Thanks yote! I'll try that. I have put a regular flashlight on the rock but just during the day. Just what I need.....more encouragement to obsess over my LR. This hobby has become an addiction. My neighbor recently asked me if I bought a big screen TV because she saw me through the window with my chair pulled up to the tank. She was like "Why are you sitting so close to the TV". I explained that it was my new tank and went into great, gushing detail about it. She didn't seem as excited as I was....oh well.
