Oh my God, We love Guppy Grass! Staying inside the aquarium and adding health and beauty to a community aquarium is very rewarding to see the green color of the green.

the grass is also versatile – you can either put it on or keep it afloat. Either way, it will be an advantage for your aquatic friends and will enhance the charm of your aquarium.

weeds are easy to grow (well, sometimes a little too easy!) And it helps keep your water clean. Fish and small ornaments hang around and get out, or use it as a spawning ground. It also provides plenty of hiding place and is a source of food.

As long as you can control the rapid and rapid growth of these freshwater aquatic plants you will be grateful to have it in your aquarium. We will cover all the important information about Guppy Grass, how to plant and care for them, the benefits of Guppy Grass and how to prevent it from getting out of hand and melting.

Also known as najas grass or common water nymph, guppy grass (scientific name najas guadalupensis) remains one of the most popular aquatic plants. A fast-growing plant, it is suitable for all aquarium enthusiasts from newborn to sure.

Some novice hobbyists might say, “You got me to say ‘easy to grow’, but these greenhouse plants have only one advantage – they also remove toxins and impurities from the water while creating oxygen.”

Just as spider mites and chrysanthemums clean the air in your home,  grass clears the water situation. Gupasi grass consists of the Najas aquatic nymphs (aka nides), a group of about 40 aquatic plants that were first described in 1753. You can see that other names for Guppy Grass come from their genus (najas) and plant species (water nymphs).

Previously classified into the Nazadassi family, these were reclassified in 2003 and now belong to the Hydrochritesi family. The common name of  Grass may make you think that it is not only a suitable plant for Guppies, but it is much more versatile than that, providing shelter, nutrition and sparring quarters of small fish, fried and small invertebrates.

Naja grass is a strong plant and therefore it is a worrying plant for novice aquarium hobbyists as it protects the water that any beginner can drink along with water conservation. Promotes the integrity of the water in your aquarium and the well-being of your community.


If you add too much to your tank, be sure to change the water, or forget to add a water conditioner, Guppy Grass is here for you. It absorbs so much dirt from the aquarium tank that you won’t see any algae growth. A good thing, but if you have to eat some shrimps and snails in Plicos, Live Carrier and Marine style, you may need to supplement them with diet sound waffles.

All you have to do is be careful about how fast this hardy plant grows – it can take over your aquarium if you are not careful.

Habitat of  Guppy Grass

Considered an invasive species in many regions, Naja grass is a North American native that is also found in South America, Asia and the Middle East.

It is not difficult to know what kind of water he likes and in nature, you can find him in calm and fast water and in fresh and thick water.

Whether it’s lakes, streams, ponds, canals, waterways or canals, you can find Guppy Grass. Check it out the next time you go out for a walk or a bike ride.

Benefits of Guppy Grass

The Naja Herbal Aquarium absorbs ammonia, metals, nitrates, nitrites and toxins from the water, so it is a real aid in the eternal pursuit of a hobby for an ancient tank. If you’ve ever read my articles, you know how much I advocate for a clean tank because it promotes not only health but also well-being.

A clean tank will not only protect your aquatic inhabitants from disease, it will also reduce their daily stress. Stress-free fish and invertebrates are happier, live longer, get along better with others, and display more vibrant colours. Since you can easily grow a common plant that can promote this common good, there is no reason not to add weeds to your aquarium.

And again, this would mean that you have to spend on these processes. Small fish like Danios, Rainbow Fish and Gruze prefer to use Najas grass as spring mop. The new fry guppies are protected under the grass and also use it as a source of nutrients (they stir in the infusoria attached to the grass). And the shrimp will also feed right on top of the microscopic food they find on najas grass and enjoy the secret places it provides.

