Benefits of Using Moss in your Aquarium

Mosses are not just optically pleasing. Yes, they make a beautiful aquatic scenery, but they also provide safety for your fish and shrimps.

  • They provide the ideal shelter for fish, shrimps, and their offspring.
  • It’s a great place for fish spawning.
  • Mosses don’t have roots, so they are easily movable and removable.
  • Mosses can make your aquarium look like a real underwater marvel.
  • Most of them grow at a slow pace, so they are easy to keep.
  • They adapt to almost any tank conditions.
  • They are suitable for any tank size.
  • They can improve the quality of your water by absorbing nitrates.

How to care for your Aquarium Mosses

Before discussing individual types of mosses, there are some general rules and things to note. Most mosses are easy to care for and rather undemanding. However, just like your fish need clean and filtered water to thrive, mosses do require some attention when it comes to the conditions in your tank.

Attaching Moss to the Substrate

Mosses don’t have roots, so they can be easily attached to various surfaces and substrates. Gravel, multiple stones, decorations, coconut shells, and other elements in your aquarium are suitable for mosses.

You can move and remove them at some point, but you should be careful not to disturb them once you’ve positioned them in place, as they need some time to adapt to the environment. Sometimes it takes days, weeks, or even months, but always give them time to attach and get used to the environment.

However, while most mosses are self-attaching to any substrate, some need to be tied with a fishing line or a thin thread.

Water Filtration

Needless to say, that you should always keep an eye on your filtration system when it comes to your fish. The same goes for mosses. Water filtration is crucial, as debris and other suspended matter in the environment can affect your moss’ growth and development.

Water hardness is also essential for your fish and mosses alike. Mosses thrive in low to medium hardness, so don’t forget to change your filter’s cartridges when the maintenance is due.

Water Temperature

When propagating aquatic moss, you should also pay attention to the water temperature. Most mosses thrive into moderately cold-water temperatures, but as a rule of thumb, keep your heaters set somewhere between 69-77 degrees Fahrenheit at most. It’s true that most fish also need a similar temperature to remain healthy and happy. Still, when it comes to mosses, depending on the type you choose, you need to consider if it fits into your aquarium world based on temperature as well.

Lighting Conditions

Just as any living thing, mosses need light to survive and grow. Although most mosses will adapt and thrive in various lighting conditions, some can be fast growing when exposed to a bright and powerful light source, thus, overshadowing others. We will touch on most moss types in this article, but always read the care specifications before purchasing your moss.

Pruning & Growing Pace

Some species of mosses have a fast-growing pace, so they need regular trimming to avoid overshadowing others. In other words, when your moss grows to a certain level, it can stop light penetration to the bottom layers, so other aquatic plants can actually die from the lack of light. However, some mosses grow at a slower and steadier pace and they don’t need much attention. Nevertheless, pruning is essential from time to time, not just for the appearance, but for the wellbeing of the entire ecosystem.


Algae is the number one enemy of mosses. It is almost impossible to keep your aquarium completely algae-free. At some point, you will see the green stuff growing on the moss or on the bottom layers. That’s why it’s essential to run your moss under water to wash it thoroughly. If your moss is already in the tank, you don’t want to risk pulling the whole bunch out, so try to take it together with the gravel or the stone that it’s attached on.

Some species of shrimps help fight against algae. The Amano shrimp is the top choice if you are having green hair algae problems. You can also make sure that your tank is always clean and in good condition by regularly cleaning its bottom with a siphon.

Now that you know the basic rules and guidelines for caring for your mosses, let’s explore what is available and your best options for your aquarium.

These are the best aquarium mosses to decorate your aquarium with.

  • Anchoring needs: self-attaching, but you can use a cotton thread or a thin fishing line to attach them to the position you want.
  • PH range: 6.0-7.5

Java moss has an excellent reputation overall. It is the most widespread on the market. It also has the reputation of being the most versatile and undemanding when it comes to maintenance.

There are many reasons why Java moss is preferred amongst others, but the main reason is that it is hard to kill. Once attached, it’s almost impossible to degrade or die. That is because it will grow in nearly every water and light conditions.

