Habitat and Tank Conditions

Tank Size

The Monte Carlo plant can grow in tanks of different sizes, ranging from 5-gallon nano tanks to medium and large tanks. However, its growth and density can vary depending on the tank size.

Therefore, it’s important to select the right tank size to ensure healthy growth.

Water Conditions

The Monte Carlo plant can adapt to a wide range of water conditions, including temperature, pH, and water hardness. The ideal temperature for this plant is between 70-80 degrees Fahrenheit, and it can tolerate pH levels between 6.0 and 7.5. Water hardness isn’t a considerable issue since the plant is hardy and can grow well in different hardness levels.


The Monte Carlo plant needs moderate to high levels of lighting to thrive well. In general, it needs around 3-5 watts per gallon of light.

It’s important to adjust the lighting accordingly since too much or too little lighting can impact the plant’s growth.


When it comes to the substrate for the Monte Carlo plant, fine-grain substrates are ideal since they provide good support for the plant’s roots. A small-grained substrate, such as ADA Aquasoil, is an excellent option since it has the perfect grain size for the roots to grow into.


The Monte Carlo plant requires a carbon dioxide-rich environment and a liquid fertilizer to promote healthy growth. Experts recommend using a CO2 system, which can regulate the pH levels and assist the plant in absorbing nutrients.

Liquid fertilizers can help provide additional nutrients for the plant to thrive.


In conclusion, the Monte Carlo plant is an adaptable and low-maintenance aquatic carpeting plant that can enhance your foreground aquascaping. By following the proper tank conditions and providing the right habitat, you can grow and maintain healthy Monte Carlo plants within your aquarium.

Consider adding the Monte Carlo plant to your tank if you’re looking to create a natural refuge for your tank residents and add visual appeal.

Planting and Care


Before planting the Monte Carlo plant, it’s essential to quarantine it to prevent any potential contamination from unhealthy plants. It’s also recommended to divide the plants into small pieces to facilitate easy planting.

To plant the Monte Carlo plant, insert the small pieces into the substrate, making sure that it’s deep enough to provide a strong foundation for the roots. Carpet formation is the desired outcome when planting Monte Carlo plants, and to achieve this, the plants must be planted close together.

Regular trimming is necessary to prevent the plants from growing too tall and losing their carpeting effect. Additionally, trimming helps to remove any unhealthy plants, giving the healthy ones space to thrive better.

When trimming, ensure that you’re only cutting off the top portion of the plant, making sure that the base and roots remain intact.


Maintaining the Monte Carlo plant is relatively easy, provided that you have set the right tank conditions and planting arrangement. Regular trimming is one of the simplest yet most effective ways to maintain this plant.

As it grows, it can lose its carpeting effect, causing it to look unkempt. To prevent this, trim the plants regularly to encourage lateral growth and maintain short height.

When trimming, remove any unhealthy plants, such as those that have brown spots or discolored leaves. These unhealthy plants can be a source of contamination that can spread to other plants within the tank.

It’s also important to remove any trimmed pieces of the plant from the tank, as they can decay, and lead to nitrite spikes or even ammonia levels in the water. Avoid uprooting the plants when trimming to prevent the substrate from becoming disturbed.

Issues to Watch Out For


Melt is one of the common issues that aquarium owners face when planting the Monte Carlo plant. It’s seen as a yellowing of the leaves, where the plant disintegrates, and your carpeting plants start to float around the tank.

High nitrite levels can also lead to plant melting, especially when just setting up a new aquarium. To avoid melting, ensure that you follow the right tank conditions, and planting arrangement.

It’s also essential to keep an eye on nitrite spikes, especially during the first few weeks after setting up a new aquarium.

Brown Plants

Monte Carlo plants can turn brown due to insufficient light. Inadequate lighting can hinder the plant’s metabolism, causing it to wilt.

If you notice brown plants in your aquarium, increase the lighting to encourage optimal plant growth. Additionally, trimming can help stimulate growth, allowing your plant to become healthier and brighter.


Detachment occurs when the Monte Carlo plants lose their hold on the substrate and start floating around the tank. Lack of roots could be the cause; it may be due to uprooting the plants or replanting them after trimming.

If this happens, replant the plants into the substrate while ensuring they have enough roots to attach to the substrate. It’s important to avoid unnecessary disturbance of the substrate, as it can destabilize its foundation and lead to more plant detachment.


The Monte Carlo plant is a beautiful and hardy plant that can add a touch of lush greenery to your aquarium. By following the proper planting and maintenance procedures, you can successfully grow a carpet of Monte Carlo plants in your tank.

Though issues such as melting, browning, and detachment can occur, they can be managed effectively by understanding their causes and taking preventative measures.

Tank Mates

When selecting tank mates for the Monte Carlo plant, it’s essential to choose species that complement its living conditions and growth patterns. Not all fish and plants are suitable tank mates for the Monte Carlo plant, so it’s necessary to choose wisely.

Suitable Plant Mates

AR Mini, Italian Val, Rotala Indica, and Water Wisteria are suitable planting mates for the Monte Carlo plant. These plant species complement it well in terms of their adaptability to tank conditions, similar growth rates, and aesthetic appeal.

AR Mini, also known as Alternanthera reineckii ‘Mini,’ is a small stem plant that comes in a vibrant red color. It can grow up to 10cm in height and is well-suited as a background plant to highlight the Monte Carlo’s carpeting effect.

Italian Val is an ideal option if you need tall plants to contrast against the Monte Carlo’s low growth. Its narrow, elongated leaves grow tall, making it perfect for background planting.

Rotala Indica, commonly known as Indian Toothcup, is a beautiful plant that can reduce nitrate levels in the tank. Its growth rate is similar to the Monte Carlo plant, making it a complementary partner.

Finally, Water Wisteria is a versatile plant that can grow both submerged and emersed. It’s easy to maintain, making it an ideal option for those looking for low-maintenance plants.
