Aquariums are expensive and you may end up spending a lot of money for it. A smart buying exercise will help you get a good aquarium within reasonable price. Before you start looking for an aquarium it will be wise to know a few things. You should be clear as to the number of fish, type of fish and the kind of decor you would like to have.

It needs to be understood that starting an aquarium is like attempting to set up a small ecosystem, which could have living plants too. It will be required to maintain the correct pH balance. This is difficult in a small tank. Thus, you must not attempt to start an aquarium with small tank with a few fish. It is advisable to start with about twenty-gallon tank. This will ensure that the fishes are not cramped.

When trying to determine how many fish you want you'll first want to start with a small amount. Four or five fish may be a good starting point. You can always add more fish to your aquarium if you don't feel that you have enough. When purchasing your fish you first need to decide if you want fresh or salt water fish. Most of the tropical fish are salt water and you can't have both.

It is essential to understand the compatibility of the fish with each other. Some fish do not get along with others and eat the smaller fish. Take the advice of the employee at the pet store or you can look for this information on the Internet.

Then decide what you want to put in the tank for decoration. Just ensure that the item you put in the aquarium have been purchased from the pet store. Do not put anything that you might have picked up from the beach, especially the gravel. The gravel that you pick up at the beach is not what you find at the pet store. The items from the store have been treated and will ensure that the balance inside your aquarium is maintained.

Okay, you have your fish and you have your tank. Now you need to add water. Tap water has to be treated before you can put your fish into it. Most of our drinking water contains chlorine and is harmful to fish and plants. You will need to remove it before you add it to your aquarium.

The fish is very sensitive to the water temperature in the aquarium. Any incorrect temperature can be fatal for the fish. Use a thermometer to ensure that the temperature is not too hot or too cold. It is recommended to maintain the water temperature between 70 and 80 degree Fahrenheit.

You should also consider what type of food you intend to feed your fish. There are fish flakes and pellets that are available, both of which should be fine for most fish. You can check with the pet store if they recommend any special food but most fish aren't fussy.

Some people are of the opinion that just placing a few gold fish in a bowl and hoping that the fish will be fine. However it takes much more effort. Starting an aquarium and then maintaining it can be very enjoyable and satisfying.
