Monosolenium

Monosolenium tenerum is a liverwort of Asian origin, known incorrectly in the aquarium trade as "pellia" (true Pellia species are different). It builds dense clumps of flat, dark green, semi-transparent, lobed branches. It resembles Riccia but is larger and darker; the most important difference is that it sinks in water. That is why it does not float up and break apart, and it creates a lasting green texture in the foreground or between stones. It is a good hiding and grazing area for shrimp.

It can be wedged between stones, left loose on the substrate, or tied to stone and driftwood with fine mesh. It does not attach firmly on its own; secure it in areas with flow.

• Light: Low to medium; it grows denser under medium light.
• CO₂: Not required, but speeds up growth.
• Fertilizer: Liquid fertilizer is enough.
• When the clump gets thick, the lower parts can turn brown; divide it into pieces and thin it out. The separated pieces form new clumps.
