Automatic Fish Feeders for Aquariums Buyers Guide: What to Look Out For

There are a few important factors that you need to keep in mind when choosing an automatic fish feeder.


Always pay attention to the capacity of your automatic fish feeder, as this will determine how big of a fish tank it is ideal for it. As you can tell, most regular units feature about 200 milliliters of capacity.


Any automatic fish feeder worth its money absolutely needs to be fully adjustable. You should be able to adjust how many times the drum rolls per feeding, the interval of the feedings or how many feedings per day there will be, and how much food is released with each feeding. There should be a precise adjustment mechanism for all of these vectors.

These automatic fish feeders sit right on top of aquariums, so they need to have a moisture proof design. Being impact resistant is helpful as well.

Power Source

Of course, it’s always nice when a unit can function using batteries, but having a dedicated power source has its advantages as well, so consider this carefully.
