Marimo Moss Ball (Aegagropila linnaei)

Marimo Moss Balls are neither moss nor a true plant, but a unique species of round, velvety green algae that forms naturally in a handful of lakes worldwide — a low-maintenance, sculptural addition to any tank.

They're virtually indestructible, require no substrate or CO₂, and slowly roll around the tank floor, helping absorb excess nutrients along the way.
