Answers: I usually switch the water every two or three days. They are not that picky. Just don't tolerate the water carry gross.
My first instinct is to tell you to put it within some nice potting soil but if it's doing well within water I would read aloud when the water starts to turn color or when the marine starts to smell a little bit.
