🌿 Overview

Micranthemum umbrosum is a creeping freshwater plant from South America. Known for its small, round leaves and carpet-forming growth, it is a favorite for nature-style aquascapes, nano tanks, and planted community aquariums.

While it is beginner-friendly, CO₂ supplementation and high-intensity lighting promote faster growth, compact leaf clusters, and healthier carpets. It adapts to moderate light, but carpets will grow slower and may require more maintenance.

🍃 Appearance

• Tiny, round bright green leaves forming dense, lush carpets
• Height: 1–3 cm
• Creeping stems allow rapid horizontal spread
• Ideal for foreground planting
• Adds texture, depth, and a natural lush look to aquascapes

🌿 Plant Type (Hard/Soft)

• Type: Creeping / carpeting plant
• Category: Soft aquatic plant
• Growth rate: Moderate, faster under CO₂ and high light

🌡️ Ideal Water Temperature

• 20°C – 26°C (68°F – 79°F)
• Prefers stable tropical freshwater conditions

💡 Lighting Conditions

• Moderate to high lighting recommended
• High light ensures compact, dense carpets
• Low light slows growth and elongates leaves

🌿 CO₂ Requirement

• Optional but recommended
• CO₂ promotes faster spreading, dense carpets, and vibrant green leaves
• Can survive without CO₂ but growth is slower and less dense

⚗️ Ideal pH Level

• pH: 6.0 – 7.5
• Slightly acidic to neutral water preferred

💧 Other Requirements

• Substrate: Fine-grained, nutrient-rich substrate for strong rooting and uniform carpet formation
• Fertilization: Benefits from liquid fertilizers and root tabs
• Water hardness: Soft to moderately hard
• Regular trimming promotes lateral growth and compact mats
• Prefers stable water conditions for best results

🌱 Propagation

• Propagates via creeping stems / runners
• Lateral shoots spread quickly under optimal light and nutrient conditions
• Can be divided to expand coverage across the substrate

💡 Do You Know?

Micranthemum umbrosum is highly valued in aquascaping for its delicate, bright green carpets. Its small leaves create a miniature grass-like effect in foregrounds, making it ideal for nature-style aquariums, high-tech aquascapes, and nano tanks.
