When setting up a home aquarium for a small child always remember…
Safety First!
If you’ve decided to begin the wonderful hobby of fish collecting for a small child then a glass aquarium is probably not the best bet. 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. That’s 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. The most dangerous tank is a glass fish bowl.
What Size Tank?
Many fish guides claim, “If you are new to fish collecting I would suggest you start with something small…”or they say things like, “stick with ten gallons and under to keep your expenses down until you decide this is for you”. We both know this IS for you or you wouldn’t be reading this.
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 small 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 tank will not be wasted money should you decide to start with the smaller size aquarium.
These days there are many nice, small aquariums for a first timer or someone who merely lacks the room. Half-gallon fish containers, Hexagonal 2 gallon tanks and when it comes to 5-gallon and 10-gallon tanks, there are so many different designs I could write an entire ebook on the topic LOL!
