Don’t worry too much about this; just sprinkle a little food in the pond and move back. After a few minutes, they will take an interest and eat.
1. Be Consistent
2. Serve High Quality Food
3. Variety is the Spice of Life
4. The Five Minute Rule
Remember, however, that larger fish need more food than small ones, so they may take a look at your plants for a snack. Not to mention the fact that if you are not feeding your fish, you are missing out on another whole level of fun that your pond has to offer.
5. Choosing the Best Food
Fish are adapted to the consumption of others in their food chain, so fish proteins are the best for fish. When you look at a bag of food and the first ingredient is wheat, is that the best choice for your fish? No, wheat protein is not equal to fish protein so keep looking. You should look for fish or other aquaculture proteins as the first ingredient in a decent diet for your koi and goldfish.
