I currently have it set up with a timer to turn on at 2pm and turn off at 10:30pm. The plants seem happy, but I noticed that in the last hour or two that the light is on, Louie glass surfs almost exclusively. I know this sounds stupid, but should Louie's 'bedtime' be earlier? Is 8.5 hours of light sufficient for the plants? Too much? Any advice would be appreciated.
Assuming that the tank is in a room that receives NO natural light, I would personally have the light set to about 8 hours, unless you're trying to propogate plants, or breed your betta (in which case, 12 hours is recommended).
If the room DOES receive natural light, he may be picking up on the fact that he's seeing the sun come up about 7ish, but not go down until much much later than normal. Even in High summer, if you live in a more temperate area the days are only about 13 hours of light. Maybe you should try pushing your timer back to, say, noon to 8 pm.
