Starting a Fish Aquarium? Do it Right the First Time!

begin with a 20-gallon tank. Many fish get much larger than when originally purchased and a larger system really is easier when it comes to cleaning and maintenance. But at the end of the day it is what you want to do, and that is the joy of starting an aquarium...

What now?

What do I feed them?
What environment do the fish feel most comfortable in and how big will they get?
What types of fish will my new fish get along with?
Where should I place the tank?
What do I do if they start fighting?
What type of aquarium stand will support the weight?
What type of filtration system should I use?
How long can I keep a fish in a small tank before I have to up-grade to a larger tank?

Lots of research is necessary for a healthy, well-balanced tank.

The first thing is planning on exactly what your goal is going to be. Visualize what you really want... and write it down. What size tank, what variety of fish, the filtration system, the lighting and chemicals needed. Plan everything that is required for the aquarium setup and then start with the steps one by one.

Safety First!

If you have decided to begin the wonderful hobby of fish collecting for a small child be sure to teach them proper etiquette. Banging the aquarium sides with toys will have dire results. Not only is it nerve racking and unhealthy for the fish, but also broken glass, water and flopping fish on the carpet can be a stressful and difficult thing to clean up!

One gallon of water weighs approximately eight pounds, therefore ten gallons weighs around 80 pounds. This is not including the aquarium, the fish and all the accessories! So as a general rule of thumb, to determine the approximate weight of a completely set up aquarium, I figure 10 pounds per gallon.
I highly discourage buying a one-gallon tank for your goldfish. People have the concept that "a cute little child needs a cute little fish tank". Believe it or not, a one-gallon aquarium is very difficult to maintain. The reason being is the amount of cleaning, mechanical filtering and water changes are more than double a 10 gallon or more tank.

Do it right the first time!

I highly recommend starting with nothing less than a 20-gallon tank. Many fish get much larger than when originally purchased and a larger system really is easier when it comes to cleaning and maintenance. But at the end of the day it is what you want to do, and that is the joy of starting an aquarium. A smaller aquarium can later be used as a breeding tank, sick tank, behavioral evaluation tank or food tank (fish kept as food). So realize that a small 10-gallon aquarium will not be wasted money should you decide to start with the smaller size because you'll already have the equipment when you decide to take the hobby to the next level. These days there are many nice, small aquariums for a first timer or someone who merely lacks the room.
