Cryptocoryne Wendtii: Basic information

Cryptocoryne wendtii is a well-known and widely available aquatic plant in the aquarium hobby. It comes in several colour variations, including green, red and brown. The size of the leaves, as well as their texture, can vary greatly from specimen to specimen. Its amazingly patterned growth and leaves have gained it a lot of popularity among hobbyists.

Because the plant does not grow to be very large, it is ideal for small aquariums. It preferentially grows well in hard water, as do other Cryptocoryne wendtii of Sri Lankan origin. It is also possible to grow Cryptocoryne wendtii emersed, as it is a root feeder and does well in pots.

Cryptocoryne Wendtii Care

Cryptocoryne wendtii care is an extremely difficult task, as it requires certain water conditions. However, it is an excellent plant for both experienced and novice aquarists because, while it is not simple to grow, it can be placed into stunning displays and give an outstanding look to any aquarium setup.

It must be planted directly into the substrate, where it develops deep roots, making it difficult to uproot. This makes Cryptocoryne wendtii excellent for those looking for a plant that can withstand the attention of notorious diggers, such as cichlids and loaches.

It should be fertilised on a regular basis, and Seachem Flourish Trace should be added at the very least after weekly water changes.

Cryptocoryne wendtii thrives in low-light environments. Be careful, as other plants may crowd it out in aquariums with high levels of lighting due to its slow growth. To simulate full spectrum lighting, use a T5 or T8 fluorescent bulb when selecting lighting. LED lights have been used successfully by some aquarists in recent years, so they may also be a good choice for growing Cryptocoryne wendtii.

– Introducing Cryptocoryne Wendtii to Your Setup

It is common to see a significant leaf die off when first introducing Cryptocoryne wendtii to an aquarium. Many of the leaves will wither away quickly, but this does not mean the plant is dead.

This is a common occurrence caused by a sudden change in the plant’s water conditions. The plant’s roots should remain healthy, and new leaves should appear soon. Do not lose patience, as in certain instances this will take a while.

Cryptocoryne Wendtii: Propagation

It is easy to propagate Cryptocoryne wendtii. All you have to do is remove a small portion of the root with some stem attached. This can then be planted in the substrate and will grow into a new plant over time.

One common practise is to pull mature plants apart, resulting in a plethora of new plants that can then be distributed throughout the aquarium or sold to others.

Cryptocoryne Wendtii: Tank Maintenance

– Tank Parameters

This plant is adaptable to a wide range of environmental conditions. Cryptocoryne wendtii prefers neutral water pH but will grow in conditions ranging from weakly acidic to alkaline. This species grows well in hard water, but can also be grown in soft water.

Water temperatures ranging from 68 to 82 F are ideal, making these plants suitable for both cool water and tropical freshwater fish tanks.

– Water Quality

This plant prefers clean water with consistent parameters. One of the most effective and important ways to maintain good water quality is through regular partial water changes.

Aspects such as the source of the water you provide must also be taken into account. Plants like Cryptocoryne wendtii can struggle with hard water. If your source water is extremely hard, you should think about installing a RO system.

The frequency and volume of your water changes will vary according to the size and density of your aquarium. A 15 to 20 percent water change once a week is recommended in lightly stocked aquariums with good filtration.

Testing your water conditions on a regular basis is an important part of monitoring the health of your aquarium. Fortunately, using a liquid or strip test kit makes this relatively simple. Use your test kit to monitor ammonia, nitrites, and nitrates, as well as pH and hardness. A thermometer is also required to monitor the efficiency of your heater.

– Filtration

Another important aspect of maintaining good water quality in planted aquariums is adequate filtration. Contrary to popular belief, filters are not only used to remove physical particles from water, but they are also required for the biological filtration process.

Beneficial bacteria convert harmful chemicals from fish waste and food into less harmful compounds during this process. To keep your bacteria colonies safe, never clean your filter media with anything other than tank water and never replace all of your filter media at once.

