Some people don’t like to have a dog or cat as a pet. Some people prefer to let a few fish swim lazily in their tank. The problem with keeping fish as pets is that they aren’t exactly determined to get your attention when they’re hungry.

That’s why it’s really easy to forget to feed them, especially if you have to do it several times a day. And that’s why you need an automatic aquarium feeder.

When I was a kid, the idea of ​​automatic feeders confused me. We had a gravity-based one for my cat every time we traveled, which encouraged the already chubby cat to go crazy with that kibble, and I never thought I’d want them for any other purpose.

But as an adult I have realized how valuable it is to have a high quality and well-made automatic fish feeder.

There are days when I am too tired to get up and sprinkle the food that betta fish and fire fish need. There are weekends when I run like crazy and try to do all those errands that I don’t do during the week.

And then there are the travel weeks. I cannot ask my cat to feed the fish, so I use an automatic feeder. However, when I started I thought all feeders were pretty much the same. But since I was doing some research and looking for them for my own use, I realized why we need to dig deeper into the products.

Some of them work great, some don’t work at all, and some work great just for specific things. So if you’re anything like me before you start farming fish, you’ll want to know a few things about these automatic fish food reviews and how to interpret them.

What is the best automatic fish feeder?

An automatic fish feeder is a great solution if you are away from home for some time. Consider getting one of these as there aren’t really many options available.

You can ask a friend or neighbor to feed the fish in your tank while you are away, but that option may not be reliable. You need to get one of the best automatic fish feeders available today.

We recommend that you buy the Uniwood Digital Automatic Fish Feeder, the first on our list. The price is good, yet the ease of use, reliability and quality are excellent.

This is the device you can buy if you don’t want to worry about whether or not your fish are getting enough food. It is amazing to have this assurance and to know that you will not have to feed the fish in your tank yourself for years to come.


How does the automatic fish feeder work?

An automatic fish feeder is made to provide the correct amount of fish food in your aquarium at a specific time every day. Some feeders can be configured to provide food more than once a day. This will help ensure that your fish are well fed when it comes time to feed them in case you forget or just go on vacation.

Automatic fish feeders run on batteries or are electrically powered via a power cord. The advantage of battery chargers is that you don’t have to worry about power outages or electric shock. The advantage of electric feeders is that you don’t have to worry about the battery draining or dying.

Each feeder comes with a variable number of containers to pre-fill with fish food. The feeder will turn the containers on a timing mechanism so that the food falls into the tank at a specific time. This allows you to feed fish and other aquatic animals all the time without overfeeding them.


How to set up an automatic fish feeder?

Automatic Feeder Configuration

Before proceeding with the preparation and configuration of the device for installation and use, you should inspect the device for damaged or loose parts. Low-cost automatic feeders often come with broken cells that store food. You have to examine the cells thoroughly.

The list of automatic fish feeders in this article is the best product to choose. Plus, as they are guaranteed by Amazon, you won’t have to worry about any damage.

Once you have unpacked the automatic fish feeder, you must connect the device to a power source if it is electric. For battery operated fish feeders you need to insert two AA batteries which will start the display LED.

The Best Automatic Fish Feeders comes with a dispensing inlet that opens when the feeder discharges the feed from the cells. You can customize the settings for the download input. Most manufacturers recommend using the inputs at the highest setting.

Do not use the container to fill the fish food into the cells before cleaning the hopper. This procedure must be done with care. If the container or chamber is not clean, it can contaminate the food and cause it to spoil and possibly kill the aquatic pets.

Adjusting the amount of feed

There are two ways to adjust the amount of feed in automatic fish feeders. Many of these devices have a customizable dispensing inlet that regulates the amount of food that is released in each feeding cycle. However, there are some automatic fish feeders for the aquarium that expect you to fill the cells with the estimated amount of food.

Generally, most fish and other aquatic pets require only 1-3 meals per day. Generally speaking, it is strongly recommended to set the amount of food to the limit that aquatic pets can devour in 5-10 seconds. This will definitely avoid any ammonia or cloudiness issues that can cause great harm to aquatic life.


Keeping your fish healthy and safe will never again be an unbearable task when you own one of these reviewed products. Regardless of where you are, away from home or at home, you can simply feel free from the task of feeding your fish, knowing that these Best Automatic Fish Feeders will get the job done.
