Benefits of Installing The Best Automatic Fish Feeder 

Best automatic fish feedersWhen all is said and done, the most important thing in maintaining the health of your aquarium fish is actually feeding them regularly! I know I don’t like to skip a meal, and fish are the same.

With an automatic fish feeder you can simply relax and enjoy your tank and know that all your fish are happy swimming with full bellies. And when you go on holidays you don’t have to find someone or call in any favors to make sure your prized fish are fed. 

That advantage is imminently obvious, but others are somewhat harder to spot. As in anything, before buying a new gadget it’s important to understand what you are buying. So what exactly are the advantages of having the best automatic fish feeder for your tank? 

  1. All the settings are pre set, so you don’t have to worry about portioning the food, or the timings of the feedings. Depending on the model you choose you can choose to feed your fish up to four times a day. You can base this decision on the needs of whatever fish you keep. 
  2. Once you have everything set up you will end up saving a lot of time and money. Installing the best automatic fish feeder for your tank saves you time having to feed your fish twice every day, so you can relax and just sit back to enjoy your aquarium. You will end up saving money on fish food as you will be cutting out a lot of waste. 
  3. Having less wasted food is good not only for your pockets, but for the aquarium too. Feeding your fish too much will mean bits of food go uneaten and will fester in the tank, causing algal and bacteria growth and will make your water cloudy. Less wasted food will mean you avoid having food go bad in your aquarium and cause these unwanted issues.
  4. You will be able to set up your best automatic fish feeder with a container of food and portion it so that you can be sure that you don’t need to adjust it for one week, or two weeks, or however long you need. This means that when you go on holiday you can relax and know your fish will be fed on time and get the right amount every day.

How Do Automatic Fish Feeders Work?

An automatic fish feeder is either a battery operated or mains powered. Battery operated models mean you don’t need to worry about cords and electricity and water mixing, whilst mains powered models give you peace of mind as they will never stop running as long as there is power. 

The automatic fish feeder will have a container that you fill with food. Some can handle all fish food types while others may struggle with certain types of food. Different models will have different sized food containers depending on the size of aquarium they cater for.

You will be able to program the feeder to release food at set times. Some models allow you to set specific times up to four times a day, while some others allow for a pre-set delay between feedings. You will also be able to control the portion sizes by controlling how much food leaves the container each time, or how many times the container rotates to release food.

How Should You Choose an Automatic Fish Feeder?

There are a number of factors you should take into consideration whilst looking at which automatic fish feeder to purchase. 

The size of the food container should be a primary concern. As common sense would have it, if you have a small aquarium you should get an automatic fish feeder with a small container, and a large aquarium would require a big food container.

If the container is too small you will run out of food quickly, and will have to keep refilling. If you are going away on holiday for a longer period this may cause an issue!

Similarly if the food container is too big for the size of your aquarium you may find that it releases too much food per feeding and overfeeds your fish. This can be as bad as underfeeding, and can lead to unhealthy fish and a build up of algae and bacteria in the water.

It is better to feed your fish smaller amounts more regularly throughout the day. Whilst this is not a be all or end all, it is generally more healthy to have the smaller more regular feedings. 

Considering this it is better to have an automatic fish feeder which can dispense food more often throughout the day. But consider this in relation to the other aspects as well. 

Having a battery indicator may not seem like it will be important at all, but it can actually be a bit of a life saver. It will show you how close you are to running out of power, and when you need to recharge or replace batteries. You only need to run out of power once whilst away on vacation to know how useful this is!

You should also consider if purchasing the best automatic fish feeder for your tank will be worthwhile. If you work from home for instance and like feeding your fish and walking them swim and eat then there’s not much point! However if you have a busy working life or are planning a vacation then one will be perfect for you so you can worry about one less thing. 

A common problem that can occur with automatic fish feeders is the food getting moist and either clumping so it causes dispense problems or spoiling. Many feeders are moisture resistant, or are sealed to prevent moisture from entering. The Eheim Automatic Fish Feeder Unit even has an integrated fan and ventilation system which keeps the food dry and actually actively draws moisture out of the food container.

How Do You Setup an Automatic Fish Feeder?

The first thing you should do before setting up and getting going using your new automatic fish feeder is to inspect it for damage. There shouldn’t be any, but especially with the cheaper models you never know if something has become cracked in transit. 

The useful thing about buying through amazon is that you can just send it right back if there is an issue and a new one will be sent to you, so don’t worry too much if you do find a problem, it’s just a bit of a pain.

Once you’ve checked for damage then either connect the feeder to the mains, connect the battery to start charging, or insert the required batteries. Once you’re powered up you can start to play around with the LCD screen. Read the instructions which will tell you how to set up the feeder correctly to dispense food at the times you need.

Before you put food into the container give it a good clean out and then let it dry thoroughly. This step is important, as the feeder has just been in the post, so you want to ensure it is clean before you use it to feed your fish. Make sure it is bone dry before putting food into it, as moisture and cause the food to clump up and block the dispense, or cause the food to go mouldy.

Next is to adjust the amount of food your fish will receive each feeding. Lots of automatic fish feeder models will have an adjustable hole on the food container which you can make smaller or bigger depending on how much food you want released. 

There is a little trial and error involved normally in getting the perfect amount of food each feeding time. In general it is recommended to release the amount of food that can be eaten in about 10-15 seconds. Play around with it a little and make sure you don’t under or overfeed your fish! 

If you can try and install your automatic fish feeder on the opposite side of your tank to your filter inlet. The last thing you want is for the food to go straight into the aquarium filter and clog it up! HOB filters are most likely to have this issue as their intakes are nearer the surface than canister filters.


If you decide that having the best automatic fish feeder will be beneficial to your aquarium (which most likely it will be!) then any on this list will serve you and your fish well. We know how important your fish are to you, so any of these feeders will give you peace of mind when it comes to giving your fish their well deserved food!

These units can work for most larger and nano saltwater fish, as well as freshwater fish, so they are most likely suitable for whatever aquarium you have.
