We love our pets so much that we are constantly looking for ways to enhance their lives. One of the best ways to keep them healthy and happy is by providing them a regular diet. Despite not needing a lot of attention, fish must be fed properly and regularly in order to live a long life. Sometimes it feels impossible to stick to a scheduled feeding. This is where automatic fish feeders come in handy. Aquarium fish feeders are devices that are designed to feed fish, turtles, or other aquatic pets at regular intervals. There are many benefits to having for your aquarium. For instance, there are times when you just can’t be at home when your aquatic friend needs food. It also ensures that your pets receive the right amount of food every time, so there is no over or underfeeding.

Cost And Value

Criteria Used for Evaluation
Value
Price isn’t too much of a concern with automatic fish feeders since all of the great ones are low priced. We used this criterion to get rid of overpriced options that didn’t offer equal value to their expense. Most of the products that we got rid of were for much larger tanks than what would be in normal homes. For consumer-grade level feeders, the price for top tier equipment won’t be that much more than decorations for a tank. This versatility in price is great for first-time buyers of automatic feeders.
Use
The next thing we looked at was the amount of food that could be included in the feeders, or for blocks the duration before they completely disappeared.
The results were surprising, with a lot of the better products lasting in excess of two weeks. We ranked the products that took multiple food types higher than the rest since they were much more valuable. This is reflected in the list by including a lot of the digital models that were favored for this specific feature.
By using a feeder that takes multiple types of food, you can use it with more complicated fish/tank setups.
Size
Size is something to take into consideration when buying an automatic fish feeder. Not only will it make a difference in smaller tanks, but more fish and larger fish will mean that more food needs to be added to the feeder.
The frequency of feeding will also come into play, so choosing smaller models over bigger ones won’t help out if you want longevity in the scheduling. By taking size into account as a criterion, we found that models offering the balance between their actual size and food capacity were overall better options.
Model
The design is something we took into consideration based on the number of users that want their feeder to match a theme. This was another criterion that only catered to electronic fish feeders, with a big advantage going to digital versions that had better casings.
There weren’t a lot of standouts with this criterion, so we gave a lot of points to brands that went beyond the usual static design. Most of the options looked similar to one another, so only a few really gained spots on the top ten for showing initiative with their theme. A good design also helps make fish more comfortable with having a foreign object in their space.
Durability
When consumers are leaving their tanks for days at a time, durability is important when the feeder is in a tank with larger fish. Durability was a criterion that also covered reliability and resistance when in a tank of aggressive fish.
Once your fish know where the food comes from they will swarm it, potentially causing damage if the feeder is weak. That is why high durability is important for an automatic feeder, at least an electronic one. Dissolvable options were treated favorably with this criteria since they didn’t suffer the same setbacks.
Expert Interviews & Opinions
Value Use Size Model Durability
It’s important for us to mention that fish feeders are made by different manufacturers as you can see from the list we have reviewed. They’ll all possibly have some differences here and there. This is the reason why we think that you should keep the manual that comes with the product.
Automatic fish feeders are different. They have different numbers of chambers where food can be loaded. Using a clock mechanism, the feeder rotates the chambers so that the food drops into the fish pond or aquarium at a specified time. This ensures that the fish are fed on a regular basis without the risk that they have too much food.
Other Factors to Consider
Features
Customization was the next criteria and was very specific to digital and analog automatic feeders. Since dissolving feeders don’t have any customization options, they were left off this criterion. This criterion covered scheduling options and how easy they were to set.
Digital automatic feeders won this round, with analog options still getting points here and there. Buyers should still consider getting extra batteries with their purchase in case included ones go out. For products that used proprietary batteries, we excluded them from the list since they were harder to buy in a pinch.
Battery Life
Battery usage is something we decided to add as a criterion due to the lack of information on the subject. Traditionally electronic feeders would last just fine for months without needing to change out the battery.
But the problem remains that a lot of electronic feeders still don’t include a low battery warning. So products with these criteria were given points for their battery indication options along with how long they went without needing to change out a set of batteries. The data helped out a lot of models that ended up in the top five of the list for their extraordinary battery usage capabilities.
Brand
There are no favored brands in the automatic fish feeding industry, although there is a lot of favoritism towards auto feeding tablets. The big type in that category are the ‘Pyramids’, large ones that dissolve and can last for up to 3-30 days. And beyond the tablets, there is a mix of traditional quartz timer feeders and new-age digital feeders.
Frequently Asked Questions
q: Will using tablets alter the water quality?
Only on tanks with bad filtration systems. You’ll notice the water get cloudy and nasty over time, so always make sure you have a good system in place before using them.
q: What Tank Types Accept Automatic Feeders?
All of them, thanks to universal brackets. If a bracket isn’t included, then purchasing one separately is still an option.
q: How long will one last?
