Some tanks come with hoods and some don't. Hoods provide cover for the tank to keep fish from jumping out and they also provide light. When choosing your fish tank lighting you need to consider what type of fish you will be keeping. Incandescent lights can give off a lot of heat. These lights are not recommended for any fish that will be living near the surface of the water. Fluorescent lights produce less heat and are usually inexpensive they are ideal for even surface dwelling fish because of their low heat output. For tanks that will have live plants the better choice is the incandescent lights which can stimulate plant growth.
