How long can fish go without being fed?
by
Healthy adult fish can go for a week or two without feeding. However, young fish don’t have the fat stores of adult fish and they cannot go without eating very long. That doesn’t mean you should routinely skip feedings, but your fish can safely be left without food over a long holiday weekend.
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.
How much do I feed my fish a day?
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!

However, overfeeding fish can be a serious problem that can cause fish becoming lethargic and sick, and even lead to death. Overfeeding your fish can not only affect the health of your fish but can also have a negative impact on the overall health of your aquarium.
