Animal experts and nutritionists suggest that one should always watch his or her fish’s food consumption. Moreover, your fish should complete the portion within two minutes to avoid flocculation in the fish tank or aquarium.

If you have a fish, you must monitor its characteristics and eating habits. Once you have evaluated your fish’s needs, you must set a specific number of fish flakes for every portion and make it a routine.

Try to follow the same portion size for an entire month and continue monitoring your fish’s reaction and activity.

Moreover, if you have any doubts about how much to feed your fish, you can experiment with your fish food and portion size. If you are an amateur or a beginner, you must follow the basic thumb rule of feeding fish in your aquarium.

It would be best to provide them with a limited quantity of fish flakes that can be digested within 4-5 minutes. Create a timetable, follow it thoroughly, and constantly monitor your fish’s intake and metabolism rate.

If you observe flocculation or pollution caused by the fish flakes or undigested matter, avoid overfeeding them. Always use soft and unfrosted food that your fishes can easily digest.

When Should I Feed My Fish?

If you are a morning person, it would be best to feed your fish at the start of the day. However, you can also feed them at dusk.

Moreover, if you feed your fish consistently throughout the day, schedule their feed timings and follow the same routine. Fishes in the aquarium can be fed any time of the day; however, it would be best to feed them during the day or night.

Just like every living organism, fishes also digest, excrete, and produce matter.

Hobbyists and aquarists make their fishes fast for two to three days or even a week, so they can clear their digestive systems and start fresh.

What Are the Signs of Overfeeding Fish?

You would always question how often should I feed my fish? Many hobbyists take a keen interest in feeding their fishes and maintaining their aquariums.

However, you must always ensure that you are feeding a limited quantity of fish flakes. If you are constantly feeding your fish, they would consider your presence as a food provider only.

Moreover, if you are feeding them an extra portion, there is a fair chance that they will waste that food, which would be seen floating in your fish tank.

As fish flakes are released in water, they become softer and lose their nutritional content when over-exposed with water particles.

After cleaning your aquarium, if you observe cloudy water with suspended particles, it is because of the uneaten or leftover fish food.

What Happens If You Overfeed Fish?

Before you overfeed your fish, recall how often do you feed fish. Overfeeding sometimes kills them; the waste food sinks at the bottom of the aquarium and pollutes the entire internal environment.

Pollution caused by leftover food particles interrupts oxygen supply and light intensity reaching the bottom of the fish tank.

Like mammals, if fishes consume excess food, they will have a problem while digesting food particles. To avoid this, you can install an automatic food feeder and constantly monitor it’s working.

Suppose you are keeping your fishes in an artificial environment, an aquarium.

In that case, you need to ensure that you are providing them with a constant supply of fresh and clean water to survive and stay healthy.


Fishes are among the unique creatures created by God. Whenever you observe a fish tank or an aquarium, you are mesmerized by its colors and internal environment.

However, you need to keep a quality check over your aquarium and feed them within certain limits to keep it natural.

Hobbyists and caretakers need to ensure they feed their fishes the right amount and portion of food.
