Live plants will take your tank to the next level.
Not only do live plants make a tank look better, but they also benefit the inhabitants of your tank by absorbing toxins, suppressing algae, and providing cover.
This guide will go over everything you need to start your own planted aquarium as well as specific fish and plant recommendations for your tank.
Step 1: Get a Tank

The most obvious piece of equipment you need is an aquarium.
The factors that matter most when selecting an aquarium are size, shape, and clarity.
Size:
Almost any size of aquarium can be used to set up a planted tank, but aquariums between 5 to 20 gallons are some of the most popular sizes, likely for practical reasons like space, and cost.
My favorite size for a planted tank is a 5 gallon because the limited space inside a 5 gallon means that more thought and planning is needed to create a cohesive design.
Setting up a planted tank in a smaller aquarium also means using fewer plants, rocks, and wood, which reduces the cost of the setup.
But, smaller tanks also have a big disadvantage, only a small number of fish can be kept inside.
So, when selecting a tank, consider the types of fish, and how many, you plan to keep in your planted aquarium.
If you are curious about which fish do best in a 5 gallon, check out my article on the best fish for a 5 gallon aquarium.
Shape:
Shape is not a crucial factor, but should be given some thought.
In the aquarium hobby, rectangular tanks can be found everywhere.
Square tanks (sometimes referred to as cube tanks) are also widely used, especially amound aquarists that love aquascaping.
Round tanks also make excellent planted aquariums but are less common.
While most round tanks (think fishbowls) available in pet stores are too small for keeping tropical fish, larger bowls are available online.
If you want to learn more about bowl aquariums, check out my article and video on setting up a betta bowl, which will explain why most bowls are not suitable for betta fish or any other tropical fish.
Clarity:
Glass clarity is not important to everyone, but if you want to see every detail on your fish, or shrimp, then having a tank with high clarity is crucial.
In the aquarium hobby, the tanks with the clearest glass are called “low-iron aquariums.”
As the name suggests, low-iron aquariums are built with glass that contains less iron, creating an optically clear and nearly colorless viewing experience.
Low-iron tanks are also typically “rimless,” which means that are assembled without plastic supports.
This gives the tank a more elegant look, but also means seams of the aquarium may be more fragile.
Step 2: Get a Stand For Your Tank

Having a stand, or a steady and even surface, for your fish tank to sit on is important because water is heavy.
In fact, 1 gallon of water weighs about 8.3 pounds; this means that a 10 gallon tank weighs 83 pounds plus whatever the glass or acrylic weighs.
So, when selecting a stand for your aquarium, make sure it can support the weight of the water your tank will hold plus a few extra pounds just to be safe.
Should You Buy A Stand Made For a Specific Fish Tank Size?
The problem with most stands made specifically for fish tanks is that they tend to be expensive and uninspiring to look at.
A cheaper and often better looking option is to buy a side table or shelf not specifically made for aquariums.
Side tables in particular are great for smaller tanks like 3 gallon bowls and 5 gallon cube tanks.
Just make sure they are rated to hold the necessary weight (I look for tables that can hold 200+ pounds).
If you plan to set up a planted tank in a larger aquarium, say 20-40+ gallons, then I would look for more specialized stands, or consider buying an industrial workbench (these can support significant amounts of weight).
Step 3: Add Planted Aquarium Substrate

The best substrate for your planted tank is the substrate that helps you grow healthy, vibrant plants.
If you plan on having nutrient hungry Amazon Sword plants in your tank, then you’ll want to provide a nutrient rich substrate, or a mix of substrates, to keep your plants happy.
One of my favorite substrates for live plants is Eco Complete.
It contains nutrients and I find that it holds plant roots especially well, preventing them from constantly floating to the surface.
Fluval Stratum is also an excellent substrate for planted tanks.
It doesn’t hold plant roots as well as Eco Complete, but the miniature spheres of volcanic material give Stratum substrate a unique look.
If you want to learn more substrates and gravel, check out my article on the best substrates for planted tanks.
Step 4: Add Hardscape

What is hardscape?
In the world of aquascaping (carefully designed planted tanks), hardscape refers to stones and driftwood.
Some of the most popular hardscape used in planted tanks include:
1. Seiryu Stones
2. Dragon Stones
3. River Stones
4. Malaysian Driftwood
5. Mopani Wood
6. Spider Wood
7. Manzanita Wood
Not all stones and driftwood are aquarium safe, so avoid collecting random pieces of wood and rock for your tank.
Step 5: Add an LED Light

