Totally depends on your set up, I used to have a huge tank with small tree ferns growing in it, though they did out grow the tank after a couple of years, though it had good plant lights, undergravel filtration system ( a godsend for the ultimate frog tank).. If you are just using a small tank, best keep it simple for regular cleaning, as mentioned, Devils Ivy is great, needs no soil ect, just through a sprig in the tank and watch it grow.
