An aquarium hood serves several purposes. Usually it provides a light source; prevents fish from jumping out of the tank; and reduces evaporation, noise, and the release of foul odors. Providing proper lighting is not essential, but can enhance the coloration of fish. Too much light can be as much of a problem as not enough light. Fluorescent lights in hoods may emit more light than needed. If your fish appear frightened in a well-lighted environment, try dampening the intensity by placing construction paper under the light device. If your tank receives adequate lighting from surrounding lights, a hood may not be needed, and covering the tank with a piece of glass may be sufficient and less expensive. Nevertheless, some type of cover should be used.
The hood is build from 1/4" thick tempered particle board (masonite). The hood is 48 3/4" long and fits over the top of a 48" long aquarium. It is 10" wide and 2 1/2" tall. The hood is braced internally by two crossing braces each of which has two parts - a top and bottom. The braces also provide support for four T12 or T8 fluorescent tubes. Wiring for the light is run behind removable covers at the rear of the hood that also serve as part of the reflecting surface. All internal parts of the hood are painted gloss white and the inside top and front slope of the hood can be lined with aluminum or (if a grounded shield is not required) with reflective Mylar. Ventilation is provided by holes at the top of each end of the hood.
The hood can hold up to four full length bulbs and the bulb connections are all water proof (safe from splash but maybe not submersion). When the hood is open, there is lots of room to clean the tank. Do not use any metal because this will cause the death of any reef tank. Keep away from metal screws, metal hoods, copper or anything metal that could leach into the tank.

Cats like fishes very much. If u have a cat or in nearby then it will be quite difficult to keep the fishes in lonely place then there must be something for that, so, a cat-proof aquarium hood, it's primary feature being a wedge shaped hood with a smooth, diagonal incline on the top as opposed to the normal flat design with rectangular light boxes. This way, any cat attempting to jump atop the aquarium In would simply slide off, with no places to cling onto. In this, let's call it a CPAH for short, the lights and filter and/or air pump would be safely encased inside this wedge. The openings for feeding would be doors directly level with the shell, and perhaps you could purchase a model with an optional auto-feeder (for you lazy fish enthusiasts). However, relying solely on the wedge and gravity to protect your fish is probably not a good idea (when you have a cat as crafty as mine, at least). So this particular CPAH would also be equipped with pressure sensors that (when pressure was applied to certain areas for several seconds) would set off an alarming noise (perhaps loud dog barking, sirens, etc) to send any offending cat running for cover. These things, I believe, would eventually teach a cat that some things are best left alone (or at the very least keep your cat from causing harm to your aquatic pets or even to itself).
