Stability: always make minor changes, be it water change, dosing additives or changing of light tubes etc etc
Natural Food Source: try not to keep fish that feed solely on pods / natural algae as new addition usually feed on them before accepting "prepared food"
Avoid Stress: dont rescape, frag, add new fish etc etc every other day / week
Murphy's law: try to have backup equipment, esp return pump, if possible chiller too
