I actually bought mine because I wanted the containers they were in. Then I didn't have the heart to discard the plants. I don't have any secrets.....they are in a sunny east window and when I fill up the water in the container I add a little pinch of fertilizer to the water. Looking at yours I would cut off the yellowing top down to where it is a healthy green. I also wonder what the blue coloring is at the bottom of the container?
