I'm interested in getting plants but I was wondering it there are any plants that don't have to be put in soil? Like, maybe just floating ones, or even ones that can just be tied down to a rock. Would I need to add something to the water to help the plants thrive? If there are such plants, can I keep on adding salt and bettafix to my tank?
I just have gravel....
Also, if this helps, I don't have a filter.
I do regular WC's instead.
I've read other threads and such on plants, but I got confused....so I made me a thread just to clear this up for me.
