Autumn is one month that your own environment can be a bit unpredictable as the
weather changes fast, hot one day and cool and damp the next. Water temperatures
in the fall months are going to be affected by the changing temperatures
outdoors. The water is going to remain warmer a lot longer than the outdoor air
is going to be warm, so you don’t have to worry to much about the fish as the
temperatures drop and change quickly.
For the koi fish, they will begin to eat more as the weather gets cooler and the
temperatures begin to drop because they are going to want to fatten up as they
realize winter is setting in.
Feeding during the autumn months is going to more important than it was all
summer long. During the summer months the plants and insects that are available
around the pond give the fish plenty to eat, but in the autumn months, food
begins to become a bit scarcer and the fish want to eat more. Preserving your
fish and helping fish survive over the winter months will become important for
the pond owner in the long run, so you are not investing continually in buying
fish.
As the water becomes overall cooler, the koi are going to eat less and will move
about less in the pond. It will take three to four weeks before the water
temperatures are going to be as low as the air temperatures so you will not
notice the fish eating less to begin with, but you should continue feeding the
fish in the first few weeks of the fall months when the outside air is cooling
down.
One of the best types of foods that you can feed your koi when the weather is
going to be turning to a winter scene is that of wheat germ pellets. Wheat germ
pellets have high cereal content, which are going to give your fish everything
needed to help boost them through those winter months without too much stress.
