Hoods are very important part of your aquarium; they are used to keep the heat in the aquarium and to keep fish from jumping out. A hood will also keep any materials from going in the aquarium like dust and other foreign objects. The best lighting fixture to get is a hood with glass at the bottom to block water from evaporating up into the electrical components.
Lighting is also very important. Most fish and plants like some light. Some of the fish that don't need a light it is still recommended that you use one and just don't run it as much. There are two different types of lighting you can get with your hood, which include incandescent and fluorescent. Incandescent bulbs are cheaper but the cost for the replacement bulbs in the long run is expensive as the fluorescent bulbs. Incandescent gives off more heat than the fluorescent and it is on the red and yellow side of the spectrum, which is unsuitable for growing plants.
Fluorescent generates less heat and lasts years compared to the incandescent. There are different colored bulbs to help bring out the fish's color better and help the plants grow faster and better.