Plants need light to photosynthesize.
Photosynthesis allows plants to absorb water (H2O) and carbon dioxide (CO2), and ultimately produce oxygen and glucose by removing electrons from the water molecules and adding electrons to the carbon dioxide molecules.
At the end of the photosynthetic process, plants release the oxygen but store the glucose as a source of energy.
But, not all types of light is used by plants.
The light used by plants is called Photosynthetic Active Radiation (PAR) and refers to a range of light colors in the 400-700 nanometer range.
In the context of aquariums and planted tanks, the best lights are those that provide a sufficient mix of light colors (spectrum) while also being strong enough to reach plants at the bottom of a tank.
Step 6: Add Aquatic Plants

A huge variety of aquatic plants exist, but only a small fraction are available to purchase in a pet store.
And, of the plants that are available, only a small number are suitable for beginners setting up a planted tank.
Selecting the right plants for your aquarium depends on how you want your tank to look, and how much maintenance you want to put into caring for the plants.
If you need some inspiration for how to design your planted tank, and want to learn about aquascaping styles, check out my article on easy aquascaping ideas, it contains a variety of tutorials on small tank aquascapes.
How Important is CO2 and Aquarium Plant Fertilizer?
In tanks that do not use supplemental CO2, aquarium fertilizer is less important because plants are not able to grow as quickly due to the limited amount of natural CO2 in the water.
But, in tanks that do use CO2, dosing plant fertilizer consistently is an important part of growing healthy and vibrant aquatic plants.
Is CO2 necessary for growing live plants in an aquarium?
No, but it does increase plant growth dramatically.
Most of my tanks do not use CO2 because I enjoy keeping low maintenance tanks.
But, if you want your plants to achieve their fullest potential, and grow rapidly, consider installing a CO2 system.
Step 7: Add Water

Before dumping a bucket of water into your tank, or turning a hose on full blast, find a large piece of bubble wrap, or a plastic bag.
Place the plastic over the top of your plants, stones, and wood.
This will help prevent the water your add to the tank from dislodging your hard work.
Step 8: Add an Aquarium Heater

Many commonly availableaquatic plants are from tropical climates, and do best at temperatures between 74-80 Fahrenheit (23.33-26.67 Celsius).
Most tropical fish, and shrimp, also do well within that range.
But, if you plan to set up a cold-water tank (generally defined as temperatures below 70 Fahrenheit) then you should use plants that also prefer cooler temperatures.
Step 9: Cycle Your Tank

In general, cycling an aquarium involves filling up your tank with water and waiting about 2-4 weeks for nitrifying bacteria colonies to establish themselves.
The amount of time that your tank needs to sit is dependent on a variety of factors, including temperature, size of tank, and how many fish you plan to keep in your tank.
If your tank is small (5 gallons or less), it should cycle quicker because fewer beneficial bacteria are needed to establish a functioning nitrogen cycle.
But, no one likes waiting 2-4 weeks to add fish.
Luckily, there are a few things that you can do to help the beneficial bacteria establish themselves more quickly and allow you to add fish sooner.
1) Add a Used Aquarium Filter
Sponge filters that have been filtering someone else’s tank are especially helpful for adding beneficial bacteria to your new tank.
If you have a friend or fellow aquarists willing to lend you one, simply place the sponge filter (do not rinse it) in your new tank for about 10 days.
If you plan on giving the filter back, consider placing a second sponge filter in your tank at the same time.
This allows the “used” sponge filter to pass beneficial bacteria to the new filter.
Having two sponge filters in the tank at the same time might look strange, but it’s a great way to help a new tank cycle quickly.
2) “Starter” Fish Method
The starter fish method is not something I recommend, it’s still practiced but is completely unnecessary.
This method involves adding hardy community fish to a new tank.
The waste produced by these fish typically spikes the amount of ammonia, which spurs the growth the nitrifying bacteria that process the ammonia.
The problem with the starter fish method is that the high amounts of ammonia, nitrites, and other substances will stress the fish, and may lead to disease and death depending on how bad things get.
Certain fish are better at handling these conditions than others but there are better methods for cycling a tank.
3) Cycling a Tank Without Fish

