I may mess around / experiment by buying one plant and see how it goes.
How would I know when to trim at the bottom or the top?
I answered that, you go by the appearance. When the stem plant reaches the surface, it is time to trim it. In a tank with sufficient nutrients and light, usually once every two weeks for Pennywort, sometimes every week. I have it in my 90g and this schedule usually works.
If plants don't grow, they start dying, and that pollutes the tank. Anubias is fairly hardy, but it needs food. Nutrients are food for plants; you can't live without food, neither can plants.
