Features to Look out For When Choosing an Automatic Fish Feeder

Let’s start this article by putting automatic fish feeders under the microscope. The wide range of models currently on the market can be quite intimidating – so what should you look when when trying to decide which model is best for your purposes?

Food Dispenser Technique

Automatic fish feeders may be available in a variety of designs, but there are really only  two main types. The key difference between these types is how the fish food is actually dispensed into the water.

The first type of automatic fish feeder utilizes a rotating barrel and is the most common. The fish food goes into the barrel, which rotates as per the timer and drops a small amount of food into the aquarium. You can control the opening of the barrel to ensure the correct amount of food is dispensed.

Automatic fish feeders that employ the barrel design can hold a larger amount of food than other feeders. This can be helpful for vacation time, when you may want o feed for fish for some weeks while you’re away.

However, there’s one major issue with this type of automatic feeder. If you’ve more than one type of fish in the aquarium with different dietary requirements, then it becomes difficult to feed all of them simultaneously. You will essentially need a rotating barrel fish feeder for each type of fish.

The second type of fish feeder gives you complete control over the portion of food to be dispensed. You might say it resembles a pillbox with multiple small containers or trays. You fill these with the exact amount of food that your fish require.

If you have multiple fish in your aquarium you can fill up successive containers with specific foods for each of them and set the timer to dispense the contents of the containers at different times in a day to ensure all your fish are fed properly.

The drawback of this type is that the total amount of fish food you can load up isn’t a lot. So, at least every couple of weeks you will have to repeat the process.

Manual Release Button

Irrespective of which food dispensing technique matches your requirements, you should buy an auto fish feeder with a manual release button. This button lets you dispense food outside of the programmed timings. It’s important because it allows you to test the device to ascertain that the right amount of food is being dispensed.

Multiple Feedings

The importance of this feature depends entirely on your preference as well as the dietary requirements of your fish. So, if you like feeding your fish multiple times in a day then look for a fish feeder that offers such a feature – not all do.

Built-in Memory

If your automatic fish feeder doesn’t have a built-in memory, then every time you replace batteries the programmed feeding times will be reset to default and you will have to reprogram them. This might not seem like a major cause for concern, but it will feel like an unnecessary nuisance when you do have to reprogram the feeding times multiple times. So, ideally select an auto fish feeder that has this feature.