The average for automatic fish feeders seems to be about two weeks. They vary based on size, brand, and price. There are plenty that can last beyond two weeks, but at that point, it may be better to get a live person to feed your fish.
Depending on the size and how aggressive the fish is, you may want to adjust the feeding time to less or more based on their eating habits. This is something that fish owners with multiple different types in one tank have to account for. With different personalities sharing a single feeder, one group may choose to eat more than the next.
q: What Are The Best Brands?
Eheim, Fish Mate, and Aquarium Pharmaceuticals are the leaders of the pack. But there are plenty of other companies not too far behind with their products. The differences between the feeding types offered by these three companies have given users a lot of options.
Electronic feeders are dominant, but not to the point where they automatically make the top three of every list. In fact, it isn’t uncommon to see brands cater to customers with multiple different types of fish feeders. Depending on the type of aquarium and fish breed needing to be fed, this can lead to a huge advantage in sales.
q: What Are The Best Types?
There are only two types of automatic fish feeders worth noting- electronic and dissolving. Electronic feeders operate by a battery and have a range of customization options. You can set feeding intervals and amounts at ease without having to dive too deep into the advanced options. This is the best product to use when you have different kinds of fish in one tank. The downside is that they are only as compatible as they tank they’re fitted to.
So if for some reason the feeder can’t fit on the tank, then you will have to default to using dissolving food. Dissolving food doesn’t require the use of a tank and works by slowly breaking down over time to feed your fish. With this method, only one type of food can be used since the food is the dissolving tab itself.
q: Is There A Limit To The Amount Of Fish It Feeds?
Yes, and there is also a limit to the size of the tank that is supported. This is something that is overlooked when getting an automatic fish feeder for the first time. Getting a model that doesn’t support the amount of fish you have in the tank leads to undereating. There are also concerns with the fish fighting over the limited amount of food available in the tank. To keep this from happening users should always check the tank size limit and compare it to the fish amount/size limit. Using these two variables will give you a better idea of whether an automatic fish feeder can support your use.
q: Why Are Some Fish Tanks Incompatible?
If an automatic fish feeder can’t activate its feeding mechanism in the tank, then your fish will starve. There are several reasons this may happen, starting with not being able to clamp the product within the tank. It needs to be immovable or there is a risk it’ll get bumped out of place and thrown off of the schedule. Fish sustenance type is something else that needs to be looked at since not all types are compatible. Certain pellets may be too big to put in the feeder without jamming it. So while the automatic feeder fits in the tank, it still isn’t guaranteed to support the type of food your fish eat.
q: Can You Set Feeding Intervals?
Yes, but only with electronic fish feeders. Your options will be limited by the specific model used, so not all intervals will be available. There are digital and analog options available, so choose wisely based on your level of understanding scheduling mechanics. The good news is that there are no major innovations between analog and digital fish feeders that would make you choose one over the other. Digital just happens to be easier to set up and use, but other than that analog and digital are largely the same. Other than setting intervals you can also set the amount of food that is released.
q: Are Feeding Blocks Bad?
Depending on who you ask, dissolving feeders will either be the best thing ever or the worst. They are often found under automatic fish feeding categories as ‘vacation blocks’ and are just as widely used as electronic feeders.
The only downsides are that you can’t manually set a feeding interval, there are less food type options and some tank fish/water types don’t play nice with dissolving food past a certain point. The upside is that there are no customization options so you can drop it and forget it, some blocks can even last up to two weeks and there is no danger of the block malfunctioning like an electronic feeder.
q: Are The Prices High?
Automatic fish feeding prices are generally low, costing no more than regular tank accessories. A lot of times they are even bundled with new tank purchases due to the low cost but high value. Consumers can purchase a quality fish feeder for the same price as fish tank decorations. And when you go away from electronic feeders and look into dissolving blocks, the price is even lower.
Either type of feeder is a must for any owner of fish, especially those that make frequent trips out of town. Higher tier options are available at expensive prices, but they don’t differ much from the low-cost models.
q: How Hard Are They To Set Up?
Electronic fish feeders can be set up in less than five minutes when following the included directions. This includes analog and digital choices, so the hardest part comes down to setting up the device in an optimal position within the tank. Taking a look at any quick start guide will give you a general idea of the process since most feeders are similar to set up. Dissolvable blocks are much different and require no setup- just drop and walk away. Special instructions that are included for the blocks concentrate on compatibility and cleanup.
q: Will Any Fish Nourishment Work With An Automatic Feeder?
No, so make sure to check the product's requirements. Some only accept flakes, while others accept pellets. There are even models that accept a mixture of the two and can dispense them separately. With no guarantee of food compatibility, it falls on the customer to make sure their model can handle the type of food the fish need. Putting the wrong food in a feeder will make it jam up, cause mold and can even pollute the water after a long period of inactivity. So buyers should put a priority on using the right food with the correct feeders.
