Pellia

Monosolenium tenerum (Pellia) is a thalloid liverwort producing broad, flat, emerald-green lobed fronds that carpet the foreground or drape naturally over rocks and driftwood. Unlike true mosses, it does not attach via rhizoids—instead it can be weighted between rocks or attached with thread, creating attractive cascading drapes over hardscape. One of the easiest and most tolerant of the 'moss-type' plants for planted aquariums.

Wedge between rocks or attach with thread or glue. Provide low to medium light. CO2 is not required but improves growth rate and density. Gently brush off any debris that accumulates on the flat fronds. Propagate by dividing the thallus.
