The weight of Koi can be approximated by using the formula Length3 / 1650. Of course each fish
has a slightly different body shape and this should be considered in relation to the weight given by this formula.
The Feeding Calculator will help you estimate how much food your fish should be getting.
Use:
Enter the length of the fish in inches or cm. For a normal Koi, the length would be from the mouth
to the end of the tail. For a Long Fin Koi, use the length from the mouth to the start of the tail and be sure to check the LF box.
