🌿 Overview

HC Cuba is a creeping, soft aquatic plant native to Cuba and South America. It has become a staple for planted aquascapes due to its miniature leaves and carpet-forming growth habit, making it ideal for foreground and nano tank planting.

While it is moderately beginner-friendly, this plant performs best in high-light, CO₂-supplemented aquariums with nutrient-rich substrates. Under low-tech conditions, growth is slow and requires careful maintenance to prevent stretching.

🍃 Appearance

• Tiny, round bright green leaves forming dense, low carpets
• Height: 1–2 cm
• Creates a miniature grass-like effect in the foreground
• Perfect for nano aquariums, aquascapes, and nature-style tanks
• Adds lush texture and depth, contrasting beautifully with stem plants

🌿 Plant Type (Hard/Soft)

• Type: Creeping / carpeting plant
• Category: Soft aquatic plant
• Growth rate: Slow to moderate without CO₂, faster with CO₂ and high light

🌡️ Ideal Water Temperature

• 22°C – 28°C (72°F – 82°F)
• Prefers stable tropical freshwater conditions

💡 Lighting Conditions

• High lighting required for compact growth and vibrant green coloration
• Moderate lighting slows growth and may cause legginess
• Low light is not recommended for carpets

🌿 CO₂ Requirement

• Highly recommended
• CO₂ promotes rapid spreading, dense carpets, and healthy leaf color
• Can survive without CO₂ but growth is very slow and mats may remain sparse

⚗️ Ideal pH Level

• pH: 5.5 – 7.0
• Slightly acidic to neutral water preferred

💧 Other Requirements

• Substrate: Fine-grained, nutrient-rich substrate promotes strong rooting and uniform carpet formation
• Fertilization: Benefits from root tabs and liquid fertilizers
• Water hardness: Soft to moderately hard
• Regular trimming encourages lateral spread and prevents legginess
• Prefers stable water parameters for healthy carpet formation

🌱 Propagation

• Propagates via runners / side shoots
• New shoots spread from stolons, forming dense carpets over time
• Can be divided and replanted to cover larger areas

💡 Do You Know?

HC Cuba is one of the most iconic foreground plants in aquascaping, often used as a benchmark for high-tech planted tanks. Its ultra-small leaves create a fine, lush carpet, mimicking natural riverbeds, and making it a favorite for nano tanks and show aquariums.

🏷️ Plant Category Classification

🟢 Beginner Friendly

✔ Moderate – Can survive in low-tech setups but growth is slow and requires maintenance

🟢 Non-CO₂ Plant (Low-Tech)

✔ Limited – Can survive without CO₂, but will not form dense carpets

🟢 High-Tech Plant

✔ Yes – High light and CO₂ produce dense, vibrant, fast-growing carpets
