I love it when there are no other lights on except for the tank light. I purposely push my back light timer so that the light stays on until 1 AM. That way, I can fall asleep to the awesome glow of my tank.
lol I would love to place some live plants in my 35G, but my loach would have a wonderful time uprooting them. Whenever I do water changes I always have to reroot the plastic plants.
