Riccia fluitans ( 5x5cm)

Riccia fluitans is a floating bladderwort which is actually a very easy plant to grow.  As a floating plant, moderate lighting is sufficient for good growth and CO2 injection is unnecessary. It can be tied to wood or stone and placed anywhere in an aquarium.

Its requirements for light(3+wpg) and CO2(30ppm) are high when grown attached to objects in the aquarium. It also appreciates rich fertilization through the water column, including nitrate, phosphate, potassium, and iron.