Fishless cycling typically involves setting up a tank and then adding commercially available ammonia to the tank to jumpstart the nitrogen cycle.
Many aquarium specific ammonia products exist and provide dosing instructions, but online aquarium forums and YouTube videos are also for getting an idea of how dosing ammonia works.
At a basic level, the three most common ways to cycle a tank without fish are:
A) Adding Pure Ammonia
Pure ammonia is typically dosed at about 5 drops per 10 gallons of water.
This may not be the best method for beginner aquarists, unless they have done sufficient research, ammonia is corrosive and can be dangerous.
Dosing ammonia is also labor intensive, the aquarist will need to dose ammonia daily until testing reveals significant nitrites.
Then, dosing can be reduced until nitrates are detected.
Once testing reveals that nitrates are present, perform a 30-40% water change, and your tank will be ready for fish.
B) Dosing Live Nitrifying Bacteria
Adding live nitrifying bacteria directly to the tank is also an excellent way to cycle a tank quickly.
Live nitrifying bacteria can be purchased from sites like Drs. Foster and Smith or your local fish store may carry it.
Tetra Safe Start, Bio-Spira, and Dr. Tim’s are a few of the brands recommended by fish keepers, but many more options exist as well.
In the saltwater aquarium community, adding beneficial bacteria to help a tank cycle is common practice, but in the freshwater community it seems less popular.
If you don’t mind spending the money, give it a try, your tank may cycle faster.
C) Add Fish Food
A simple and affordable DIY method for cycling a tank is to drop some fish food into your new tank and let it sink to the bottom.
As the fish food decomposes, it will release ammonia, which jumpstarts the growth of nitrifying bacteria and begins the nitrogen cycle.
While affordable, there is a potential downside to the fish food cycling method.
Tropical fish food contains a wide array of nutrients, including phosphate.
These nutrients get released into the water column as the fish food breaks down, creating the perfect environment for algae and less desirable bacteria to explode in growth.
Using this cycling method may result in your tank going through an “ugly” phase where the water gets cloudy and/or green.
It should clear up as all nutrients are absorbed, but you may want to do some maintenance/algae scrubbing before adding fish.
Adding aquatic plants (before using the fish food method) may lessen the severity of the ugly phase, give that a try if you are interested in trying this cycling method.
D) Add Plants
The fourth fishless way to cycle your aquarium involves adding aquatic plants that have been growing in an established tank.
This works best if the plants have actually been growing underwater, giving the right kind of bacteria a chance to colonize the roots and other parts of the plant.
If you order your aquatic plants online, there’s a good chance the plants were grown in greenhouses outside the water (it’s easier for the grower), and lack beneficial bacteria.
Tissue culture plants, often grown in little cups, are also not ideal for this method as they grow in a gel solution that lack beneficial bacteria.
If you want to cycle your tank with plants, find some aquarium plants that have been growing in an old aquarium that has been running for years (if possible).
Then add these plants to your tank and wait 10 days.
Keep testing your water everyday after that until you detect nitrates. Then it should be safe to add fish.
Step 10: Add Fish and/or Shrimp

What are the best fish for a planted tank?
The best fish for a planted tank are the ones that do not eat your plants or constantly uproot them.
Thankfully, most commonly available aquarium fish are not interested in eating or messing with plants.
My favorite tropical fish to keep in planted tanks are fish that seem to take comfort in the presence of plants, or utilize plants as places to rest.
For example, Otocinclus and Pygmy Corydoras both love resting on leaves and using plants as hiding places.
One of my favorite fish to keep in a planted tank is not a fish at all, but a freshwater shrimp.
Cherry shrimp come in a variety of colors and look stunning in planted tanks.
They will crawl over every inch of plant material looking for algae to eat.
This makes makes them one of the most interesting creatures to keep in planted tank.

Planted Betta Tanks

One of the best fish to keep in a planted tank is a betta fish.
In the wild, betta fish are often found in ponds and small pools of water that are covered in dense vegetation.
Sadly, far too many betta fish are kept in a bare tank or bowl.
In my experience, betta fish live longer lives, and appear to be more active, in planted tanks.

What are the worst fish for a planted tank?

The least ideal fish for a planted tank are the ones that munch on plants and uproot them by digging around in the substrate.
Fish like Silver Dollars, Pacu, Goldfish, and Fire Eels are wonderful to keep, but tend to decimate live plants.
Silver Dollars and Pacu are plant eaters and are known as “plant piranhas” because they will shred any plants they find.
Goldfish can be kept in tanks with certain live plants (Anubias, Java Ferns and a few others), but may pick at and eat others types of aquatic plants. They also tend to uproot plants.
Fire Eels are not interested in eating plants, but do love burrowing in substrate.
This means that plants will get uprooted and need to be replanted frequently.
This makes the Fire Eel especially interesting creature to keep, but not ideal for carefully designed planted aquariums.

This video shows, step by step, how to create an island style aquascape using seiryu stones and spiderwood branches in a cube tank. Cube tanks look stunning, and make excellent aquariums for planted tank setups.
Planted Aquariums vs Aquascapes
What’s the difference between planted aquarium and aquascapes?
The way I see it, all aquascapes are planted aquarium, but not all planted aquariums are aquascapes.
Aquascapes are a subset of planted aquarium that focus on design and fidelity to nature.
For example, Dutch aquascapes focus entirely on plants of different sizes and colors, no stones or wood are used while Iwagumi aquascapes focus on the balance between open space and large stones, creating a scape that resembles grassy fields punctuated by huge boulders or crags.
And some aquascapes simply mimic nature, like a particular lake bed, or portion of river where tropical fish live.

