What To Look For In A Good Automatic Fish Feeder

Automatic fish feeders can make your life a whole lot easier when it comes to feeding your fish. But with so many options out there, you may not know where to start. By considering reliability, capacity, ease of use, maintenance, power source, and build quality, you’ll find the perfect one for your needs.


When choosing an automatic fish feeder, reliability is key. You want a feeder that you can count on to do its job consistently. So, look for models with a reputation for dependable performance. After all, you don’t want to end up with a feeder that lets you down and leaves your fish hungry.


Consider the capacity of the feeder. How much food can it hold? This is important, especially if you have multiple fish or if you’ll be away for an extended period. You want to make sure the feeder can provide enough food to keep your fish happy and well-fed while you’re away.

Ease of Use

Nobody wants a complicated setup or confusing instructions. So, look for an automatic fish feeder that is easy to use. Find one with a user-friendly interface and clear instructions that make setting it up and programming it a breeze. 

Of course, the last thing you want is to spend hours trying to figure out how to get it working.


Cleaning the fish feeder shouldn’t be a hassle. Choose a model that is easy to disassemble and clean. Look for feeders that are designed with maintenance in mind. This way, you can keep your feeder clean and functioning properly without much effort.

Power Source

Consider the power source of the automatic fish feeder. Some feeders run on batteries, while others need to be plugged into an electrical outlet. Battery-powered feeders offer flexibility in placement, without worrying about cords. 

Electric feeders tend to be more reliable, ensuring a consistent power supply. Choose the option that suits your needs and preferences.

Build Quality

Invest in a fish feeder that is built to last. Try to look for models made from high-quality materials that can withstand being near water. Choosing a well-built feeder ensures longevity and saves you from having to replace it frequently.

What Are The Different Types Of Automatic Fish Feeder?

There are a few different types of automatic fish feeders available on the market. Let’s explore two common types:

Rotating Barrel Fish Feeders

Simple Design: Rotating barrel fish feeders have a basic design. They usually have a round container that holds the fish food. The container spins to release the food into the tank.

Adjustable Rotation Settings: These feeders let you change how often they rotate. You can set them to spin at certain times, like once or twice a day. This allows you to decide when your fish get fed.

Reliable Food Dispensation: The spinning mechanism in these feeders ensures that the food comes out smoothly. It prevents clogs and makes sure the food keeps coming out steadily for your fish to eat.

Portion Control Fish Feeders

Precise Portion Sizes: Portion control fish feeders give you exact amounts of food for each feeding. They have separate compartments that hold specific portions. This helps you avoid giving your fish too much food, which can cause problems.

Adjustable Feeding Intervals: These feeders let you choose how often they dispense food. You can set them to release food at different times during the day, helping you establish a regular feeding schedule.

Prevents Food Waste: By giving out measured portions, portion control feeders reduce the chances of wasting food. They make sure only the right amount of food gets released so you don’t end up with excess food sitting at the bottom of the tank.

Customizable Feeding Schedules: Some portion control feeders allow you to personalize the feeding schedule. You can program different feeding times and portion sizes for specific days. This is useful if you have different types of fish or if you want to mimic their natural feeding patterns.

What Food Can You Put In Your Automatic Feeder?

When using an automatic fish feeder, it’s important to know what types of food you can safely use. Not all foods are suitable for automatic feeders because they can get stuck or spoil quickly. Here are some common fish foods that work well in automatic feeders:


Flakes are a popular choice for many fish. They come in different varieties for different diets. Flakes are easy to dispense and won’t clog the feeder.


Pellets are another common option. They come in different sizes and formulas for different fish. Pellets work well in automatic feeders because they are easy to dispense and provide a balanced diet. 

Additionally, some fish, like bettas, prefer slow-sinking or floating pellets. If you want to use these pellets, make sure your automatic feeder is designed for them. You don’t want them to get stuck or cause any issues.


Granules are similar to pellets and work well in automatic feeders too. They have a mix of ingredients that many fish enjoy. Generally, you can dispense granules without any problems.


Depending on the model and the portion size, freeze-dried foods like bloodworms, brine shrimp, or daphnia can be used in automatic feeders. Just make sure the feeder can keep the food dry and fresh. Also, make sure to store these foods in sealed containers to maintain their quality.

How Much Food Should You Put In Your Automatic Feeder?

Knowing how much food to put in your automatic feeder is important for keeping your fish healthy. Here are some things to consider:

Fish Type

Different fish species have varying dietary requirements. Some fish are small and have slower metabolisms, while others are larger and more active. Research the specific dietary needs of your fish using the fish guides on this website to determine the appropriate portion size.

Avoid Overfeeding

Overfeeding can lead to various issues, including poor water quality and health problems. And remember, it’s better to slightly underfeed than to overfeed your fish. So, start with a small amount and see if they finish it within a few minutes.

Consider Feeding Times

Automatic feeders can be set to dispense food multiple times a day. If you choose to feed your fish multiple times, divide the total daily amount of food into smaller portions. This helps prevent overeating and promotes a more natural feeding pattern for your fish.

Monitor Fish Behavior

Pay attention to how your fish eat. If they eat everything quickly, the amount is probably right. If there’s still food after a few minutes, reduce the amount so they don’t waste it.

Make Adjustments  

It may take some trial and error to find the right amount of food for your fish. Regularly monitor their condition, growth, and behavior. If your fish appear too thin or lack energy, slightly increase the portion size. If they’re getting chubby or the water quality becomes bad, decrease the amount of food.
