Lilaeopsis Brasiliensis Care

Lilaeopsis Brasiliensis care entails some basic needs. Here are a few of them:

– Substrate and Nutrient

Plant the Lilaeopsis Brasiliensis in nutrient-filled soils like iron-enriched clay soil or aquarium soil. These plants can also grow in gravel or sand, it would need more nutrients via Co2 and liquid or tablet fertilizers. We recommend tablet fertilizers because they efficiently target the plant’s roots. In addition, fish wastes are also beneficial as they provide nutrients to aquarium plants.

– Filtration System

The Lilaeopsis Brasiliensis needs a steady water current to prevent algae growth and promote healthy plants. Therefore, perform regular water changes and routine tank cleaning to prevent contamination.

– Tank Mate

The delicate Lilaeopsis Brasiliensis plant would not withstand large-sized aggressive fish. These species have tendencies to uproot the plants from the soil. On another note, herbivorous fish would do more harm than good.

Hence, tank mates to avoid are Oscar, goldfish, Jack Dempsey, and cichlids. However, the Lilaeopsis Brasiliensis would get along with the most peaceful small-sized fish.

– Lighting

The Lilaeopsis Brasiliensis enjoy direct, bright, and intense lighting, it would be ideal to make sure the other plants do not cast a shadow on the Lilaeopsis Brasiliensis plant. The light it receives initiates the photosynthesis process causing it to grow rapidly. However, the Lilaeopsis Brasiliensis growth rate would decline significantly in a poorly lit tank.

Hence to obtain the lawn effect, install 5000 to 7000 Kelvin full spectrum bulbs. Similarly, you can opt to use the T5/T8 fluorescent lights for your aquarium setup. If you are using the guide three-watt per gallon, bright LED lights are another good option. Nonetheless, the lights should reach every part of the tank you planted the Lilaeopsis Brasiliensis.

– Tank Size

Caring for Lilaeopsis Brasiliensis   includes keeping them in a conducive tank. The minimum recommended tank size for the Lilaeopsis Brasiliensis is 10 gallons.

– Lilaeopsis Brasiliensis Temperature and Ph

The Lilaeopsis Brasiliensis is original from tropical waters in Brazil and other parts of South America. The latter is the reason why the temperature range of 72 85F is adequate. Nonetheless, the pH levels in the Lilaeopsis Brasiliensis tank should be maintained between 5.0 to 7.5.

They thrive in mildly alkaline and soft to moderate water. Please note that extreme alkaline enclosures are detrimental to the Lilaeopsis Brasiliensis health.


– Origin

Lilaeopsis Brasiliensis is also known as Micro Sword, Micro Sword Plant, Brazilian Micro Sword, Micro Sword Grass, Carpet grass, or Copra grass. It is originally from Brazil but is now commonly used in other countries. The name “Lilaeopsis” translates to ‘charming the eye’ while “Brasiliensis” refers to the plants’ native habitat, Brazil. Furthermore, the Lilaeopsis Brasiliensis size is micro, hence its compact size.

– Description

Lilaeopsis Brasiliensis is a green grass-like plant with flat leaves. The leaves of this plant sprout from tiny branches and are slightly wider in the middle but have pointy tips.

– Lilaeopsis Brasiliensis Growth Rate

The Lilaeopsis Brasiliensis plant growth rate is slow while in captivity. They can attain an average height of three inches in a tank but for growing up to seven inches in their natural habitat.

However, with the adequate enclosure parameters, they will likely take months to cover their tank completely.

How to Plant the Lilaeopsis Brasiliensis

Planting the Lilaeopsis Brasiliensis is easy, but you need to take special care not to damage its fragile roots. You may use tweezers to prevent this and dig the substrate before planting. However, do not plant all the plant blades in one clump.

Once you have planted, wait for some days for the roots to take hold of the substrate. Turn off the tank filter during this time so the plant does not get washed away by the water current.


Under different light settings, the Lilaeopsis Brasiliensis plant is either light or deep green. It is likely unhealthy if the plant begins to exhibit any other color contrary to these. Here’s what could be wrong:

  • The tank lighting is inadequate
  • The plant is not getting enough nutrients

Excessive lighting in the Lilaeopsis Brasiliensis tank has some adverse effects. As it encourages the plant’s growth, it also causes algae growth! But, do not worry as you can introduce algae-eating aquatic animals like the bristle nose pleco, Amano shrimp, and Nerite snails. These trios get along and will not harm the Lilaeopsis Brasiliensis plant.


You can propagate Lilaeopsis Brasiliensis via these two methods:

– Runners

Lilaeopsis Brasiliensis reproduces from its base through runners. Runners are baby plants that would mature with time into separate plants. When they grow to half the height of the main plant, you may detach and replant them. The new runners would also produce more, and the cycle continues.

On the other hand, the propagation process would also take place without external input. The plant would even create a carpet and spread out. But, we recommend you accelerate the process by separating and replanting.

– Cutting

Another method to follow while propagating the Lilaeopsis Brasiliensis is the cutting technique. Cut out a clump of Lilaeopsis Brasiliensis plant from your tank. Then divide it into plantlets so each runner would contain about five leaves each.

Choose the tank area you wish to propagate the Lilaeopsis Brasiliensis on. Then plant each plantlet but space them out as they would need it. After a while, they would produce roots and leaves.


