Scientific Name: Micranthemum tweediei 'Monte Carlo'
Common Name: Monte Carlo
Origin: Argentina
Growth Rate: Moderate to Fast
Difficulty Level: Easy to Moderate
Temperature: 20–28°C
pH: 5.5–7.5
GH: 1–12 dGH
KH: 0–8 dKH
Moderate to high lighting is recommended.
Strong lighting encourages dense, compact carpeting growth.
Under lower light conditions, the plant may grow more vertically and produce a less compact carpet.
CO₂ supplementation is recommended for optimal growth.
Promotes faster spreading, denser carpets, and healthier foliage.
Can grow without CO₂, making it suitable for some low-tech aquariums, though growth will be slower.
Requires a consistent supply of macro and micronutrients.
Benefits from nutrient-rich substrates and regular fertilization.
Adequate nitrate, phosphate, potassium, and trace elements support vigorous growth.
Stable nutrient levels help maintain a lush, healthy carpet.
Best suited for the foreground.
Commonly used as a carpeting plant.
Creates a vibrant green, natural-looking carpet across the aquarium floor.
Propagated through runners and stem fragmentation.
Small portions can be replanted to establish new growth areas.
Spreads horizontally and gradually covers the substrate under favorable conditions.
Plant in small portions with spacing to encourage even carpet formation.
Trim regularly to maintain a low, dense growth habit.
Ensure adequate water circulation to prevent debris accumulation within the carpet.
Stable lighting, nutrients, and CO₂ will help prevent algae issues and promote healthy growth.
Micranthemum tweediei 'Monte Carlo' is one of the most popular carpeting plants in the aquascaping hobby, valued for its small, bright green leaves and creeping growth habit. It forms a dense, attractive carpet that adds depth and a natural appearance to planted aquariums. Easier to maintain than many other carpeting species, it is widely used in Nature, Iwagumi, and contemporary aquascapes. When provided with proper lighting, nutrients, and CO₂, it creates a lush foreground that beautifully complements rocks, driftwood, and larger aquatic plants.
