I have a bunch of it... I leave it as a "tangle" in the original tanks & when one breaks free ( I have a lot of flow in the tanks that have Java Fern in them ) I pluck them off the filter intakes, & I keep a roll of lead free solid core solder in my tank work area, I just cut off an inch & wrap it around the little runner, between leaf shoots... just bending a "U" shape, with my fingers, & slide it over the runner & pinch it closed with my fingers & drop them into another tank that has a space for it... ( my Bichir / Silver Doller tank didn't have any foliage in it, & the Silver Dollars are known grazers ) but they seem to for the most part leave them alone, so I have many Java Fern starts in that tank... I pluck about 1 per week off my filter intakes... just dropping them in, drifting down, seems to give them all the "planting" they need...