Conclusion
Planted tanks are rewarding to build and maintain.
Choosing where to place a stone or piece of wood is meditative and takes us out of our digitally focused lives for a time.
I hope this article provided you with the information and inspiration you need to set up your own planted tank, or if you are looking for a challenge, to create a carefully planted and designed aquascape.

FAQs
How do you make a planted aquarium step by step? ›
- Step 1: Set-up and Start with Quality Plant Substrates.
- Step 2: Test and Regulate pH Levels and Hardness (KH)
- Step 3: Add Light Fixtures.
- Step 4: Add Aquatic Plants.
- Step 5: Add Fish.
- Step 6: Add Supplementary Plant Nutrients as Needed.
In aquascaping you should always keep your focus on aquatic plants rather than the fish. And at the start of a new aquascape is always better to have more plants than fish, especially long stem plants, which have a higher growth rate which will help in absorbing the extra nutrients from the water.
How long to cycle a planted aquarium? ›Eventually, even with additions of ammonia, nitrites and ammonia would measure at 0 after a 6hr period, while nitrates accumulate. The ammonia cycling process for the tank is now complete. The entire process can take 4-6 weeks depending on tank parameters.
Can you put plants in an uncycled tank? ›A common misconception to most novice fish keepers is that plants cannot be added to an uncycled aquarium. The first notion is that the plants will die off causing further problems but this couldn't be further from the truth.
How deep should substrate be in planted aquarium? ›How much substrate do you need? The general recommendation is at least 3 inches. Not only will this amount be pleasing to look at, but it is also deep enough to allow plants to root without floating away.
What substrate for beginner planted tank? ›Substrate: Many newcomers use an inert and/or non-nutritive substrate such as gravel, pebbles, rubble, or sand in their tank. The type used will affect what you can and cannot plant—or whether you can plant in the substrate at all. A key point is grain size.
Can I mix gravel and plant substrate? ›It is recommended to use rocks or other forms of decoration between each substrate as a barrier to prevent them from mixing together over time. Many aquascapers add onto this method by placing some gravel around the rocks to create the illusion of depth, so they use all three of the main types of substrates.
What is the rule of thirds in aquascaping? ›The “thirds” refers to sectioning the visual display—the aquarium in this case—into thirds. Placing key corals, decoration and plants in these intersections will make your aquarium more pleasing to the eye. Some take this very literally and apply masking tape to the front glass in the pattern of a Tic Tac Toe board.
Can I do aquascape without CO2? ›Plants definitely grow better with the addition of CO2, but some plants don't need additional CO2 at all. A thriving, healthy planted aquarium can be created without CO2, as long as you choose the right plants, and light it accordingly.
What do aquarium plants need to thrive? ›Aquarium plants require clean water, light, nutrients for growth, and in some cases, a proper substrate like soil. Whether your aquarium plant requires soil or not, will depend on the type of aquatic plant you have.
What temperature should planted aquarium be? ›
A very common temperature that aquarists keep their aquariums at is about 78F (~25.5C). Most aquarium plants do well at this temperature if they are kept in their ideal conditions (e.g. sufficient CO2 level, a good source of light, enough nutrients).
How do I know if my planted tank is cycled? ›You should be detecting some (0.25 to 0.5 ppm), which means your cycle has started. Depending on the plant species you have, you should see noticeable growths in some of them, and your plants also help to cycle your tank (if your plants came with roots already, those roots have the beneficial bacteria already too).
How long can a planted tank go without a water change? ›Conduct a water change of a minimum 30% each week. This prevents the build up of organic waste which algae thrive on. During the first 2-4 weeks you should be changing the water more often until your tank matures.
How often should you do water changes when cycling a planted tank? ›Aim to do 10-25% water changes every 2-3 days. Any more, and you'll risk removing the ammonia and nitrite that beneficial bacteria needs to feed on. Make sure you add de-chlorinator to the water. Adding chlorine/chloramines will kill the bacteria and ruin the cycling process.
Is sand or gravel better for planted tank? ›Sand is usually so compact that plant roots have difficulty growing and spreading out. Like gravel, sand also does not provide nutrients for the plants. Even with the addition of root tabs, it is not the best option for a planted aquarium.
Do you need soil in planted aquarium? ›While some aquarium plants can absorb nutrients via their leaves and do not require a substrate like soil, many aquarium plants that grow from a bulb and absorb nutrients through their root system, require soil to survive. Soil also acts as a great, sturdy anchor, keeping your aquarium plant upright.
