Adding plants to your aquarium serves a variety of functions. Plants will help to maintain the tank and the fish in it considerably healthier by doing anything from oxygenating the water to giving shade.
Freshwater plants such as hornwort are among the most straightforward to cultivate. Following its origins in North America, it has achieved great success in the wild, spreading to every continent except Antarctica after having spread around the world.
As a result of its strong tolerance to a wide range of water conditions, it is an excellent choice for beginning gardeners, and because of its rapid growth rate and ease of propagation, a little amount goes a long way with it.
The fact that it may be utilized as a floating plant or one that is planted in the substrate gives you more flexibility when it comes to customizing the appearance of your aquarium.
The number of freshwater fish that may benefit from it is likewise expanding as a result of this development.
hornwort is a good choice if you want a plant that is simple to cultivate and grows quickly. A quick rundown of what you may anticipate is provided below.
Freshwater aquarium plants like hornwort, also known as Ceratophyllum, are quite trendy right now. The number of species is an unknown quantity at this point in time.
Approximately 300 species names have been reported, however owing to misidentification, it is probable that there are only 100-150 species.
The species Ceratophyllum demersum is the most often seen in aquariums.
For novices or those wishing to add a less picky plant to their aquarium, its resilient nature makes it an excellent choice.
In an aquarium, being hardy is advantageous; but, in the wild, it might be detrimental. As an invasive species, it is able to spread to new places because of its high tolerance for a broad variety of environmental conditions, along with its rapid growth rate.
As a result, it has become a concern in locations such as New Zealand, where it is outcompeting native plant species and interfering with hydroelectric power generating.
In addition to its anti-allergic properties, hornwort is a popular medicinal herb. In other words, it has the ability to create compounds that inhibit the development of other species, allowing it to flourish and thrive in the absence of competition for resources and space.
There are several areas across the world where this plant may be seen demonstrating its accomplishments — it has a really international reach. Except for Antarctica, this plant may now be found on all continents.
This plant is in great demand as a consequence of its widespread use, and as a result, it can be found in a wide variety of retail establishments.
It is frequently offered at a low price because of the quick growth of this species, which allows it to be produced in large quantities for little money, allowing it to be manufactured at a low cost.
It will cost $5-$10 to purchase a few bunches of hornwort, but pricing per plant may vary depending on the shop and how many plants you purchase at once.
Using Hornwort Has Many Advantages
An attractive appearance is one of the primary reasons for including hornwort. Adding plants to your tank will improve the amount of color in your tank, whether they are floating at the top of the tank or rooted in the substrate below the water level.
As it sways in the current, it also offers your aquarium a unique dynamic. But what most people don’t think about is how it contributes to the overall health of your tank.
Horehound photosynthesizes in its natural state as a plant. In photosynthesis, oxygen is the most important byproduct.
The oxygen in the tank will be increased as a consequence of this. Furthermore, it offers regions of refuge for fish that are trying to get away from one another or from the sun.
Such plants may also be utilized as a nursery for fry; another excellent plant for this is java moss, which is also found in abundance in the United States.
Occasionally, they may expel debris, which will most likely be consumed by scavenging fishes as food.
It also contributes to the improvement of the water’s quality. It takes up minute quantities of waste produced by fish, as well as nitrogen compounds, allowing the water to remain cleaner and the filter’s job to be lessened.
Finally, the allelopathic properties that we have previously discussed may be used to prevent the development of blue-green algae from flourishing (cyanobacteria).
This is an alga that may rapidly go out of control when exposed to excessive light or a large amount of organic waste.
Aesthetics of hornwort
Most of the time, a single plant will have several stems, giving the appearance of many plants. True roots are absent from Hornwort; rather, specific leaves work to assist the plant in anchoring itself to its surrounding environment (see illustration).
The plant may also develop rhizoids (hair-like roots) to aid in the stabilization of the plant’s structure.
The attached stems might grow all the way to the surface of your tank, with 0-3 branches at each node if left to its own devices. It may grow up to 10 feet long and 1/10 inch in diameter in its native environment.
A whorl of six to twelve leaves (or needles) is created in the production of a leaf (or needle). In most cases, the fork just once or twice before remaining quite short, usually less than an inch in length.
Typically, this is a dark green plant with darker green tints, while lighter green colors may be seen in warmer climates.
A crucial component of reproduction is the hornwort, which blooms in the spring. This plant is monoecious, meaning that it has both male and female flowers on the same stem. Because the blossoms are brown and just 1/10-inch long, don’t anticipate much in the way of color.
Approximately 1/5 of an inch in size, with three spines, the nut produced by the bloom is about the size of a pea.
Instructions for Growing and Maintaining a Hornwort Plant
Ceratophyllum demersum (Hornwort) is a plant that grows in water.
Specifications for the Tank
Hornwort may be found growing in a variety of habitats, including lakes, rivers, ponds, and marshes in its natural environment. These settings each have their own set of structural components that are distinct from one another.
There is no one proper method to construct a tank to accommodate hornwort because of the wide range of natural environments available. Almost all environments should allow it to thrive.
This covers a variety of tank sizes since it will grow to accommodate large tanks and may be trimmed to fit smaller tanks on a regular basis..
In order for the plant to maintain control over its rapid development rate, it should be housed in a tank no less than 15 gallons.
In a temperature range of around 59-86°F, they are comfortable. In order to accommodate both cold-water and tropical environments, it is often used. pH may be anywhere between 6.0 and 7.5, and hardness should be between 5 and 15 dGH.
It is necessary to filter water to maintain nitrogen compounds (ammonia, nitrites, and nitrates) at a low level (ammonium, nitrites, and nitrates), but there are no other specific needs.
