Model 3581 Eheim Everyday Fish Feeder Review

The Eheim everyday fish feeder (model 3581) is a very popular product that is rated very highly, not just in the USA but worldwide.  We all know that reviews don’t lie, as most reviews are from happy customers that are verified purchasers of the product.


The feeder works in a standard way by rotating a drum containing the fish food, allowing it to be automatically sprinkled out.  Portion size is controlled by the doors position so the right quantity is always dispensed.  It is most commonly used in aquariums and terrariums.

Eheim Everyday Features

Here are some of the awesome features:

  • The timer is versatile and can be set by the user to feed 1 to 8 times per day.
  • For every meal you can choose whether to do a single or double portion, which is either one turn of the bin or two turns.
  • It can dispense any kind of dry fish food including granules and flakes.  You also have full control over how much food is dispensed by adjusting the door to open or close more.
  • You don’t need a power cord as the unit is powered by 2 AA batteries and the battery can last for up to 6 weeks
  • A digital timer and display make for easy programming.
  • The food in the bin won’t stick together and jam the opening because there’s a built in fan that keeps the food dry.

  • Buttons are splash proof.
  • Special indicator warns for low battery.