– Aquascape

The Liliaeopsis Brasiliensis would beautify and cover your tank’s ground. They form compact carpets that are eye-catching.

– Removal of Excess Nutrients

The Lilaeopsis Brasiliensis can absorb harmful chemicals like copper and lead, as these heavy metals are toxic to aquatic animals.

– Foraging Place

The Liliaeopsis Brasiliensis plant can be used by crustaceans for foraging. In addition, it can be used in growing biofilm, which is an excellent first meal for fry and baby shrimps.

– Oxygenation

The Liliaeopsis Brasiliensis plant gives off oxygen which is beneficial to aquarium fish.

– Curbs Gas Pockets

Liliaeopsis Brasiliensis root system hinders the production of anaerobic pockets that may form in their substrate.

– Shelter

The Liliaeopsis Brasiliensis plant is a great hiding place for smaller fish from predators. Nonetheless, some fish use the plant as a spawning surface.


Is the Liliaeopsis Brasiliensis Beginner Friendly?

No, it is not. A novice hobbyist who plants the Liliaeopsis Brasiliensis without basic information would struggle. This is primarily because the plant grows slowly. In addition, when this compact plant is pruned incorrectly, it could begin to die

Does the Lilaeopsis Brasiliensis Require Co2 Injection To Grow?

Yes, they do! Sufficient levels of Co2 are essential for photosynthesis in the Lilaeopsis Brasiliensis tank. Hence, we recommend Co2 injections even though the Lilaeopsis Brasiliensis will grow without them. In reality, plant growth will be very slow.

Co2 Dosage Recommendation and Benefits

We recommend about 15 milligrams per liter of Co2 injection in the Lilaeopsis Brasiliensis    tank. It will speed up the plant growth rate, particularly if you plan to cover your tank with the Lilaeopsis Brasiliensis carpet in a few months. In addition, the Co2 targets the plant’s shoot, effecting a denser, vibrant, and healthier look. Keep in mind, the tank lighting must be monitored to control the plant Co2 absorption rates.

Hence, douse the plant regularly with Co2, particularly during the day. You can use a diffuser, canister, and regulator to dispense and monitor the dose. Set the rates to 1:2 Co2 bubbles per second.

How To Create the Lawn Effect With the Lilaeopsis Brasiliensis Plant?

The lawn effect is easy to create using the Lilaeopsis Brasiliensis plant. All you need to do is plant the Lilaeopsis Brasiliensis baby plants in diagonal rows like a chessboard. Place them two inches apart, but they do not need to be buried deep into the substrate.

On another note, before planting the Lilaeopsis Brasiliensis, trim the roots of the plantlets carefully. This would help the plant take root and grow faster.

Other Similar Species That Is Suitable for the Lawn-Effect

1) Liliaeopsis Mauritiana

The Liliaeopsis Mauritiana is another species that is adequate as a lawn-forming plant. They have similar features to the Liliaeopsis Brasiliensis. On another note, this plant grows taller and is commonly used in bigger tanks, where their leaves are thinner and smaller.

The Liliaeopsis Mauritiana requires less lighting than the Liliaeopsis Brasiliensis. Unlike the Liliaeopsis Brasiliensis, which requires three-watt per gallon, the Liliaeopsis Mauritiana needs only 1.92 watts per gallon. They also thrive at a similar temperature as the Liliaeopsis Brasiliensis and are planted the same way.

2) How To Trim the Lilaeopsis Brasiliensis Plant?

Trimming the Lilaeopsis Brasiliensis helps to keep the plant aesthetically pleasing. Use sharp scissors to prune the clumps. But, you should not trim straight along the tops as that could cause decaying. Rather separate the plantlet and gently cut them.

Where To Buy the Liliaeopsis Brasiliensis?

The Liliaeopsis Brasiliensis is commonly sold in aquatic nurseries and local fish stores. Depending on the vendor and quantity, they would generally cost about four to eight USD. Additionally, the plant may come in a pot or be densely packed in cloth. Similarly, you can buy them from online distributors.

What To Look Out for When Purchasing the Liliaeopsis Brasiliensis Plant?

While purchasing the Liliaeopsis Brasiliensis, you must pay heed to these key points:

  • Choose a Liliaeopsis Brasiliensis plant with a vibrant green color
  • The Liliaeopsis Brasiliensis leaves must be at least 2 inches long
  • There must be no algae on the plant
  • The Liliaeopsis Brasiliensis leaves must not show any signs of yellowing
  • Check that plants’ roots are densely packed
  • Confirm that the roots are white

Note that you may have to purchase the Liliaeopsis Brasiliensis as an emersed plant. This means that the Liliaeopsis Brasiliensis plant would have to transition and grow as a submersed plant in your tank. The transitioning would likely cause the plant to lose all its leaves. However, it would recover and grow back in a few days.


Lilaeopsis brasiliensisThe fact that the Liliaeopsis Brasiliensis is slow-growing is advantageous. This suggests less maintenance as you would not need to trim it often. Here’s why we like the Lilaeopsis Brasiliensis plant:

  • It has beautiful grass-like features
  • It can be planted to create a lawn effect in a tank
  • It can grow in or out of water

Keep in mind that they would propagate easily if you followed the right techniques. Hence, add some Liliaeopsis Brasiliensis runners to your enclosure and watch it grow into a lush carpet!