When it comes to lighting conditions, it grows best in medium lighting, but low or high lighting is okay. It has a relatively moderate to fast growth rate, and that’s why it needs pruning from time to time.

Java moss is excellent for decorating, but it also provides a safe place for spawning and shelter for your fish or shrimps. It is self-attaching, and you can create lots of shapes with it. You can attach it to a cave entrance and let it hang, place it upright on driftwood, or create a moss wall, and even little bushes or a moss carpet. Its bright green color gives your environment a natural look. You could definitely decorate your whole tank with it, then trim it and shape it however you want.

This batch of Java moss comes in a cup that measures around 2.5 inches. Don’t be fooled – at first, it might not seem like much, but when you take it out of the cup, you soon realize that it’s plenty. This generous amount might be sufficient for your tank if you don’t plan on decorating all of it with only the Java moss.

2nd Flame Moss (Taxiphillum Sp)


  • Water hardness: low
  • Temperature: 68-82 degrees Fahrenheit
  • Lighting: low to medium lighting
  • Rate of growth: slow to moderate
  • Anchoring needs: self-attaching, use any thread to attach it to any substrate. Attach it to hard surfaces like wood or stone.
  • PH range: 6.0-7.5

Flame moss has an attractive appearance, and that what sets it apart from other popular mosses. This one grows upwards, and its swirling shoots create a shape that resembles flames.

This type of moss doesn’t demand much attention. However, you should know a few things about it if you want to see it thriving.

Flame moss grows best when it’s fully submerged in water, so feel free to decorate your tank however you want. If it’s emersed, it will grow slower, so if you’re going to see its full potential, try to keep it fully submerged in water. Also, when it’s fully submerged, it can grow up to 3-4 inches long.

Just like Java moss, Flame moss doesn’t require special lighting conditions. It can grow in low to medium light just fine. Pay attention not to flood your tank with bright light, as too much can cause an algae bloom.

When it comes to temperature, between 68-82 degrees Fahrenheit is considered acceptable. It doesn’t require any special attention, like a heater, to stay alive and grow.

It can also grow on any hard surface, like wood or stone. Its dark green color and thick bunch formation can add interest to any aquarium.

Flame moss is self-attaching. It has a short adaptation period of maximum two weeks, so you shouldn’t encounter any problems when you place it underwater for the first time.

This ready to use Flame moss is excellent, as it comes already attached to a stainless-steel mesh. The pad size is 3″ X 3″, and you can use it as it is to create a live carpet/wall, or you can attach it to your various hard-surfaced decors using a fish line or even glue.

This dense bunch will eventually grow into even thicker bushes, giving your aquarium a beautiful foreground with lush green colors.

Be careful and don’t keep your algae-eating fish or moss eating shrimps in a flame moss decorated tank, as they consider it a treat.

This moss is great to have, as it doesn’t need much attention and care. It has a low to moderate growth rate, even with the help of fertilizer. It grows best when it’s fully submerged in water.

4th Crystalwort (Riccia Fluitans)


  • Water hardness: low to medium
  • Temperature: 59-86 degrees Fahrenheit
  • Lighting: low to medium lighting
  • Rate of growth: fast
  • Anchoring needs: Free-floating, has no roots, it can be attached using wire
  • PH range: 6.0-8.0

This fascinating aquatic plant is both intriguing and beautiful, mainly because it’s not precisely a moss. It’s actually a livewort, and it has a stunningly vivid green color that can brighten up any tank décor.

It has grown approximately one inch tall, and it’s mainly used as a ground-covering carpet. It also has a relatively fast growth pace, so it needs regular trimming.

Crystalworth is naturally found floating in ponds and slow-moving streams. So, it’s a plant that likes to float. If you want to attach it to stones or wood, just know that it doesn’t grow roots. Considering its fast growth rate, it can detach itself and float around in your tank once it reaches enough growth. That’s why it’s regarded as a high-maintenance plant. You could attach it to a mesh and use it as a carpet, wall, or you can place it all over your aquarium in bunches.

