Okay, so I bought a mini bow 5 gal tank. I have two Balloon Mollies in it. The light bulb this tank came with... is extremely dim, and discolors my white molly, to gold, and turns everything yellow. I have a bulb thats similar to a florescent bulb, and I screwed it in, and its bright, and makes the aquarium light up perfectly, like at the pet stores, but it's pretty bright. Can the light be TOO bright?
