves and grow from. The substrate also provides nutrients to the root zone of aquatic plants.
There are two basic categories of aquarium substrates:
Inert Substrates
Inert substrates do not provide your plants with nutrients. They provide your plant with a place to root and grow from, and they also create a more natural look in your aquarium. A gravel substrate is a great example of this type of growing medium.
Active Substrates
This type of growing medium is a nutrient-rich substrate that ensures healthy plant root growth. Use this type of substrate in heavily planted aquariums with loads of root-feeding plants. Not all aquarium plants need to take nutrients from the substrate, however, so avoid this type of soil if you are only growing column-feeding stem plants, epiphytes, or floating plants.

CO2 Injection
The next plant requirement you need to consider is carbon dioxide (CO2). This gas is what plants breathe in. Carbon dioxide occurs all around us, and it is naturally dissolved in our aquariums at low levels.
These natural levels are enough to sustain many aquarium plants, but if you want to see the best results, you’re going to want to increase the concentration. Many amazing aquarium plants just won’t grow well without injecting carbon dioxide into your aquarium. So how do you increase your CO2 levels?
Pressurized carbon dioxide systems are available as kits, which is probably the easiest route to go. These awesome systems are designed to allow you complete control over the amount of CO2 you dissolve into the water.

Filtration & Water Quality
All aquariums need quality filtration, including planted tanks. This essential piece of aquarium hardware filters out visible particles and also plays a vital role in regulating your tank water chemistry.
Aquarium filters come in all shapes and sizes, and many types will work well in a planted aquarium with background plants. I recommend canister filters for planted display tanks because they hold a lot of filtration media and can be housed outside of your tank, so you won’t see too much unnatural equipment when gazing at your beautiful plants and fish.

How To Grow Them In Your Tank
Read this section to learn the basics of growing and caring for live plants in the background of your aquarium.
Planting & Spacing
Planting background plants in your fish tank is very easy. Most background plants must be grown submerged, which means you’ll need to have your tank set up with your substrate in place and at least partially filled with water before you plant them out.
Stem plants are usually sold in bunches. You’ll need to separate the stems before planting them into the substrate individually. These plants will look a little thin when spread out in a row across the background of your tank, but they are usually very easy to propagate, so with a little patience, you can fill up the background in a few months. A more natural-looking option is to buy a few bundles of stem plants and plant them in bunches.
Rosette plants like Amazon swords and crypts are usually sold individually in pots. These plants grow more slowly, so it is best to buy as many as you need. They should not be moved around after being planted in the substrate, so take the time to plan your layout carefully.
Fertilization
Plants need access to nutrients to stay healthy and grow. Some plants will thrive without any added fertilizer because they get enough nutrients from fish waste, but if you plan on growing healthy background plants in a beautiful planted tank, regular dosing with a quality aquarium fertilizer is usually the way to go.

Different plants access nutrients in different ways. Root feeding plants, like Amazon sword, get most of their nutrients from the substrate. An active aquarium soil will provide them with most of what they need to grow. These plants can also be grown in inert substrates but will need to be fed with root tabs to sustain their growth in the long run.
Many stem plants like hornwort access nutrients that are dissolved in the water column and do not need a nutrient-rich substrate. These plants are known as column feeders and they will require regular doses of liquid fertilizer to grow their best.
Trimming
Most stem plants are fast growing under good conditions and will need regular pruning and trimming to stay neat and tidy. A good-quality pair of stainless aquascaping scissors will make this job much easier and more fun.
You’ll need to collect all the little bits of plant that you have cut and remove them from your tank before they begin to rot (video source). The best way to do this is to use a small aquarium net with fine mesh, but you can also siphon them out with a hose or your gravel vacuum.
Tank Maintenance
Growing live aquarium plants can have amazing benefits for water quality, but with poor maintenance, the opposite can also be true.
Melting plants and trimmings left to spoil in your water can even create toxic conditions for your fish. It’s important to remove all your plant trimming and any melting/dying growth as soon as possible.
As with any aquarium, a regular maintenance schedule will keep your tank healthy and looking beautiful in the long run. Use your aquarium test kit to keep an eye on your parameters.
Regular partial water changes will reset the nutrient levels in your tank and keep your water safe for your fish and plants.
Pests & Other Problems
Most of the popular freshwater fish can be kept in planted tanks without any problems, but some species are notorious for destroying live aquarium plants. These are some of the fish that you should avoid:
- Goldfish
- Silver dollars
- Buenos Aires Tetras
- African cichlids
Algae growth is the most common problem in planted tanks. Solving algae outbreaks can be tough, but you’ll almost always be able to succeed by making a few changes to the following:
- Tank maintenance schedule
- Lighting
- Carbon dioxide levels
- Fertilizer use
- Plant numbers
- Water temperatures
Where To Buy Them
Many of the background plants in this article can be found at your local fish store. Another great way to buy your plants is to order them online from trusted experts in the field. Where it is rare to find tissue culture plants when it comes to backgrounds plants, if you can find them buy them as they are pest free.
