How much is too much to feed a fish?
As for how much food to feed, a good rule of thumb is to feed no more than the fish will consume completely in five to ten minutes. 3 When in doubt, underfeed! You can always give them another small feeding if necessary. However, if you overfeed, the uneaten food will produce wastes that can be harmful to the fish.
How often should you feed fish?
You should feed your fish two to three times daily. A few flakes per fish is sufficient. The fish should eat all the food in two minutes or less. Overfeeding can cloud your water and harm your fish.
