Im wondering if my tv prevents my 8 discus from getting a good nights rest. I have a big flatscreen thats fairly bright with 5.1 surround sound in my room about 6-8 feet away from my 55 gal. I go to sleep real late sometimes 12-3am watching tv and i always see my fish swimming around. i tried putting a blanket over the tank at night yesterday, but when i removed it in the morning my fish got really spooked and swam into the tank sides and the driftwood. what do you guys think?