It is photosynthesis that is the focus of the few requirements they do have for growth. For example, strong light intensity and clean water are required so that the light may reach all parts of the aquarium.
Performing frequent partial water changes will help to keep your water as clean as possible.
A tank’s supply of nutrients will soon be depleted if hornwort is housed with other plants. Then it may be necessary to apply fertilizer once a week in order to keep supplies from running short.

Whether to plant or float, that is the question.
The ability of hornwort to get fixed in the substrate has previously been discussed. In certain cases, it is preferable to just let it to float on the surface of the water. Which, however, is the most effective method?
What you choose to do with your aquascaping is mostly determined by the aesthetic you are striving for as well as the preferences of the fish.
The structures, whether planted or floated, provide excellent protection for tiny fish and are used by many species to breed and protect their young.
The fish you have in your possession must now be considered. The floating hornwort would be appreciated by surface-dwelling fish (such as hatchetfish), but the planted hornwort would be preferred by fish in the mid to lower levels of the water column (such as tetras or loach).
The use of floating plants in the lower levels of the structure provides additional protection. In addition, it provides fish with a place to go away from the sun, which helps bring out their vibrant colors.
When not displaying the vibrant colors of the fish below, floating it on the surface of the water provides an attractive aesthetic to an area that is otherwise uninteresting.
To prevent plant debris from getting into the filter, avoid growing it near the intake so that it doesn’t become clogged. Because hornwort does not have roots, it may be grown in a variety of soil types, however, fine-grained sands are preferred for securing the stem’s lower leaves.
Upkeep and consideration
A well-known characteristic of this plant is its ability to grow very fast. The pace of growth is difficult to predict since it is reliant on a multitude of conditions, although it is not unusual for it to grow 5 or more inches in a single week.
Make sure that the plant receives a high intensity of light in order to accelerate its development. By switching out the light fixture and ensuring sure nothing is blocking the hornwort, this may be accomplished. Plants grow bigger and greener as a consequence of more light.
When compared to a brighter tank, a hotter tank has the same impact. Take special care to consider the consequences of adjusting the temperature on any other organisms that may be present in your tank while making this decision.
Hornwort should get ample nutrition from a well-maintained tank; but, if it is competing with other plants for resources, adding nutritional supplements once a week may help to accelerate the plant’s development.
It must be maintained after it has reached the appropriate length. This entails keeping an eye out for new development and removing the stem from the top of the plant to reduce the plant’s size to the desired level.
Whenever you see that the stems are becoming out of control, it will be necessary for you to take cuttings from time to time.
Problems that are often encountered
It is normal for it to grow to excessive size and begin to dominate the tank as a result of its fast development. This should not be a problem if you do regular maintenance and clip the stems.
Despite the fact that their huge potential size has made them attractive for ponds, their length still has to be managed in this setting.
In order to avoid hornwort from covering the tank’s surface and preventing light from reaching its bottom, it is essential to keep its growth under control at all times. Ground-based plants might be killed as a result.
Its ability to shed excessively is another prevalent issue. Hornwort may drop its needles at an alarming pace, however, this is not always the case.
Do not be concerned if you see shedding when the fish is first introduced to the tank since it is just getting acclimated to the environment.
Small levels of shedding are normal for them; but, if they are shedding in greater quantities than usual, it is possible that the temperature in your tank is too warm.
Lowering the temperature and testing the nutritional levels to verify they are within normal ranges are also options if it is safe to do so.
Hornwort (Ceratophyllum demersum) propagation Hornwort (Ceratophyllum demersum)
Knowing the plant’s widespread success in the natural, you would expect it to be simple to propagate it.
Hornwort spreads by vegetative fragmentation, which is a frequent method of propagation for invasive plant species.
This is the process through which a portion of a plant gets detached from the rest of the plant and subsequently grows to become a new plant.
The primary stem develops a number of side branches, some of which may get detached. It might be a whole stem that breaks apart, or it could be a little bit of a stem that breaks away from the top.
Buds develop at the ends of the stems throughout the fall season.
These are discharged and remain in the bottom of the tank over the winter, where they will eventually grow into new plants in the spring. However, as compared to vegetative fragmentation, this is significantly more common in captivity.
To increase the number of hornwort in your aquarium, consider cutting off a side stem and putting it somewhere, or float it somewhere else in the tank. This should begin to take shape as a new plant during the following few of weeks.
Tank Compatibility and Tank Mates
Hornwort’s compatibility with fish is not usually a major worry, since it is a nice companion for almost all fish species. Having said that, it pairs better with some types of fish than it does with others.
The majority of people will profit, but live-bearers will benefit the most. When fish such as Common Mollies or Guppies are mating, they will utilize the plant as a sanctuary for their young.
They may also be used as a food source for some fish species. Gouramis and angelfish are among the species that will consume the plant, so keep this in mind when selecting your fish.
Snails, shrimp, and scavenging fish (such as loaches) are excellent at cleaning up any debris produced by the plant, which helps to keep the bottom of the aquarium appearing cleaner.
How Do You Know If Hornwort Is Right for Your Aquarium?
Hornwort is a low-maintenance plant that is likely to thrive in your aquarium due to its low requirements. Because it is a resilient plant, it is a good choice for first-time gardeners.
It serves a number of functions, including boosting the safety of early fry while also lowering the amounts of fish waste and algae.
For surface-dwelling fish, its capacity to operate as a floating plant makes it an uncommon focus of interest, while planted alternatives offer refuge for fish at lower levels of the food chain.
They will make a lovely addition to most aquariums if you are willing to maintain them by cutting the stems on a regular basis to keep them from taking over the whole tank.
