11Bamboo

No worries, though most people know bamboo to be a very…large…plant, bamboo also comes in dwarf varieties that are perfect for smaller ripariums on fish tanks. Grown in a riparium planter at the top of a fish tank, bamboo does well in leca, which will make the maintenance of your plant a lot cleaner and easier, while also allowing the bamboo full access to the nutrients in the water column of your Walstad Method fish tank. 

Your bamboo plants will also appreciate the additional humidity created by the water evaporating from fish aquarium, which it will need to grow properly and thrive.
