How to Identify Mauritius Microsword

Mauritius Microsword (Lilaeopsis mauritiana) has key botanical markers. Recognizing these features is crucial for successful aquascaping and thriving growth.

✔
Visual Shape & Growth: Compact vertical grass-like clumps forming dense green lawns over the substrate.
✔
Leaf Morphology: Slender, cylindrical bright-green leaves (approx. 2-3 inches tall) that curve slightly in the current.
✔
Root & Anchoring Structure: Stout, anchoring white roots that shoot deeply and hold tightly to the substrate.

Complete Cultivation & Spawning Guide

Follow our detailed scientific water parameters and care guides to keep your Mauritius Microsword thriving.

pH: 6.0 - 7.8, GH: 4 - 15 dGH. Adaptable to soft or moderately hard freshwater setups.

Low. Grows perfectly without CO2. Supplemental liquid carbon can be dosed occasionally to assist growth.

Moderate to high. High light intensity keeps the leaves compact and deepens the gorgeous green grass marbling.

Cut off old, yellowing, or damaged leaves at the base of the stem. Clean dead organic debris to prevent siltation.

A heavy root feeder. Requires nutrient-rich substrate. Insert root fertilizer tabs near the base every few months.

Requires deep sand or aquasoil bed (at least 2 inches) to accommodate its massive runner root network.

Optimal temperature is 18°C to 28°C (64.4°F - 82.4°F). Sensitive to severe cold shocks below 15°C.

Enjoys moderate current. Steady water flow delivers carbon and trace minerals directly to its broad foliage layers.

Its tough texture and bitter taste make it highly resistant to plant-eating fish. Safe for community setups.

Slow growth makes it susceptible to hair algae. Keep water clean and employ Amano shrimps or Nerite snails.

Best planted in the foreground. Space individual crowns 1 to 2 inches apart to allow rapid runner carpeting.

Common Diseases & Treatment

Runner Choking

Symptoms: Dense lawn layers rot at the base, turning yellow and floating away from the substrate.

Action: Caused by over-congested growth blocking water flow to the root crowns. Thin the lawn by thinning out runners every few months.

Iron Deficiency (Chlorosis)

Symptoms: New narrow leaves emerge pale green, yellow, or transparent, losing their healthy color.

Action: Dose comprehensive liquid iron or insert iron-rich root tabs near the root zone immediately.

Frequently Asked Questions

How fast does it carpet?

Under moderate to high light and rich substrate, it is a moderate grower, shooting out multiple runner stolons every week.

Can it grow in gravel?

Yes, but root runners spread much faster in fine aquasoil or soft sand than in coarse, heavy gravel beds.

How do I plant it correctly?

Use aquascaping tweezers to plant individual runners gently into the substrate, keeping the green crown base visible above soil.

Does it need CO2?

No. Lilaeopsis mauritiana is exceptionally hardy and can grow happily in low-tech setups without pressurized CO2.
