The Best Automatic Fish Feeder: Our Choices

Guide: Questions you should ask yourself before buying a fish feeder

Why should I buy a fish feeder?

Every aquarium enthusiast knows how important correct and regular feeding is for the underwater inhabitants. Often, however, professional and private commitments do not allow for this. A fish feeder can be a great relief in this case.

When you go on holiday, are on the road or have irregular working hours, you have to ask yourself how you can continue to feed your fish optimally. However, fish can go a few days without food.

Fish feeders are practical, easy to use and individually adjustable to the needs of your fish. They are available for both aquariums and ponds.

Even if you ask friends or relatives to feed them, the worry remains that they might overfeed them.

To give your aquarium inhabitants the right amount of fish food at a certain time even while you are away, you can get yourself an automatic fish feeder.

How does an automatic fish feeder work?

Automatic feeders for underwater fish automatically dispense the set amount of fish food into the water at regular intervals. The control unit must first be programmed to suit individual needs.

Automatic feeders are operated either with batteries, rechargeable batteries or with a power connection.

The automatic feeders have one or more feeding chambers into which the fish food is filled. The amount of food can be optimally dosed by partially adjustable openings and by the number of feedings per day.

With a fish feeder, you can leave your fish alone for a few days or even several weeks, or you do not have to feed them.

The period of time for which the food in the chambers is sufficient depends on four factors:

  • Size of feeding chamber – amount of food
  • Volume of the aquarium
  • Interval of feedings
  • Fish population

Which fish food is suitable for automatic feeders?

You can fill almost any dry food into automatic feeders. However, pay attention to the information on the packaging. Sometimes you are only allowed to fill certain types of food.

Live and frozen food is not suitable for automatic fish feeders. These types of food spoil quickly and can stick to the opening of the feeder.

The choice of food can vary depending on the species of fish. If you have several different aquarium inhabitants that require different types of food, you can purchase an automatic feeder with several chambers.

A multi-chamber feeder also allows you to add some variety to the fish’s diet.

Types of food often used in automatic feeders are:

  • Flake food
  • Granulated food
  • Food tablets
  • Sticks and pellets

It is important when using fish food in automatic feeders that it should be as uniform as possible. One type of food that is often used is granulate.

Be careful with flake food, sticks or food tablets, as these are not always suitable for automatic feeders.

Flake food can stick in the feeding chamber. Food tablets sink quickly and are therefore more suitable for bottom-dwelling fish. Tablets, sticks and pellets may be too large for the automatic feeders and therefore need to be reduced in size.

How much does a fish feeder cost?

Automatic feeders for the pond are usually more expensive than those made for the aquarium. Prices usually vary between 15 and 50 euros.

Fish feeders with several chambers are often more expensive because they are more complex and allow the feeding of several types of fish food.

Product type Price range
Fish feeder with one chamber 15-40 €
Fish feeder with several chambers 25-50 €

What is the alternative to a fish feeder?

If you are not going away for more than 14 days, you can also buy so-called holiday food for fish.

This is compressed food in the form of a cube or block that releases small amounts of food over a longer period of time.

Holiday food is much cheaper than automatic feeders, but there is a risk that too much food will be released at once, causing the water to tip over.

Decision: What types of fish feeders are there and which is the right one for you?

There are basically two different types of automatic fish feeders:

  • Fish feeders with one chamber
  • Fish feeders with several chambers

What distinguishes a single-chamber fish feeder and what are its advantages and disadvantages?

Feeders with only one chamber are usually a feeding drum. There is often a round feeding chamber with a size-adjustable opening that rotates so that the opening ejects fish food at a regular rhythm.

While such a feeder is easy to operate and adjust, it can only be filled with one type of food. So there is little variety for the fish.

The limited dosage could also become a problem if your aquarium inhabitants need different types of food.

One advantage of this model is that many feedings are possible and the size of the opening is adjustable. This way, the amount of food can be adjusted.

