Well, there are 2 types of fish, Saltwater Fish, and freshwater fish. Only put in saltwater if you own a saltwater fish.
Note: Saltwater fish could live safely in freshwater, but Freshwater Fish will suffocate in saltwater.
An aquarium needs to be cleaned for several reasons. One is to keep the water toxins at safe levels which requires regular water changes. The other is to clean algae from the glass so that you are able to see your fish.
No because the sand will make the water dirty, small rocks are usually the best.

yes but it not very safe or sanitary
Live parts to which an employee might be exposed shall be put into an electrically safe work condition before an employee works.
The reason why you need to do regular weekly (at minimum) water changes in your aquarium is due to fish waste. Toxins such as ammonia, nitrite, and nitrate will build up and cause harm, or even death to your fish.By changing out at least 50% of the water and adding new water (that is the same temperature as the old water) keeps the toxins at safe levels; your ammonia and nitrites should test at zero, and your nitrates at less than 10 to 20ppm.Also, make sure that you are using aquarium water conditioner per the instructions on the bottle to remove harmful chemicals (such as chloramine) from your tap water to make it safe for your fish.

Anything labeled safe for aquarium use. Beyond that, it depends on what type of fish you are keeping, and whether or not you have plants, for which type of aquarium substrate (gravel or other lining for the bottom) should be used.
