Every aquarium needs some equipment to keep your fish healthy – common ones include: a filter (to clean the water) and a heater (to warm it up).
Automatic fish feeders are electronic devices that feed your fish when you are not around. You can control the portion sizes and the frequency of meal times.
They are effectively a container of food that runs on a timer, dropping food into the water at the programmed time.
Depending on the model, they can run for six weeks without having to be refilled.
Most are plastic with a clear container and a digital screen for you to program the settings. Some look slightly different because there is more than one type of automatic feeder (more on this later), but they usually sit on the side of the aquarium.
They can be used in any type of tank: cold-water, tropical and marine.
If you keep fish in a pond, there are models out there for you too.
Even the fishing industry uses them.

How Does an Automatic Fish Feeder Work?
Automatic fish feeders sit on the side or the top of the tank, releasing food at intervals and portion sizes decided by you.
They have three main parts: a hopper, a timer and some method to set the portion sizes and time intervals.
The hopper is the part that holds the food, you fill it up and the food will gradually be removed. The timer rotates the hopper, dispensing food in the process. They can be powered by either batteries or power cords, depending on the model you buy.
Some devices will have suction cups to sit on the inner wall of the aquarium, others have mounting brackets that hook over the side of the tank.
Certain models have a ‘feed now’ button. This drops food into the tank outside of the programmed times. It is helpful for testing that the feeder is working without waiting for the programmed time to come around.
New designs are making it possible for feeders to be controlled from your phone also.
They need to be maintained, but this isn’t too difficult. Clean the device when you clean the tank. Replace the food too, and make sure everything is dry to prevent it malfunctioning.
Remember, with an auto feeder you will only be able to use dried foods in your feeder. If your fish enjoy live or frozen foods (like bloodworms), perhaps you could switch to freeze-dried foods.
How to Choose an Automatic Fish Feeder?
The amount of time you are going to be away will influence your choice. If it’s just for a few days, then you can use a portion control fish feeder. If you are away for a few weeks at a time, you will need a rotating barrel.
You must also consider which foods your fish need. If you have a community of fish that need different foods, then you are better off with a portion control feeder so that the required food is getting to everybody.
Larger foods will need a portion control feeder too.
What are the Different Types of Automatic Fish Feeders?
There are two common types of auto fish feeders. They both produce the same result but they operate slightly differently.
Rotating Barrel Fish Feeders
These are the most common types and they have the simplest design.
At feeding time, the barrel rotates and releases food into the tank. The amount of food released is determined by the size of the hole in the barrel, but you have control over how big the hole is.
This type of feeder holds the most food, so it is great for people who are going away for extended periods of time – some models can hold six weeks worth of food.
However, rotating barrel feeders only have one compartment which can cause problems for community aquariums. You can fill the barrel with multiple types of food, but you can’t be sure that they will be dispensed evenly.
For example, maybe you want to mix flakes and pellets. Too many flakes could be released compared to pellets and your bottom-dwelling fish might then go underfed. Choosing just one food type with these feeders.
Larger dried fish foods should be avoided – algae wafers and sticks can block the barrel opening.
Portion Control Fish Feeders
As the name suggests, you get great control over how much food enters your tank with these feeders.
They have a circular arrangement of trays. You fill each tray with the food you want to be released to the tank at one time, you then set the timer. At feeding time, the entire contents of one tray is emptied into the tank.
You can measure out each meal and mix different food types (even larger dried foods) ensuring everyone gets the right amount of the food they need. This is ideal for community aquariums.
The main problem with portion control feeders is that they hold less food, so you can’t be away as long. Most models have 10-14 compartments which is 10-14 days worth of food.
How to Set Up an Automatic Fish Feeder
Automatic fish feeders can be added to your tank at any point – even after you’ve set the tank up.
Position the feeder away from the other equipment in your tank so that the food does not interfere with anything once it’s released.
When you’ve decided on the location, you need to mount it. The way you do this will vary depending on the model you have. Most come with brackets for you to mount the feeder on the outside of the tank, others have suction cups to sit on the inside of the aquarium.
Next, add the power supply (either batteries or a cord).
Now you can fill the feeder with food. Use the buttons around the digital screen to adjust the settings. You should have the option to control portion size and frequency (for most people this is once or twice a day).
If your device has a ‘feed now’ button, use this to test that everything is working smoothly. If not, make sure you are around at the first programmed feeding time to check it’s working.
Automatic feeders save you time and can get you out of trouble if you have nobody else to step in at feeding times when you are away.
However, you need to get the right model for your situation.
Once you have found the right feeder, it is easy to set up and operate. You can leave it to do its job without a worry.
