So I was messing around a little with my tank this afternoon and decided to put less light on it.
Give it a more natural dimly lit look. I don't have real plants (can't with the school of around 20 Silver Dollars), so the only need for light is to see the fish.
I put 1 x 12" light to about a 3 foot section. I think it looks awesome. Picture is kinda crappy and doesn't do it justice, but its a neat look.
the dark spot in the middle is because of a massive piece of wood i took out of the lake. Its about 3 feet long, and goes from the front to the back of the tank. The fish all hang out around and under it,