Plants such as Cryptocoryne wendtii, produce more ammonia than fish in a planted tank setup, due to leaf droppings. It is critical to invest in a high-quality filtration unit, such as a canister filter, to keep algae outbreaks at bay in your aquarium.

– Flow

As this plant is best suited to slow-moving rivers and streams, it will thrive in aquariums with low to moderate flow. If necessary, the aquarist can use hardscape features such as rocks, driftwood, or ornaments to break up the water flow in the aquarium.

– Cryptocoryne Wendtii: CO2 Injection

Growing this hardy plant species does not necessitate the use of CO2. However, if you already have a planted aquarium with CO2, you can grow this plant in the same system and it will benefit them to some extent

A regular dose of a liquid carbon supplement, such as Seachem Excel, is a useful alternative to CO2 injection that could enhance the growth of these aquarium plants.

– Cryptocoryne Wendtii: Substrate

Proper substrate is required for the successful cultivation of Cryptocorynes. These plants grow in the wild on a variety of soils, ranging from sludge deposits to pebbles of various sizes. Quite often, the bottom of these rivers is covered with a thick layer of leaf debris of varying degrees of decomposition.

It is recommended that non-fatty clay and compound fertilisers — like tablets containing microelements and ferrum chelate that is digestible for plants — be added to the bottom substrate of a tank where your Cryptocoryne grows.

The majority of Cryptocoryne species have a dense, long, and branchy root system. As a result, the recommended thickness of the bottom substrate layer is 2.4 – 3.1 inches. With such substrate thickness, you must take additional precautions to prevent the formation of anaerobic zones.

– Cryptocoryne Wendtii: Temperature

Temperature in the environment is an important factor for Cryptocoryne plants. Cryptocoryne wendtii temperature ranges from 73 to 79 F (23 to 26 C). At that point, maintaining stable temperature conditions with minimal differences between night and day temperature values is critical.

This task is easily accomplished by using a heater with a thermostatic switch. Most species stop growing at water temperatures lower than 273 F, and prolonged exposure to even lower temperatures usually results in plant death.

– Cryptocoryne Wendtii: Water Level

The height of the water level is critical for successful cryptocorynes cultivation in a tank. As Cryptocoryne wendtii size is medium, the depth for water is considered to be between 7.8 and 11.8 inches (measured from the substrate to the water surface). Cryptocorynes exhibit brighter colouring in such heights of water than in high tanks completely filled with water.

A tank 39 to 47 inches long and 12.5 – 19.5 inches high is ideal for cultivation. This is due to the fact that most Cryptocoryne wendtii have a more ornamental appearance when planted in a large group, which is difficult to achieve in a short and narrow tank.

How To Set Up Your Aquarium Tank for Cryptocoryne Wendtii

These popular aquarium plants are hardy and adaptable, so they will thrive in the majority of freshwater aquarium setups. These cryptocoryne Wendtii can even be kept in small aquariums as small as a few gallons, depending on the variety.

Remember that the smaller your setup, the more difficult it is to maintain stable water conditions because parameters can change quickly.

The key is to provide enough open space and substrate at the tank’s bottom for them to grow a strong set of roots. Ideally, 2 – 3 inches of aquarium soil, sand, or gravel should be provided.


Cryptocoryne wendtii is a plant that all aquarists should think about cultivating. This high-maintenance species has a wide range of aquascaping applications and will thrive in a variety of lighting conditions. Following are some important points related to this plant:

  • The plant has a medium height, making it ideal for small tanks as it doesn’t grow to be too large.
  • The plant can easily survive in slightly basic or acidic water, but it will struggle in very hard water.
  • It doesn’t need CO2 injections.
  • The light requirements of this plant are low.
  • Make sure there is clean water. For this purpose, install a good filtration system, although Cryptocoryne wendtii can filter most of the harmful stuff on its own.
  • Make sure to provide open substrate to the plant.
