Instructions

    • 1

      Determine what size of tank you want. This can depend on how many and what kind of fish you wish to purchase. In freshwater tanks, you need about one gallon for every inch of fish; for saltwater you need about five gallons for every inch of fish. Beginners should stick with freshwater since the fish are more peaceful and because saltwater tanks require extensive knowledge and daily maintenance.

      If you are building the aquarium from scratch, determine the right thickness of glass you will need. You will also need a sturdy stand that will be able to hold all the weight. Typically, one gallon of water weighs 8.3 lbs, and you will need one pound of rock per gallon, but some people use one pound of rock for every two gallons.

      Set up your tank by first putting a few gallons of water in the aquarium. Many people suggest buying water from a grocery store since tap water contains elements toxic to fish. Then place the rocks, but rinse them first to get off any dust and dirt that may harm your fish. After the rocks, you can place the plants and other décor such as plants, statues, or anything else you fancy. Fish enjoy having places to hide and will use all the decorations as ways to remember their territory.

      Set up your filter following the directions on the box. There are many different filters to choose from: bio wheel, canister, internal, wet/dry, and even an under-gravel filter.

      Use an aquarium test kit to know when your water is ready for fish. You must check the ammonia, pH and nitrate levels until the water is able to sustain fish. When these levels are off balance, you will see quickly what happens. The common cold of the fish world is called “ick,” and it shows up on your fish when they become stressed, either due to moving the tank or the levels being off. The best way to prevent this from happening is to wait until your tank is ready before purchasing fish.

      Purchase the fish. Remember that certain fish are healthier being in schools of three or more, whereas other fish must be the only one of its kind in the tank. When you bring your new pets home, keep them in their bags and place bags in the tank for about ten minutes, allowing the water in the bag to match the temperature of the water in the tank. Then open the bag, grab a net, and place the fish in the tank, being careful not to mix the store’s water with your own.
