MaintenancePeriodical water changes and removal of algae are very much necessary for the better growth of Lilaeopsis brasiliensis plant. The plants can be trimmed. But they need to be removed from the substrate, separated into clusters, and then replanted. Direct trimming can cause decay. The roots if trimmed will result in faster growth and flourishing.
Planting MethodsLilaeopsis brasiliensis have very delicate and fragile roots because of which it needs to be carefully planted using aquarium tweezers. This will avoid damaging the roots. The blades of the plant should not be planted in a single clump. The best way to plant them would be to make a hole in the substrate using the tweezers and then plant the clumps. The water current in the aquarium will need to be switched off until the roots get a hold of the substrate.
Ideal SetupThe plants require the nutrient-rich substrates to grow. They can be grown in an aquarium as a foreground plant emerged or submerged in water. It can also grow in gravel or sand if sufficient fertilizers are added to the substrate.
Care LevelMedium level care is required for Lilaeopsis brasiliensis plant.
SupplementsFertilizers in the form of tablets of liquids can be added. The tablet form helps in targeting the root area. The excreta of the fish serve as a fertilizer.
LightingLED lights, T5 or T8 fluorescent lights or 5000 to 7000 Kelvin full spectrum bulbs can be used. The lighting should reach the bottom of the aquarium where the Micro Sword grows and it should cover 3 watts per gallon.
Water temperatureLilaeopsis brasiliensis plant’s origin is in a tropical region and therefore the temperature needs to be maintained between 72-85°F (22-29°C). The pH levels can be between 5.0 to 7.5 which is considered to be slightly alkaline or soft to moderately hard water.
PropagationThe mature plant produces runners which look like smaller versions of the mother plant. When the runners reach a height of at least half of the mother plant, they can be removed and planted in the substrate carefully. Care should be taken so that the roots do not get damaged and also each clump should have three to four leaflets. Natural propagation also happens when the plant is left undisturbed. However, pinching and planting the runners can help in creating the desired effect.
Approx. CostThe plant is available for a price range of 4 US dollars to 6 US dollars.
Common DiseasesThe yellow coloration of the leaves can be caused because of excessive lighting conditions. It can also result in algae formation which can cause contamination.
