yea i keep a good deal in mine, that stuff just wont die.
i also have 2 species of java fern and a banna plant that have been doing well for about a month, and still look good.
i have a water sprite that i was just experimenting with, and thought it to be dying. however i was looking at it last night, and the majority of the plant is deterirating, except one part on the very top. this section of the plant is on the very tip, and has turned a deep florecent green, and sprouted roots. my guess is that the salinity caused the plant to change, and all the nutrients have been focused into this sprout.
i am hoping that with a little more time, that section grows and breaks off and will be able to tolorate the salinity.
