For myself, I have to say I choose plants because I like the way they look, or think they would look good in my tank(s). Some consideration, of course, is given to their growth habits. For example, I would love to try some Eriocaulon, but with kh over 9, and gh around 12, that would be foolish. I also don't want something I have to prune twice a week.
