NOTE: THESE ARE MY 5 steps to happy fish keeping - individual results may vary. I've kept fish for going on 40 years, and this is what i've learned, but by no means do i know everything, in fact i'm positive that you know more than i do in many areas.
In order of importance (and really #1 is the most important by far):
1. Overfilter. Look, i'm no scientist, but if there is one thing I do know is that i love filtration. Over filtration. My motto? Fit as much filtration on any one given tank as you can - the only limit being physical space and money (initial cost and electricity). I don't know if there is law of diminishing returns at work, but frankly I don't give a crickets butt in a chicken coop. What I know for sure, is that by over filtering, i've covered my butt when it comes to mistakes and water change lapses and overstocking.
2. Water changes - make them and make them often.
3. Pay particular attention to diet, not yours, the fishes. Don't over feed.
4. Start with good stock, and group them with some common sense.
5. Heat - keeping my charges at a few degrees above suggested the value keeps their systems running in tip top shape.
