What Is a Moss Aquarium?

A moss aquarium is an aquarium where aquatic moss is the main plant feature. Mosses grow attached to surfaces such as rocks, driftwood, mesh, or decorations rather than rooting into substrate. They form dense green carpets, cushions, or tree-like shapes that resemble underwater forests.

Moss aquariums can be:

• Shrimp tanks
• Fry tanks
• Natural aquascapes
• Low-tech planted aquariums

Because moss grows slowly and requires minimal care, moss aquariums are ideal for beginners and professionals alike.
