cichlids and plants

I have a question on cichlids and plants.  Most of the plants that we 
keep in our aquaria are soft water loving.  How can you keep cichlids 
like Juliochromis (my favorite) from the hard-water lakes of eastern 
Africa, with plants that are by far the softest-water loving thing 

Another question I have is the on the natural habitat of Anubius.  Are 
they normally found emmersed or immersed?  Their anatomical structure 
screams out "emmersed"...so what is the deal??  Another Dracena that 
fell into someone's tank and survived???
