Review of the Best Automatic Fish Feeder (FAQs)

Just like many other products online, there are certain factors you must consider when choosing the best automatic fish feeder for yourself;

Question: Which type of automatic fish feeder should I go for?

Answer: There are two types of automatic fish feeders you can find, these are; Rotating barrel fish feeders, and portion-controlled fish feeders. The rotating barrel fish feeders come with the simplest designs and they normally rotate at up to 360 degrees to release food into your tank. The amount of food released into the take will depend on the hole size of the barrel but you can control how big the food hole on the barrel should be.

This type of barrel holds more food than the portion-controlled, hence they may be the ideal option if you are traveling for a very long time. There are some models of the barrels feeders that can hold up to 6 weeks of fish feed.  

The issue with barrel automatic feeders is that they often come with one compartment which can be unsuitable for community aquariums and they may not disperse food evenly when you feed them with multiple kinds of feed.

If you want to mix flakes and pellets, for instance, a barrel feeder may release too many flakes with fewer pellets, which means the bottom-living fish species may go hungry because they consume pellets more than flakes. For this reason, barrel automatic feeders are more efficient for just one type of fish food. You should also avoid using this feeder for larger, dried foods because some can block the opening of the barrel.

On the other hand, portion-controlled fish feeders will allow you to control the amount of food you introduce into the fish tank at any given time. It is more suitable for those on a budget, who want to ensure that their fish pets are no over-fed.

The portion-controlled automatic feeder comes with arranged trays and you will fill each tray with the food you want to release into the tank at a time and you set the timer. At the feeding time set on your timer, all the contents in one tray will be emptied into the tank. For this reason, you can use one tray for pellets, and another for powder feeds or flakes.

With the portion-controlled feeder, you can measure each type of feed and then mix them ensuring that the top, middle and bottom fish dwellers get the right quantities of food they deserve. Most models of these feeders come with 10-14 different compartments and you can feed your fish even if you are traveling for up to 14 days.

Question: What type of installation should I go for?

Answer: The type of installation you go for will depend on the size of your tank. Some installation options are suitable only for small and medium aquariums, others are only suitable for larger tanks. You must choose an automatic feeder that will comfortably sit on top or side of your aquarium.

Most models of automatic feeders come with brackets that make it easier to mount them outside of the aquarium. Some models do come with suction cups to mount the feeder at the top and sides of the fish tank.

For convenience sake, the options of feeders with mountable brackets will help you clean and measure your fish food better without contaminating the water in the tank. Though this does not mean the feeder that relies on suction cups for installation will automatically contaminate the fish water, you have to consider the risks of making errors, especially when adding the food.  

When mounting the automatic feeder, you must position the device in such a way that it does not come in contact or interfere with the functioning of other equipment like aerators.

Question: What other factors do I need to consider when choosing an automatic fish feeder?

Answer: The power source of the automatic feeder is another key consideration. Some feeders can be powered directly from electric sources, and others rely on rechargeable AA batteries. Some products do come with AA batteries included, and for some products, you have to buy the rechargeable batteries separately.

In places where public electricity supplies are stable, you should opt for electrically powered automatic feeders and in places where electricity supply is intermittent, you should rather go for the feeders with rechargeable batteries.

You must follow the instructions that come with the manual when installing your automatic fish feeder. Doing this will help prevent higher risks of errors. It is also important that you test the timer before using it fully in feeding your fish. You may also want to consider automatic feeder manufacturers who offer moneyback guaranty and limited warranties on their product. An ideal manufacturer must offer a reliable customer care support online, to help you deal with any technical or non-technical issue with your automatic feeder. For convenience sake, you should also consider a product that is made of durable material that can withstand moisture and other adverse weather conditions.


While budgeting is very important when it comes to buying automatic fish feeders, you must not be lured away by ridiculously low prices. You should consider top quality design and functionality over any other factor. It is quite common to see some beginner users of automatic feeders to buy products that are too large or too small for their tanks. You need to pay attention to the tank size requirements before you purchase the feeder. Many automatic fish feeders come at varying sizes of 100-200 ml. This is the amount of food they can hold at a particular time, and the larger the size, the bigger the tank size requirements.
