If you have an upcoming trip, whether it’s for a few days or weeks, then you’ve likely been looking into options to make sure your fish are cared for while you’re away. In lieu of having someone check on your fish while you’re gone, an automatic fish feeder is a great option to make sure your fish are taken care of.
But making sure the automatic fish feeder you choose will work as expected is extremely important, especially if nobody will be able to check in on your aquarium.

Buyer’s Guide
What to Consider When Choosing the Right Automatic Fish Food Feeder for Your Tank:
How Long You’ll Be Away: Some automatic feeders will be able to feed your fish for weeks if needed! If you’re planning a long trip, then you’ll want to make sure you’re choosing a feeder that will hold enough food and battery power to feed the entire length of time you’re gone. Some feeders are better for daily or short-term use, making them better choices for weekend trips or even routine feedings to take a task off your plate.
How Many Fish You’re Feeding: A tank with six large goldfish is going to require much more food than a tank with a dozen neon tetras. A good way to determine how much food you’ll need your automatic feeder to hold is to keep a log of how many times per day you’re feeding your fish and how much each time.
How Often You’re Feeding: How many fish you’re feeding isn’t the only considering when it comes to how much food you need your feeder to hold. If you want your fish fed four times per day, then an automatic feeder with once or twice daily settings isn’t going to meet your needs. You want to find an automatic feeder that will feed your fish the correct amount at intervals they are used to. The last thing you want is to overfeed your fish while you’re away and come home to a mess with your water parameters.
What Type of Food You’re Feeding: If you’re feeding koi, then you’ll need to ensure that your feeder can distribute the koi sticks that you’re feeding. If you’re feeding small fish, then you’ll need to ensure that your feeder can feed small food like powder, flakes, or baby pellets. Not all feeders are going to evenly distribute all types of foods.
What Your Tank Setup Is: If your tank has a hood, then you’ll need to find a feeder that can work with a hood or you’ll need to find a way to rig a feeder. If your tank is acrylic, then it will be able to hold different weight than glass but will be more likely to scratch from the use of adjustable mounts. Knowing your tank’s materials, thickness, and whether it has a rim or not will help guide you in choosing the right automatic feeder to meet your needs.
What Options Do You Have When Buying Automatic Fish Food Feeders?
Direction: Some feeders mount over the rim of a tank or over the glass of a rimless tank, while others can be mounted on top of a lid or hood and some may even be able to be installed on the underside of a lid that is far enough away from the waterline.
Power source: Most automatic feeders are battery-powered, but some have the ability to be plugged into a USB or an outlet. A plug-in feeder will not run out of power but is subject to reset during a power outage and obviously takes up outlet space. Battery-powered automatic feeders are effective but need to be monitored closely to ensure the battery stays fresh or charged to keep the feeder in working order.
Ventilation: Some automatic feeders have built-in ventilation systems that work to keep food fresh and dry. Some feeders do not have this feature but are made to be water-tight and do not allow for moisture to get inside of the food hopper. Other feeders have the option to connect external air pumps to provide airflow into the feeder to keep food fresh.
Size: Based on how many fish you’re feeding, how long you’ll be away, how frequently you’re feeding, and what type of food you’re feeding, you could need various sizes of feeders. Some feeders only hold enough food for a few days or only hold small food, while others hold enough food that they are impractical for anything other than feeding large fish or many fish.
Number of feedings: Automatic fish feeders can feed anywhere from 1-5 times per day. Knowing how many times per day you want your fish fed will help you pick the right feeder.
Setup: Some automatic feeders have digital displays and can have simple to complex setups. Other feeders don’t have digital displays, but some can still be confusing to get set up correctly.
Picking an automatic fish feeder for your aquarium can be a high-pressure task. You want to have peace of mind in the product you choose, so use these reviews to help you pick the best product for your aquarium. Once you’ve picked an automatic feeder, try it out for at least a few days before you plan to be away, so you know it’s fully functional and set to your fish’s liking.
