Feeding your fish once a day is a nice schedule to hold yourself to. As long as you feed your fish enough then it doesn’t matter if you either feed your fish once or twice a day. Feeding your fish too little amounts of food can result in your fish going into starvation mode.

Most owners, however, prefer to feed their fish twice per day as their hunger will then be dimmed better throughout their day which results in happier fish.

What happens if you don’t feed fish for one day?

Generally not much will happen when you don’t feed your fish for one day. Most fish will have fat reserves that enable them to go without food for several days in a row. Also, if there are plants located in the fish tank then fish will start to eat various bugs that can be found in these plants.

If fish, however, are very fragile, haven’t eaten much food recently, are thin, and are in a bad condition then fish can die if they aren’t fed for one day.

Can fish not eat for 3 days?

Adult fish can survive without food for several days in a row and therefore it is also likely that adult fish will survive if they happen to go 3 days without food. Younger fish, however, need to be fed at least every 2 days which could mean that young fish might die if they go 3 days without food.

Young fish cannot survive for too many days in a row because they haven’t built up any fat reserves that adult fish normally have built up.

Can fish survive 5 days without food?

It is dependent on how old the fish are and also on which species of fish you’re keeping. Generally, you can expect young fish to not survive it when they go 5 days without food because they don’t have any fat reserves. Older fish, however, will likely survive going 5 days without food.

There are even fish species out there that can last up to two weeks without eating any food, however, you can also be sure that these fish will also have to be adult fish with fat reserves to survive for about two weeks in a row.

Conclusion

Now you know that fish can starve to death just like any other animal that lives on this earth. Therefore, it is of high importance that you establish a feeding schedule for your fish, so that you won’t be able to forget to feed your fish.
