Benefits Of An Automatic Fish Feeder

My friend tells me that they don’t have enough time to feed for their fish every day.

He tells me that their fish looks quite stress and they don’t know why.

And then his fish has some symptoms of sick. It won’t eat for about three days.

This are the problem you can avoid by having an automatic fish feeder.

An automatic fish feeder will help you:

  • Control the amount of food for your fish. Help it not too full or not too hungry.
  • Feed your fish every single day. Your time is now free.

In short, it’s better for the health of your fish with the proper amounts at regular intervals.

The danger of overfeeding is gone and the environment within the tank will be better since there won’t be excess food on the bottom.

Buying Guide: What Features To Look For In Automatic Fish Feeder?

There are several metrics to consider when buying an automatic fish feeder. Which are the size, machine’s lifespan, battery life, time & quantity controller, feeding frequency, and ventilation system(optional).

Correct size

Food that can be held in the container is an important consideration. Particularly if you have fish that tend to eat a lot. In that case, choose the right size is the most concern you should have.

Big fish requires more food than a tiny guppy. So you need to be sure your feeder has the right capacity then you don’t have to keep repeating food refill it too frequently.

On the other hand, if you only have a few small fishes you don’t need an automatic one with a very large pin.


A long lifespan fish feeder would be great if they can live a longer lifespan.

The manufacturers estimate that the typical feeder will reach the end of its expected three years lifespan or more without an issue of using it.

Battery Life

Some automatic fish feeders run off of rechargeable batteries but most use AA disposables.

Battery life will depend on the number of features, the number, and type of batteries involved. However, some will last up to seven months or more.

It might be helpful when the feeder has a low battery power alarm light.

Time & Quantity Controller

If you are considering an automatic feeder without a dependable timer isn’t much good.

Besides, you’ll need to be sure the feeder you’re buying has a reputation for reliability and that the timer is easy to use with simple instruction.

The LCD screens will show you precisely what you are inputting would be a great help to people who are unfamiliar with automatic feeding technology.

Moreover, that goes for the quantity of food the feeder is dispensing as well. Research your fish and find the right number of times to dispense food and the amount you should distribute before programming your automatic aquarium feeder.

Feeding Frequency

Some feeder brands only provide you an option to feed once a day. It might not suit your fish because not all of the aquarium fish will it only one time per day.

Many small fishes eat many times a day with a lesser amount of food.

So, having a feeder with a feeding frequency option should be the important criteria to look at.

Ventilation System(optional)

Fish keepers worry that the food will be clumped together if the moisture built up in the feeder.

But some new fish food brands can handle that if no water gets in the feeder. In the case of water get in the machine. You should have a proper fix action immediately.

However, that is very good if the feeder has a small built-in fan while others have vents built into the food bin to allow moisture to escape.

Otherwise, you need to keep checking it at least every day.

10 Best Automatic Fish Feeder

We already know the benefits of the automatic fish feeder. Now, what is the best fish feeder for you?

This auto feeder is ideally for the very less number of fish in the tank because they only produce feeding once or twice a day.

You will see the fishes might have some signs of hungry because of the less amount of food was giving.

However, there are some positive rates for this product. It was given by the keepers who only have one fish in the tank. And it doesn’t require too much food.

One extra thing is Pellet food is not recommended due to its density.

And also the product will become clogged if larger pellets or flakes are used, and moisture only gathers inside and clumps the feed if the feeder is placed too close to the surface of the water, allowing it to scoop water inside during a rotation.

However, with tropical granules, which are smaller than pellets, it works well.

We believe that granules would be the best type of feed to use for this product.

Automatic Fish Feeder Saltwater Tank

Last update on 2021-03-03 / Affiliate links / Images from Amazon Product Advertising API

The idea of having a proper saltwater tank automatic feeder is because the salt.

Are you having a saltwater fish such as puffer fish or any other fish?

Do you use the auto feeder for a long time? You will see that some of the accessories will be rusted.

Therefore, the problem for the saltwater tank is not just an expensive auto feeder but about dry maintainability.

We would suggest you choose the feeder with the higher tray/panel to keep it dry. Or you can set up a higher spot to install the feeder.

We prefer the second option because not all the products in the market satisfy the first criteria. But for the second, that’s much easier.

With the Eheim Automatic Feeding Unit, you can easily set a proper spot to keep it away from the saltwater.

What we likeWhat we don’t like
Simplicity: this product is super simple to manage and program.
Consistency: a common benefit of switching to automatic feeders.
Dependability: you will be using this device for months without a hitch.
❌ Different types of food will require a second feeder.
❌ Food of different sizes could get stuck.
