Water wisteria can be allowed to float at the surface, and supposedly grows rather quickly with enough light. Java ferns should not be planted into the substrate, but tied to something (like a rock, or some driftwood, even a suction cup).
Don't confuse peacock moss (which is aquatic) with peacock fern (which is not). A lot of stores are selling peacock fern as an aquatic plant, and it will rot in an aquarium.
