Buyer's Guide


  • How Long You’ll Be Gone: If necessary, some automated feeders can feed your fish for weeks! If you’re going on a lengthy journey, you’ll want to get a feeder that has enough food and battery power to last the entire time. Some feeders are more suited for daily or short-term use, making them a better option for weekend vacations or even routine feedings.
  • A tank containing six huge goldfish will require far more food than a tank containing twelve neon tetras. An excellent technique to assess how much food your automated feeder will need to contain is to keep track of how many times each day and how much you feed your fish.
  • How Often You Feed: The number of fish you feed is not the only factor to consider when determining how much food your feeder should store. If you wish to feed your fish four times per day, an automated feeder with once or twice-daily settings would not suffice. You need to choose an automated feeder that will feed your fish the appropriate amount at normal intervals. The last thing you want is to overfeed your fish while you’re away and return to a water quality disaster.
  • If you are feeding koi, your feeder must be able to evenly spread the koi sticks that you are feeding. If you are feeding little fish, your feeder must be able to accommodate small foods like powder, flakes, or baby pellets. Not all feeders will distribute all types of food uniformly.
  • What Your Tank Setup Is: If your tank has a hood, you will need to find a feeder that is compatible with hoods or devise a technique to rig a feeder. Acrylic tanks can support greater weight than glass tanks, although they are more susceptible to scratching when using adjustable mounts. Knowing your tank’s materials, wall thickness, and whether or not it has a rim can assist you to select the appropriate automated feeder for your needs.

What alternatives are there when purchasing automatic fish food feeders?

  • Others feeders may be put over the rim of a tank or over the glass of a rimless tank, while others can be set on top of a lid or hood, and some can even be fitted on the bottom of a lid that is far enough from the waterline.
  • Most automated feeders are powered with batteries, although some may also be hooked via a USB port or an electrical outlet. A plug-in feeder will never run out of electricity, but it may need to be reset after a power outage, and it clearly requires an outlet. Automatic feeders that are powered by batteries are successful, but they must be regularly checked to ensure that the battery remains fresh or charged to maintain the feeder operational.
  • Some automated feeders are equipped with ventilation systems that function to keep food fresh and dry. Some feeders lack this function but are designed to be watertight and prevent moisture from entering the food hopper. Other feeders provide the option of connecting external air pumps to supply airflow into the feeder in order to maintain food freshness.
  • Depending on how many fish you’re feeding, how long you’ll be away, how often you’ll feed, and what sort of food you’re feeding, you may require feeders of varying sizes. Some feeders can only contain enough food for a few days or can only hold tiny food, but others can hold so much food that they are unsuitable for anything other than feeding huge or many fish.
  • Automatic fish feeders may feed anywhere from one to five times each day. Knowing how frequently you wish to feed your fish will help you choose the appropriate feeder.
  • Some automated feeders include digital screens and basic to complicated configurations. Other feeders lack digital screens but might still be difficult to accurately configure.


The Eheim Everyday Fish Feeder is the best overall product based on its high functionality and user-friendliness, however, for a more premium product, the Current USA 3860 Aquachef Automatic Fish feeder has the most features and the most user-friendly design. The Penn-Plax Daily Double II Automatic Fish Feeder offers the best value due to its low price and user-friendliness.

Choosing an automated fish feeder for an aquarium may be a stressful endeavor. You want to have confidence in the thing you buy, so utilize these reviews to select the greatest item for your aquarium. Once you’ve selected an automated feeder, test it for as least a few days before leaving, to ensure that it is completely working and configured to your fish’s preferences.
