Pothos love to grow in water -- they even grow with no added fertilizer
or nitrates, just plain water. If you have a friend with a pothos plant,
get tip cuttings (4-6 inches), tie together and suspend directly in
your tank. They even grow in low or no natural light. If light is a
problem, look for over low light plants that like moisture. Just remove
them from their pots, and rinse all soil off the roots before suspending
in the tank (you can cover the roots with a mesh bag or even a sock).
