Crinum natansdoes have any special requirements as to water or light and it even tolerates weakly brackish water. Be sure,however, to cover only half of the bulb with a substrate poor in nutrients and decomposing organic compounds - if the bulb is covered completely it will going to rot. Crinum natans it is only suitable for large aquaria whereit proves to be a graceful solitary plant. It is a slow growing plant but once it has attained its full size the wavy leaves will float on the surface - 'natans' means floating! The plant is less light demanding and hasbroader leaves than Crinum calamistratum. Older individuals willingly set adventitious bulbs, and these new bulbs are the easiest way of propagating the plant though propagation from seeds is quite easy, too. Crinum natans is 'cichlid-safe' plant because the fish do not like the very sturdy fibres of the leaves. See also fish-proof plants from Tropica Aquarium Plants. Author: Tropica
