Micranthemum callitrichoides ‘Cuba’
One of the smallest flowering plants in the aquarium hobby in foreground settings. A very beautiful carpet forming plant under optimum light and fertilization. CO2 injection is very much needed for its prostrate growth in the form of carpet. The creeping stem bears minute oppositely arranged leaves which are few millimetres wide and long. These leaves accumulate oxygen pearls underneath which brings about the detachment of plants from the substrate due to the buoyancy. So trimming is often performed to avoid this issue.
