Are crypt lucens (Cryptocoryne x willisii Lucens) easy or difficult plants to take care of?
Also, would Watersprite (Ceratopteris thalictroides) be a an easy plant to care for?
I have kept both plants before, and have not had trouble with them. Both were grown successfully in low-light, no CO2 or higher light with added CO2. As long as you have the minimum amount of light depending on the size of your tank, both plants should do well with minimum care. The Crypt should be planted with its roots in the substrate. I have grown the watersprite both free floating and anchored to the substrate. Watersprite grows in a similar fashion to java fern, in that it has a rhizome. It is a type of aquatic fern.
