Description
Baby Tears – Micranthemum umbrosum
Introduction
Baby Tears (Micranthemum umbrosum) is a delicate and attractive aquatic plant renowned for its small, round leaves and lush, carpeting growth. This plant is native to the Americas, flourishing in slow-moving rivers and wetlands. Its bright green appearance makes it a stunning choice for aquascapes, whether as a foreground carpet or as a cascading midground plant. With moderate care requirements, Baby Tears is a favorite among aquarists seeking a natural and vibrant aquarium aesthetic.
1. Natural Habitat and Characteristics
Baby Tears thrive in tropical and subtropical regions, particularly in shaded, humid environments. In the wild, it grows partially submerged or fully emersed, forming dense mats along riverbanks and in shallow waters. Its fast-growing nature and ability to form dense carpets make it an ideal plant for aquariums mimicking natural biotopes.
2. Aquarium Setup
- Tank Size: Suitable for tanks 5 gallons and up, but larger tanks allow for fuller displays.
- Substrate: Prefers fine-grain, nutrient-rich substrates to anchor its fine roots and encourage healthy growth.
- Lighting: Requires moderate to high lighting (PAR 40–80). High light promotes compact and vibrant growth.
- CO₂ and Fertilization: CO₂ supplementation is highly recommended for dense carpets. Regular liquid fertilization ensures healthy foliage and vigorous growth.
- Water Parameters:
- Temperature: 68–78°F (20–26°C)
- pH: 5.5–7.5
- Hardness: Soft to moderate (1–10 dGH)
- Placement: Ideal for foreground carpeting or as a midground bush when grown vertically.
3. Care and Maintenance
Baby Tears require consistent trimming to maintain their shape and density. Left unchecked, they can grow upward instead of forming a low carpet. Propagation is simple—cut sections of the plant and replant them in the substrate to expand coverage. Ensure good water circulation and a stable environment to avoid algae growth.
4. Compatibility with Tank Inhabitants
This plant is compatible with most peaceful fish and invertebrates. Shrimp, such as Amano and Cherry Shrimp, thrive among its dense leaves, while small fish like Tetras and Rasboras enjoy swimming through its greenery. Avoid larger herbivorous fish like goldfish or certain cichlids, as they may uproot or damage the plant.
5. Common Challenges and Tips
- Melting Leaves: Baby Tears may experience initial melting when introduced to new tanks. Provide stable water conditions to promote regrowth.
- Algae Growth: High light and nutrients can encourage algae; ensure proper CO₂ levels and add algae eaters like Otocinclus or Amano Shrimp.
- Leggy Growth: Insufficient light can cause the plant to grow tall and sparse. Increase light intensity for a compact carpet.
Conclusion
Baby Tears is a versatile and beautiful plant that adds a vibrant, natural look to freshwater aquariums. With its fine leaves and dense growth, it creates a lush underwater landscape when provided with proper care. Whether used as a foreground carpet or a midground accent, this plant is a must-have for aquascaping enthusiasts.
