This part will help you select the appropriate tank size, and also determine the volume of tanks you may already have. When you are selecting a location for your tank, don't forget about weight. Fish tanks are heavy when filled with water, gravel, plants, filters, ornaments, and of course fish! Also, you will have to take in consideration the weight of the stand or object you are placing it on.

Finding the size of tank you need,
or the number of fish for the one you have.
There are a number of rules about this topic. One is to allow 10 gallons
of water per fish. This seems to be allot but would make some sense for Goldfish.
This would allow PLENTY of room for them to grow, but it still seems a bit
much.
In terms of the number of fish that should be allowed in a particular
tank, the following guide should be useful:
| Freshwater tropical species | 10in.2 per inch body length | 25cm2 per cm body length |
| Freshwater coldwater species | 30in.2 per inch body length | 75cm2 per cm body length |
| Marine tropical species | 48in.2 per inch body length | 120cm2 per cm body length |
Note: In all the fish measurements the tail (caudal fin) is not
included.
Example: A tank 24x12x12in has a water surface area of 288in.2
and will comfortably hold;

You can determine the volume of an aquarium by using the following formula:
| Length x Width x Height (in inches) = Volume in 231 gallons. |
Multiply this figure by 8 and add the weight of the empty tank to get the
total weight of the tank when it is filled.
