Benefits Choosing an Automatic Fish Food Feeder

1. No More Overfeeding

I get it:

It’s really easy to accidentally overfeed your fish.

After all – who can resist their adorable antics?

An automatic aquarium feeder can eliminate this tendency and keep your fish from getting overfed – and the tank from being fouled.

2. Safer Vacation Feeding

Are you someone who travels frequently?

If so, “Who is going to feed the fish?” might be one more question you’re stressing about.

Automatic aquarium food dispensers can be the answer.

Dissolving tablets can foul your water while you’re away, even to the point of messing up your water quality.

When you aren’t there to remedy the situation…

… You can come home to a tank of dead fish.

It’s not the first horror story I’ve heard about these.

So you can get a pet sitter…

… But it can be tricky getting them to feed the proper amount.

(And they could forget!)

Harnessing technology to consistently deliver the right amount of food each day is also more cost-effective.

3. Lighten Your Workload

Some fish – especially young, growing ones – need to be fed more than one time per day.

Even if you only have to feed one time a day…

… That’s still one more thing to remember.

And let’s face it:

Most of us are pretty busy people with enough on our plates already.

And the less work fishkeeping is, the more enjoyable it is.

80% of fishkeepers quit the hobby after two years because of one reason and one reason only:

Too much work.

Automating the feeding is one way to take a chunk out of your responsibilities and lighten your workload.


  • Test the auto feeder out for at least a week before leaving on vacation to ensure it is dispensing the right amount
  • Understand how the feeder of your choice is attached before you purchase it to save hassle. Some do not fit on rimless aquariums, while others need to be propped up or overhanging a lid.
  • Flakes that are too large to be dispensed correctly can be slightly crushed before being added to the cartridge.
  • Condensation or moisture of any kind inside the cartridge can cause the food to stick and not dispense properly. Ensure your feeder has a way to compensate for this, such as a vent, fan or trap door.
