Tanks seem to thrive better the less you put your hands in them

Couldn't agree more. My tank is full of activity, very fun to watch. My recipe for a happy, active reef is pretty simple:
1) Keep your hands out of the tank unless it's absolutely necessary. Use a magnet cleaner for glass, glue nori clips onto magnets so you can raise them out of the water without getting your hand wet, and don't mess with rock/critters inside the tank. If you must put a hand in the water, be fast and wear gloves (oils and other substances from our skin aren't good for reefs). Rearranging your rockwork may be your idea of a fun Saturday afternoon, but I can assure you your fish don't feel the same way!
2) Make sure all inhabitants -- fish and inverts -- are compatible with one another. If you have a bully present, remove him/her so the other fish can relax.
3) Keep things consistent. Don't change the aquascape around (fish get used to sleeping and hiding in certain places), keep lights on timers, feed around the same time each day, etc. Fish and corals are creatures of habit, and routine keeps them happy.
4) Maintain good water quality.
5) Make sure everyone has enough room. Crowding is stressful and leads to posturing or outright fights. Even crowded corals will compete for space, sometimes with disastrous results.
