To save you some money i have a awsome light fixture for a 20gal. long/30 gal tank. It holds 2 bulbs and 2 flurescent lights(those long tube lights, dont know what they are called, lol.) Sale it to you for $30. Forget how much its worth but i know it aint cheap. I will post a picture of it later. If you can find it cheaper then i can drop the price lower. I have never used it and its just been collecting dust.
