Enter the tank volume and the average size of the fish to determine the appropriate number of fish for the tank. This calculator helps to maintain a healthy environment for aquatic life by preventing overstocking.
Fish Per Gallon Formula
The following formula is used to calculate the number of fish per gallon.
FPG = frac{TV}{FS / 12}Variables:
- FPG is the number of fish per gallon
- TV is the tank volume (gallons)
- FS is the average fish size (inches)
To calculate the number of fish per gallon, divide the tank volume by the average fish size converted to feet (since there are 12 inches in a foot). This calculation assumes one inch of fish per gallon, which is a common rule of thumb for stocking freshwater aquariums.
What is Fish Per Gallon?
Fish per gallon is a measure used by aquarium hobbyists to estimate the number of fish that can be safely kept in a specific volume of water. This measure helps to ensure that the biological load of the tank does not exceed the capacity of the filtration system and that the fish have enough space to thrive without stress.
How to Calculate Fish Per Gallon?
The following steps outline how to calculate the number of fish per gallon.
- First, determine the tank volume (TV) in gallons.
- Next, determine the average size of the fish (FS) in inches.
- Next, gather the formula from above = FPG = TV / (FS / 12).
- Finally, calculate the number of fish per gallon (FPG).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
tank volume (TV) = 55 gallons
average fish size (FS) = 2 inches
