Intensity & Duration of Light per Day
Host Sea Anemone Survivability Survey Stan Hauter
The light wattage per gallon of tank water seemed to have an affect on the longevity of the anemones in the study. Light amounts at the lower end (below 3 WPG) shortened the life span by about half. It appears that lighting above 3 WPG and even more so into the 4 WPG range was beneficial, but above 5 WPG didn't seem to add significantly.

The light period per day that was given to the anemones in this study seemed to have a significant affect on their lifespan in an aquarium. As the graph below indicates, increasing the light period from 9 to 11 hours to day was beneficial, while anything over 11 hours seems to have actually had the opposite effect.
