Best Automatic Fish Feeder Reviews (Top 3 Picks)

If you have an aquarium, you know how important it is to feed your fish regularly. But what happens when you go on vacation? Or if you work long hours and can’t get home to feed them on time? An automatic fish feeder is a great solution to this problem.

There are many different brands and low-quality fish feeders available, so it is important to do some research before purchasing one. In this article, I’ll review some of the top fish-feeding devices on the market. I’ll also provide some tips on how to choose the best automatic fish feeder for your aquarium.

How Does an Automatic Fish Feeder Work?

An automatic fish feeder is a device that releases a specific amount of food into an aquarium at regular intervals. A basic fish feeder has a hopper that is filled with food pellets or flakes. The hopper is connected to a timer that controls when the food is released. When the timer reaches the preset time, the food is gravity fed from the hopper into the aquarium.

More advanced automatic fish feeders have sensors that can detect how much food is in the aquarium and dispense accordingly. Some even have Wi-Fi capabilities so you can control them from your smartphone.

Most automatic fish feeders have an adjustable lever that allows you to control how much food is released. You can also usually set the feeder to release food multiple times per day. The device is either battery-operated or plugged into an outlet. 

No matter what type of fish-feeding device you choose, they all make it easier to keep your fish fed and healthy.

Do You Need an Automatic Fish Feeder?

Automatic fish feeders are often used in aquariums that are home to tropical fish, as they need to be fed more often than other fish species.

Here are three reasons why you should consider getting a fish-feeding device for your aquarium:

  • First, an automatic fish feeder can help you keep a regular feeding schedule for your fish. If you’re busy or away from home often, it can be difficult to stick to a regular feeding schedule. But with a fish feeder, you can set it to dispense food at the same time each day, so your fish always get the nutrition they need.
  • Second, it can help you control the amount of food your fish eats. Overfeeding is one of the most common problems in aquariums, and it can lead to serious health problems for your fish. A feeding device can also help you save money by reducing the amount of food you buy.
  • Third, an automatic feeder will cut down on the waste that food causes. And if you have multiple tanks, it’s difficult to keep track of how much food is in each one.

How to Choose an Automatic Fish Feeder?

Here are a few tips to help you choose the best automatic fish feeder for your needs:


The first thing to consider is the size of the fish-feeding device. You will need to know the dimensions of your aquarium in order to choose the right size feeder.

Capacity & Placement

Capacity refers to the amount of food that the feeder can hold, and placement is where you will put the feeder in your aquarium.

To determine capacity, you need to know how many fish you have and how often they need to be fed. A good rule of thumb is to choose a feeder that can hold enough food for your fish for 3-4 weeks. Placement is important because you need to make sure the feeder is easily accessible for your fish.

Feeding Schedule

Does the fish feeder have a flexible feeding schedule? Some models allow you to set when and how often they dispense food, while others have a more simplistic design that dispenses food at regular intervals.

The Pros and Cons of an Automatic Fish Feeder

A fish-feeding device can be a great addition to your aquarium. However, there are some pros and cons to using one:


  • Automatic fish feeders can be programmed to dispense smaller meals more frequently throughout the day, which closely mimics their natural feeding habits in the wild. This can help reduce stress levels and promote a healthier appetite.
  • It can be especially helpful if you work long hours or travel frequently, as it can help to maintain a healthy feeding schedule for your fish even when you’re not around.

While this may seem like a convenient way to feed your fish, there are a few potential disadvantages to using an automatic fish feeder.


  • Automatic fish feeders can malfunction and your fish may not get fed. This can be especially problematic if you have tropical fish that require more frequent feeding.
  • Another potential danger of using an automatic feeding device is overfeeding your fish. If the feeder is not set properly, your fish can end up overeating.
  • Also, if too much food is released, it can cause the water quality to decline and the fish to become sick.