With this deal, you get three packs of 4Ă—6 cm, which might seem like a small bunch, but you can propagate them in water, as they tend to grow fast. Tie them wherever you feel they look good, put them in a mesh base, or let them float freely, and make sure you offer them enough light to thrive.

  • Lighting: low to medium lighting
  • Rate of growth: moderate to fast
  • Anchoring needs: it needs anchoring to gravel, rocks, driftwood
  • PH range: 5.0-6.0

This is a beautiful overhanging pant that adds diversity to your tank’s décor. The name comes from its resemblance to a real-life willow. It needs anchoring to grow, but it’s versatile. You can attach it on top of caves and watch its branches hang over them; you can put it on driftwood and even on gravel.

Its bright green hanging shoots need regular trimming. It prefers a more acidic environment, so keep your water’s Ph between 5.0 and 6.0.

It is a tricky aquatic plant, as it can quickly develop algae, so be careful with bright lighting. It thrives in low to medium lighting. It also requires a few days to adapt to its environment, so be patient.

It also needs more CO2 than other mosses in order to grow.

You can buy it in a cup, which is more than enough to get started. Make sure you anchor it properly and wash it thoroughly before placing it in your tank.

6th Phoenix Moss (Fissidens Fontanus)


  • Water hardness: low (soft)
  • Temperature: best between 59-77 degrees Fahrenheit
  • Lighting: low to medium lighting
  • Rate of growth: moderate to fast
  • Anchoring needs: it easily attaches to most substrates
  • PH range: 6.0-8.0

This is another beautiful-looking moss. With its bright green leaves when it’s growing, turning into olive-green when it reaches the plateau, this is one of the best aquarium mosses that you can decorate with.

Its leaves form specific and precise patterns. It can reach up to 5 inches, and it can create dome shapes that look beautiful.

In terms of water hardness, it prefers soft water. Be careful with temperature, as it cannot stand too high temperatures. Keep it between 59-77 degrees, or else it can start browning and eventually die.

Keep your bright light away, too, as it doesn’t need it. It can grow in low to medium lighting conditions. Bright light can rapidly start the browning process.

So, it’s a bit sensitive to temperature and light, but other than that, it’s suitable even for beginner hobbyists. You can create a carpet or attach it higher on rocks to create the dome effect.

Here you can get it in pads. It comes already attached to a stainless-steel mesh, so all you have to do is wash it with dechlorinated water and place it at the bottom of your tank to create a carpet or wherever you think it’s suitable.

If you are looking for something both beautiful and easy to keep healthy, this livewort is what you need. This undemanding aquatic plant can withstand harsh conditions and doesn’t require much attention.

  • Temperature: 73-86 degrees Fahrenheit
  • Lighting: medium to bright
  • Rate of growth: slow
  • Anchoring needs: it can be anchored above the water
  • PH range: 5.0-7.5

 This mainly star-shaped moss is definitely not for everyone, but it’s gorgeous and unique. It is not natively waterborne, so if you decide to fully submerge it in water, unfortunately, it will not live a long life. This aquatic plant needs a shallow water tank or some kind of terrain, rock, or wood that extends above the water.

Its appearance varies depending on its water accessibility. When it’s fully dry, the leaves gather around the stem, and they change their colors from green to brownish-red.

  • Lighting: low to medium
  • Rate of growth: slow
  • Anchoring needs: anchor it on driftwood

This bright green moss can grow into thick clusters, and the best news is that it doesn’t need to be fully submerged to thrive. As long as it has access to water, it will survive and grow.

It grows horizontally rather than vertically in a triangle-shape. It’s perfect for carpeting, and it can withstand harsh temperatures. It doesn’t need special conditions to grow. In fact, it’s fairly easy to maintain.

It has a slow growth pace, and it only needs moderate lighting, but it can survive with minimal lighting. The number one reason why it’s popular among hobbyists is that it helps reduce algae growth. This moss is perfect to pair with other types that quickly develop algae, as they can thrive together.

This one comes with a stainless-steel mesh that measures 3” x 3”. It can be propagated, and immediately placed into the tank. Use it for carpeting, or anchor it on driftwood and watch it grow.
