Automatic Fish Feeder

According to a survey made in 2017 and 2018 by the American Pet Products Association approximately 12.5 million American households own freshwater fish while a lower number of households, 2.5 million, own saltwater fish. The total number of freshwater and saltwater fish held in the U.S. is 39.3 million and 18.8 million, respectively. The statistics also show that fish are currently the third most popular pet in America. There are many reasons why people get fish as pets, including the fact that some species are easy to care for. All you need to do is to properly maintain the aquarium or tank and feed fish regularly.

Once feeding per day is enough for keeping your fish healthy but some people prefer feeding them twice a day, or even more frequently. Anyway, no matter what is your feeding schedule, the most important aspect is to avoid overfeeding. Although feeding fish by yourself is not a demanding task, many people opt for an automatic fish feeder. This is a smart device that dispenses food by following a particular schedule. So, you can choose when exactly you want fish to be fed and the device will dispense food automatically. One of the main advantages of having a fish feeder is the fact that you can go on vacation without asking your relatives or friends to feed your fish. In case you’re interested in buying an automatic fish feeder, take a look at these 5 models selected by us.

This fish feeder is also made by a popular brand. Fish Mate offers innovative fish-care solutions to all those who want to take advantage of technology. It is suitable for small to medium-sized aquariums and we recommend it if you have just a few fish. As you will see, the device is slightly different in comparison to the other ones, reason for which is one of the most well-liked feeders.


Instead of having a rotation drum, this model incorporates a food container with multiple trays. It has no buttons, just a quartz timer and 4 little red pegs to set the desired meals.

The food container features 14 trays where you can add the food you want. It works with multiple fish food and the best thing is that you can combine two or more types of food in the same tray. At mealtime, the container rolls around and dispenses an entire tray, but gradually, over a period of 2 hours. The timer allows you to set up to 4 feedings at intervals selected by you. Unfortunately, it has no manual release button or slider to adjust the amount of food. But in this case, you don’t really need a slider as you can control the amount of food when adding it in the trays. Also, it lets you know when it’s time to replace the battery, so there are no chances for the device to stop working.

  • Precise food amount: you can add the exact amount of food in each of the 14 trays. You can even measure out food proportions and give your fish the exact amount of food recommended for their species.
  • Promotes a Well-Balanced Diet: due to the fact that it has individual trays for each meal, you can mix more types of food. Also, you can alternate the food by adding one type in a tray and a different one in the following tray. As a result, your fish will eat a different meal each day.

Although it has some minors drawbacks, the device works surprisingly well. The food trays are rather small, so it’s not the best option if you have more fish. It is the only model that allows you to diversify diet and to measure out each meal. Also, it comes at an affordable price.
