Fish Crazy
So most fish don't need a light on, ever. Its just for us, right? So what if I rigged up instead of a timer...a motion sensor. So that whenever somebody is nearby to look at the tank, the light is on - and when no one is in the room to see it, its off. Anyone ever tried anything like that?
Feeding would be effected, as would sleep patterns... resulting in ill health and reduced immune systems, eventually death
