Discover the Beauty of Micranthemum Callitrichoides 'Mint Green': A Hybrid Dwarf Baby Tears
Micranthemum Callitrichoides 'Mint Green' is a rare hybrid of the popular Dwarf Baby Tears. Unlike the common variety, this plant lacks the typical deep green pigment, resulting in a much lighter green hue that has captured the attention of aquascapers.
This plant is not for the faint of heart. It's known to be extremely difficult to grow, requiring a stable environment with high lighting and CO2 supplementation to thrive. If you're looking for a challenging plant to elevate your aquascape, this is it.
Key Features
- Appearance: compact, round leaves in a soft mint green shade, offering a unique contrast in aquascapes.
- Growth Habit: grows densely, forming a lush carpet effect in the foreground.
- Size: remains small, perfect for nano aquariums or as a foreground plant in larger tanks.
- Hardiness: very delicate and requires advanced care to grow successfully.
Optimal Care
Lighting
Demands high-intensity light (60–80 PAR), 8–10 hours per day. Without strong light, its pale leaves struggle to photosynthesize properly.
Water Parameters
Thrives in stable, clean water: 68–77°F (20–25°C), pH 5.5–7.0, soft water is ideal though moderately hard water is tolerated. Excellent filtration and circulation are key to avoiding debris buildup.
CO2 and Fertilization
Requires high levels of CO2 for healthy growth — without it, the plant will not thrive. Regular liquid fertilizer rich in iron and other micronutrients helps maintain its pale green color.
Planting and Propagation
Spread evenly over the substrate in small portions to let it root; it will spread over time into a dense carpet. Propagate by cutting small sections and replanting elsewhere — patience is key given its slow growth.
Common Challenges and Solutions
Algae growth can occur due to the high light requirement — introduce algae-eating shrimp or snails and keep nutrients balanced. Melting or discoloration happens with fluctuating water parameters — maintain consistent water quality and avoid drastic changes.
Tank Mates
Pairs well with tetras, rasboras, and other small community fish; Amano, cherry, and other dwarf shrimp; nerite and other small, non-invasive snails. Avoid large, aggressive fish or those prone to uprooting delicate plants.
