How to Choose Automatic Fish Feeder for an Aquarium

Having a pet means you have to keep your eyes on it. In case of business trips or vacations, we cannot look over the fish tanks. We change the water and clean the substrate and the filters  before going on vacation.

But what about the food? Is it okay to use an Automatic Fish Feeder? Will it give the exact quantity of food and on time? How to choose an automatic fish feeder for your aquarium? Let's read this article together and find out the answers.


What is an automatic fish feeder and how does it work?

Pet fish are always concerned when we are not at home or on vacation. That is where an automatic fish feeder helps us.

An automatic fish feeder is a mechanical tool operated by a battery that gives food to your fish in exact quantity and at the right scheduled time.

This small tool plays a great role in your absence and can also give food multiple times a day as we set a timer. It is easy to operate and also available at very affordable prices. So, how does it works?

It works on a simple principle. We have to set a timer, for example, if we choose 10:00 am in the morning, then when the time arrives the motor will automatically start and rotate. The food we already filled in the food collector box will release in a fixed amount (we have to set the quantity) and it releases through a window to the output slot, which later falls into the fish tank water.

Some feeders show mechanical disturbances that lead to miss feeding, overfeeding, and no feeding. Not all automatic feeders can feed all the species, so the type of feeder depends upon the specie of fish. In order to choose the best, we had to know about the products and their features.


What are the steps to setting up an automatic fish feeder?

In order to set up an automatic fish feeder first, we have to select a location then we move to the setting up the time and foods. Any of the locations is best for the fish feeder machine we have to just make sure that while the food drops the splash or droplets of water will not bounce back to the machine because that will create moisture which later spoils the food or may start smelling.

After getting the proper position, here the installation starts. Different products have different installing steps. “Hygger Automatic Fish Feeder” in our store came up with a screw, after tightening it we can lift the slider then fix the lid and adjust the feeder’s nose.

Lastly, connect the feeder with the plugin wire. Then it is ready to set the timer and the quantity of food to dispense in an automated way. Please make sure to avoid larger food like wafers or flakes, either you can crush them or used 4-10 mm pellets.

  • Dry food: we can choose the food which can floats in water like pellets, flakes which are having low fiber with vegetable food pieces.
  • Frozen food: It contributes like bloodworms, prawns, mussels, or shrimps. For herbivores, we can use spirulina (Frozen). Some people also use dried nutritious food like tubifex worms.
  • Live food: This includes live worms, crickets, brine, or shrimps.
  • Greens vegetables: This includes cucumber, spinach, zucchini, and lettuce. (*Note: Always use fresh green foods and clean the left food particles from the fish tank over substrates and filter area.)


How do you know if an automatic fish feeder is right for your fish?

Apart from the benefits, there are some drawbacks too that later created problems in maintaining a suitable environment.

Most of the time some cheap fish feeders don’t have a ventilation system and also don’t prevent themselves from dropping or a splash of water, in both cases food gets moisture that spoils the food and also starts smelling.

If the food dispenser tray or the output slot gets damaged then the unbalanced food drops off each time which leads to overfeeding or no feeding which creates a serious impact directly on their health.

Sometimes the machine itself falls off in water or outside and gets damage that breaks then the return policy or guarantee both not considered which makes a loss to fish owners.
