Automatic Fish Feeders

When you own a fish, feeding is the one opportunity you have to truly interact with your pets — for that reason, many people prefer to feed their fish by hand.

If you have a busy schedule or if you go on vacation, however, it’s important to make sure that your fish are still fed regularly. In those situations, automatic fish feeders can be a great solution.

An automatic fish feeder uses a built-in timer to release food at a specific time. That way your fish will be fed when they need to be, even without you being there.

Since portion sizes are crucial for fish, most feeders allow you to create portion controls, so you can control how much food will be released at each feeding. With a great fish feeder, you can head to work or take a vacation, all the while knowing that your pets will be safe and fed in your absence.

If you’ve started to look for an automatic fish feeder, you know that there are many available models. To make your search easier, we have sorted through the various feeders and picked out the best options. Here are our top five recommendations for an automated fish feeder.

Buying Guide

Because a fish feeder takes over the nutrition for your fish, it’s crucial to find the right model for your situation. Here are some factors to consider as you shop.


If you have a large fish tank, or if you travel for long periods of time, it’s important to look into the capacity of each fish feeder. If it’s too small, it won’t be able to hold enough food for your needs. It’s also a good idea to avoid feeders that hold much more than you need since they can put undue stress on your tank. Plus, when food turnover isn’t high enough, the storage compartment might become damp or moldy.

The best option? Look for a feeder that’s slightly larger than your maximum requirements. This way you'll have a little wiggle room just to be safe.


The controls on an automatic fish feeder determine how easy it is to use. Look at the buttons and screens on your top models. Are they easy to understand? Are they large enough to push accurately? Does the feeder come with a clear instruction manual? These are all good signs that you’ll be able to master the programming process.

If your schedule is different from day to day, consider looking for a feeder that connects to Wi-Fi. With a more technologically-savvy feeder, you can set feeding times on the fly using an app to ensure that your fish are always fed at the right time.

Benefits of an Automatic Fish Feeder

Fish are relatively low-maintenance pets. As long as you keep their tank clean and feed them enough, they stay happy and healthy. When it comes to feeding, however, the requirements can be stringent. Too much food causes the waste levels in the tank to become toxic to fish. Too little, and the fish won’t have enough nutrients to survive.

What does that mean for you? If you can’t feed the fish on time, you run the risk of underfeeding them — or, you need to find family and friends to feed them for you.

That’s where an automatic fish feeder has big benefits, both for you, your loved ones, and your fish. These feeders take the hassle out of timing meals. All you need to do is set when the food will be released and the feeder does the rest. Since fish have delicate digestive systems, these feeders also allow you to set precise portions.

Final Verdict

A great automated fish feeder will make your life considerably easier and eliminate worries while you're away from your fish. By choosing a model with the features you need, you can keep your fish happy and healthy, whether you're home or away.
