The 10 Best Auto Fish Feeders
We spent 45 hours on research, videography, and editing, to review the top choices for this wiki. Can’t remember to feed the fish every day? Going on vacation? You’ve got three choices: ask one of your flaky neighbors to help; wait and hope for a robot butler to be invented; or get one of these nifty auto fish feeders. They can be programmed to accommodate different types of feeding schedules and portion sizes — but just be sure to test them for a few days before you leave for a week. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best auto fish feeder on Amazon.
Fish Need Food, Too
The feeder itself attaches to your tank or lives at the lip of your pond for easy feeding.
If it were true, and fish really had a memory of about 30 seconds, how would they ever remember to eat?
They say that fish have short memories. More recent studies disprove that myth, but it's a good myth, so it persists. If it were true, and fish really had a memory of about 30 seconds, how would they ever remember to eat? One moment they'd realize they were hungry, and the next moment they'd forget. Then, they'd remember again and forget again. They'd probably starve.
It's a good thing, then, that they aren't in charge of their own food, at least not when they're in your pond or aquarium. They face another problem there, however, and this one is not a myth: People are forgetful.
I can recall the names of musicians in obscure indie bands from the 90s, I can remember the years most films came out, and I can usually remember to dress myself in the morning. The oil in my car? I never remember to change it. That rent check? It's coming late. I've got the money, I just apparently don't know how to read a calendar.
Until you're in the thick of it, you can't know what you can and cannot trust yourself to remember. That's why having a system that will automatically feed your fish is so crucial, especially to new tank owners or to folks who like to jet-set around the globe and can't be home to distribute the flakes.
These automatic feeders come in a variety of styles, but they all operate on the same basic principle. There's a timer in each that you program to release a predetermined amount of food at a given hour or hours in the day. The feeder itself attaches to your tank or lives at the lip of your pond for easy feeding.
At the strike of that hour, your feeder either releases food from a single-serving-sized chamber or it opens a release door just long enough for gravity to take a certain amount of flakes down to the water.
Finding Your Feeding Schedule
Knowing exactly why you need an automatic fish feeder will lead you quickly to a small number of options off our list, and the parameters of your tank or pond should get you even closer to a choice.
There are some models on our list that let you go even longer between refills and that have adjustable quantity releases to suit your specific swimmers.
Personally, I work pretty long days. Sometimes I'm out of the house 16-18 hours. If I owned a dog, it would likely destroy the bulk of my apartment out of spite. If I owned a cat, it would get carried away by a coyote. So, I turn to fish, and an automatic feeder keeps me from having to buy new fishy friends every few weeks.
Technically, I don't need a fish feeder that can store more than a couple of day's worth of food, but I also don't want to refill the thing every night, so I reach for a model with a slightly larger hopper, that way I can go a long weekend without worrying that my fish have been roped into a hunger strike against their will.
There are some models on our list that let you go even longer between refills and that have adjustable quantity releases to suit your specific swimmers. If you're the type to take longer trips for business or pleasure, you want a feeder that's got a large hopper and a very controllable release schedule.
There are more enormous models to choose from, with hoppers measuring in pounds instead of ounces, and these are outfitted less for your aquarium and more for an outdoor pond (which I hope is a redundant term, and that you don't have a pond your living room).
A Fish Under Your Bed
We have the Romans to thank for bringing fish indoors. Leaders of that great empire kept sea barbels in marble tanks under their beds and the beds of their wealthy visitors. Why exactly they kept them under the bed is a bit of a mystery, but we'll assume it was as close as they could come to snuggling up to something warmer, fluffier, and air-breathing.
By 1860, the Germans, British, and French all had large aquariums in their public zoos, housing both fresh and saltwater creatures.
The Roman aristocrats had the first automatic fish feeders, as well: slaves! They couldn't be programmed as easily, and their upkeep was plenty more complicated, but they were also multi-taskers, so feeding Roman fish only accounted for a portion of their duties.
The first aquariums of note appeared in the early 19th century, when Jeanne Villepreux-Power created a sealed terrarium that eventually also held water and fish. By 1860, the Germans, British, and French all had large aquariums in their public zoos, housing both fresh and saltwater creatures.
One hundred years later, superior sealants of tar and silicone allowed consumers in the US their first opportunity to own saltwater fish at home without the fear of corrosion and the eventual collapse of the system.
One of the earliest patents for an automatic, electric fish feeder dates the device back to 1953, when Seymour Smolin proposed a fish feeder with timed cycles, a hopper for storage, and a device for attaching the feeder to the side of a home aquarium. Sounds pretty familiar, doesn't it?
