Nothing special going, but large water changes and did a little maintenance on the emersed land plants in the tank. I change lots of tank water every week and emersed the Chinese Evergreen in the tank water. The old water coming out of the tank is nearly the same color as the new water going in. The plants keep the water almost pure, it's pretty amazing.
By maintaining pure water conditions, my Livebearers stay healthy and live a fairly long time. The Corydoras are the real longlivers, though. The Albinos are 3 years old and the Emeralds and Bronzes are all about 6. By following an aggressive water change routine, you never have to fret over water chemistry problems, which is likely the reason for most if not all tank problems. Dissolved fish wastes never have time to foul the tank water before you remove them and the Evergreens keep the nitrates in check.
"Fear not, my young apprentice. Just change the tank water."
