I have a 29 gallon tank with no light and I keep it in my laundry room away from my other tanks. I usually use that tank for a breeding pair of something (privacy). Right now it has no light and is mostly bare. I just need something to put some light in the tank. It does not have to be as big as the tank. I just don't want the fish in the dark the whole time and I don't want to leave the room light on all day. I live in Florence if you have something laying around that you're not using or could spare.