Here is an alphabetical list of the main benefits of Najas:

  • Sent Absent Algae: By absorbing nutrients, grass does not leave enough algae to grow, greatly reducing the cleanliness that you would otherwise have to do.
  • Ractive Attractive Aesthetics: Grass gives a glimpse to your aquarium and truly complements the visual appeal of your community aquarium.
  • Food: Guppy grass is a great source of nutrients. Both dairy and cattle will crush the plant, and residents of other aquariums, including Bhaji, will grind the microorganisms they have found in the leaves of the guppy grass.
  • Iding Hiding Heavens: Many of our fish and aquatic friends rely on great places to hide and Grass does that strategy, providing protection and comfort.
  • Oh Oh Oxygen: The production of oxygen in your tank increases the health and well-being of the whole community
  • Water wash: Guppy grass ensures water quality in your aquarium, removes toxins, metals, nitrates and nitrates from the water.
  • Spanning Site: Egg Spreading, Live Carrier and Shrimp as a Spinning MOP relies on Grass and is protected from newly spread insect predators


The stalks of Guppy grass are long and slender with many branches. The leaves are also thin; They are flexible and green in color, arranged in a rotating stem

If you look closely, you will see that the leaves have tiny unicellular teeth.

Naja grass can reach a maximum height of 3 feet (0.91 m). Since it is a submerged plant, you will want to make sure that your tank is suitable for its growth to 1.2 inches (3 cm) long and 0.04 to 0.08 inches (1 to 2 mm) wide.

You will also notice small flowers and white roots of guppy grass.

 Habitat and Tank Conditions

As we mentioned,  weeds grow with very little effort, so you don’t need to add CO2, soil or fertilizer, although you can use a sufficient amount of liquid fertilizer. Freshwater Also, since these are accustomed to growing easily in a variety of water conditions, you can usually find the temperature and flow rate work best for your aquatic animal.

The Ultimate Guide to Guppy Grass Care – Guppy Fish

If you are in a floating state, you do not need a substrate to increase the grass. If you are planting najas grass you will need one type of layer but what you choose will depend on your type of fish.

For example, if you have a bottom feeder like a catfish, you may want to choose smooth sand because the pebbles can damage their bile.  the grass is not desirable about the substrate because it does not get real nutrients from the layer; The layer is just anchoring the plant.


In the case of illumination, Guppy grass grows best in low to medium conditions. If the light is too low, your trees will not be green. If the light level is too high, you run the risk of burning guppy weeds and the colour of the tree becomes redder than green. When growing and caring for grass, it is important to know the lighting conditions of other aquatic plants that you keep in your aquarium. If weeds are not pruned regularly, dense plant light sources can reach your other plants, snatch essential nutrients, and suffocate them.

Like any resident of a community reservoir, it is needed by the whole community and is essential for good health.

 The size of the tank

grass can survive in very small tanks; Indeed, a nano tank will work even, but due to the rapid expansion it is advisable to get a larger reservoir. If you are using a nano tank, it is likely to become too large for the tank too quickly. We offer a minimum of 15-gallon tanks.

Keep in mind that the size you need of the tank will depend on the number of fish in your community aquarium and others.

The state of the water or Water Conditions

As we mentioned earlier, the Guppy grass is a hardy aquatic plant that can be found as a single entity of water, still, fast or fast, fresh or granular, cool and warm.

The optimal parameters to ensure a close match with their natural habitat are:

  • H pH level: 6.0 to 8.0 (around 7.0 best)
  • Water hardness: 5 to 12 dKH
  • Water temperature: 68 F to 79 F (20-26.1 C)

The flow of water should be less for optimal growth of Guppy grass.

 Guppy vs floating grass plantation

You will have the option to plant your guppy weed or just let it float. The appearance of the leaves will vary depending on how you grow them. This means that the leaves will look different if you plant them and if you let them float.

Because fish don’t tend to feed on this plant, you should be able to let it float around without any issues. If you decide to plant this herb, keep in mind that it can break into several small pieces. While there is no guarantee that this will happen, you still take a chance.

Fertilization of Guppy Grass

While it’s true that guppy weed doesn’t absolutely need fertilizer to grow strong and healthy, it can definitely benefit from it. Liquid fertilizer is definitely your best option if you decide to do so. There are a number of great liquid fertilizers to choose from, so be sure to consider your options before making a decision. If you decide to plant this herb, you won’t need any root tabs.

How should I plant Guppy Grass?

Guppies can be weeded or left to float. The planting you decide will affect the growth of the leaves. Thus, visually, the appearance of the leaves will be different if the najas grass is planted in a level or left floating place.

This is important to remember because guppy grass is sensitive to changing conditions, so if you have a floating najas plant and try to plant it in the layer, you may fail and it may melt.

