Sure, I'll take a picture tonight after work and post it. It's pretty simple- plastic wrap over the top, but because of the heater and filter there's a space where air can get in underneath the plastic. And then I have an LED desk lamp that I got at Walmart and I just have that set up right over the tank. The light is so bright I can't look at it directly. I think it's good for my plants because I moved in a moss ball from my other tank that wasn't getting much light and two days ago it was a very weird color, but now it's bright green again.
I think the lamp is a small version of those LED plant growing lights, because when I look at it when it's off, it's a panel of 12 LED's, I think. But when it's on it looks like one light because, like I said, it's so bright I can't look at it directly.
Anyway, yeah, I'll post pictures tonight.