  • Uncomplicated
  • Large feeding drum
  • Many feedings possible
  • Adjustable opening size
  • Limited dosage
  • Only one type of food possible
  • Food can stick

Since a large amount of fish food is stored in the feeding drum for a long time, there is a small risk that the food will stick together if it is too moist. Some products therefore have built-in ventilation.

What distinguishes a fish feeder with multiple chambers and what are its advantages and disadvantages?

In fish feeders with multiple feeding chambers, each chamber is filled individually. The number of feedings that can be made is equal to the number of chambers.

A fish feeder with multiple chambers is good if you have different aquarium inhabitants and therefore want to feed different types of food.

  • Exact dosage
  • Varied fish nutrition
  • For several types of food
  • Tedious filling
  • Fewer feedings possible

This model allows precise dosing, as one chamber is completely emptied with each feeding.

Buying criteria: Use these factors to compare and evaluate fish feeders

In the following, we will show you which aspects you can use to decide between the many possible fish feeders.

The criteria you can use to compare fish feeders include:

  • Easy to adjust
  • Stability
  • Energy supply
  • Suitability according to feed type

Ease of adjustment

Some fish feeders are complicated to set up. This can be very time-consuming and can get on your nerves. Therefore, when buying, make sure you buy a feeder that is as easy to programme as possible.


Of course, it is especially important that the fish feeder is stable and does not fall down easily. Most stand firmly on the lid of the aquarium. Make sure that the machine is tip-proof.

For open aquariums, you should also have a vertical bracket so that the feeder can be attached to the glass.

Power supply

You can decide whether you want a device that runs on batteries or rechargeable batteries. A third option is to buy a fish feeder that needs to be plugged into a power outlet.

Batteries and rechargeable batteries have the advantage that they are energy-saving and do not need to have a socket nearby.

With vending machines that are plugged in, this can only happen in the rare event of a power failure.

Suitability according to feed type

As already briefly mentioned, sometimes only certain types of feed are suitable for an automatic feeder. Depending on the type of food you use most often, you should choose a suitable fish feeder.

If you have to or want to feed your aquarium inhabitants as varied a diet as possible, you should go for an automatic feeder with several chambers. Here, several types of food can be fed in parallel.

Facts worth knowing on the subject of automatic fish feeders

How do I install the automatic feeder in the aquarium?

Fish feeders are usually placed on the cover of the aquarium. Below the opening of the feeder, the cover is pushed to the side a little so that the aquarium is open at this point.

Sometimes aquariums are even specially made so that the feeder fits into an opening provided for this purpose.

Test your fish feeder a few days before you go on holiday. This way you can make sure that everything works and your fish are well fed.

How much food do my fish need?

To find out the right amount of food for your fish, you can try out how much food your aquarium inhabitants eat for a few days.

It is advantageous to have several small feedings per day, as small amounts are eaten more quickly and the risk of overfeeding is reduced.

Do you know that you should feed your fish too little rather than too much?

Fish can go several days without food, so it is better to feed a little too little than too much. Overfeeding is a common problem in fish keeping. Many fish do not have a feeling of satiety and therefore keep eating. In addition, overfeeding pollutes the water in the aquarium.

If in doubt, you should rather set a lower food quantity. Too much food pollutes the aquarium water and poses a higher risk for the fish.

In the table below you will find some hints to help you recognise if you are feeding your fish too much or too little.

Situation Clues
Too much food food floats around for minutes after feeding, bulging fish bellies, algae
Too little food fish fight over food, belly bent inwards, nibbling on aquarium plants

Do I have to clean the fish feeder in the aquarium?

Special cleaning for the fish feeder is usually not necessary. If the food should stick due to increased humidity, you can clean the removable feeding drum under running water.

Some models even have their own ventilation flaps. This prevents air from entering the feed chambers and the fish food from becoming too moist.