We also recommend the floating option because the Guppy grass does not feed on the substrate, so your plants can grow and perform better if not planted. Of course, you can decide to float and plant something for a variety of both location and appearance.

If you are having trouble digesting grass, be patient and don’t go crazy while adding fertilizer. It probably takes some recovery time and space to re-group them. Adding liquid fertilizer can act as a steroid and increase excess. It is better to rest and recover.

If you decide to plant your own najas weeds, divide the stalks evenly before placing them along the water column. If you prefer to plant najas grass, your branches should be split, but you should plant them at least two inches. Basically, you only hold the trees because the Guppy grass doesn’t have hard roots.

Tank Mates

By name, Guppy Grass presents itself as a tank companion for guppies. However, it is also suitable for small freshwater fish, dwarf shrimp, crabs and crayfish. It’s also good food for herbivores – there’s a chance they could kill the najas grass, but it’s so plentiful that it shouldn’t be a problem.

Care and maintenance for Guppy Grass

The best thing you can do for your tank and your  Grass is to prune it regularly in order to control its growth. If the growth is not controlled, all of its algae controlling properties will be gone and it can start to suffocate other plants and block light sources as well.

Plus, you might not have enough room in your aquarium for too much growth, so cutting and pruning every week or two can thin out dense plants and limit the growth of this lush aquatic plant.

Also, for the safety of other aquarium inhabitants, be sure to quarantine  Grass before adding it to your aquarium. Like any new addition, najas grass can carry parasites, pests, and predators that can endanger fish and other tank residents.

While it is possible to use pesticides to clean Guppy grass, it can be toxic to the fish and invertebrates in your aquarium.

Potential problems

Najas grass grows quickly and easily, so you need to make sure you prune and prune it regularly. Because  Grass is so dense, it can also block light to other plants in the aquarium and to fish that need more light. Regular cutting can alleviate this problem.

Another problem is that the rods are fragile and break easily. Watch for this as new side shoots will emerge from the breaking point and you will have more growth.

Finally, many aquarists complain about the melting of their  Grass. Although this is a sturdy plant, it does take time to adjust to a new environment, so allow time for it to get used to your tank and recover.

Growing (controlling!) Guppy Grass

grass growth is less strategic than grass control. As it grows and fades, the side shooters come out without any problems. If you cut them, those cuts will also increase.

You can use clippings in other tanks (if you have a separate spawning tank for any of your fish, you can keep clippings there). You can try to sell these or donate to your fish or local pet store, but if you don’t need them, make sure that removing the clippings won’t increase growth. Uncontrolled spills can block waterways and create real problems.

Is Guppy Grass Suitable for your Aquarium?

Grass can work wonders for the aesthetics and health of your community aquarium. Despite being considered an invasive species in many parts of the world, this is a great addition to your community aquarium.

A word of caution is that when you prune and control your najas grass plant, be sure to dispose of it by attaching it to your compost bin, burying it, and even dissolving it in water. Bleach – You want to make sure this is the case. Do not increase and block the waterways of your non-aquarium community.

I do not recommend using plastic bags for disposal as it is harmful to the environment. However, we recommend adding  Wade to your community aquarium, eliminating issues related to growth and disposal. You and your fish will love it!


  • Guppy weed requires a medium to the high amount of light to really thrive.
  • The more light you bring to this plant, the greener it looks. Too much light can cause it to burn.
  • Make sure you are maintaining a pH level of 6.0 to 7.0 and an average water flow. This grass will break easily if the flow is too strong.
  • You can either plant this grass or let it float. Most people choose to float it, as planting can be a bit tricky.
  • Fertilization is not necessary for these plants, but a good liquid fertilizer can promote growth.
  • This plant does not require a lot of maintenance, but you will need to prune it every now and then. This is usually needed every three weeks.
  • One of the only real possible issues with this herb is that it takes over and kills other plants in your aquarium. This is really only possible if you don’t maintain it at all.
  • Some of the best tank mates for this herb include Blue Velvet Shrimp and Green Fire Tetra.
  • This herb can oxygenate your aquarium and is perfect if you are going to be raising shrimp.

Guppy weed or Naja’s weed is one of the easiest plants to grow in an aquarium. This plant does not need a CO2 injection for its growth, it may seem strange, but it can also grow without fertilizer.
