The Fish Mate F14 is the automatic fish feeder we would buy for a vacation. Instead of a drum that dispenses an adjustable amount, it has 14 separate portion compartments, so it cannot jam open and empty its whole load into the tank. It delivers 1 to 4 timed meals a day, takes flakes, pellets and sticks, runs over a year on one AA battery, and carries a 3-year guarantee, according to its listing.
Overfeeding, not starving, is the bigger risk when you are away. University of Florida extension scientists call overfeeding a major cause of high ammonia, so a feeder that gives too much can do more harm than a missed meal. The picks below cover vacations and everyday automated feeding.

Best for vacations
Fish Mate F14 Fish Feeder
Fourteen separate portions, so a fault cannot dump all the food at once.
- Capacity
- Up to 14 individual portions
- Meals per day
- 1 to 4
- Food
- Flakes, pellets, sticks
- Power
- 1 AA battery, over a year (per the listing)
Pros
- Separate compartments limit any overfeeding to one portion
- Each meal trickles out over about 2 hours, per Pet Mate's instructions
- Sits on a hood or clamps to a glass edge; 3-year guarantee once registered
Cons
- 14 portions limits long trips at multiple meals a day
- You fill each compartment by hand
The F14 is a wheel of 14 compartments. Its listing says it delivers 1 to 4 timed meals a day, handles flakes, pellets and sticks, and measures 5.47 by 4.65 by 1.54 inches. Pet Mate's printed instructions add the details: each meal is dispensed gradually over about 2 hours, four mealtime pegs come in the box, and an alkaline AA battery should last 12 months in continuous use. The 3-year guarantee applies once you register the purchase on Pet Mate's website within 14 days.
At one meal a day, 14 portions covers two weeks. Fill each compartment with a single small meal, and run it for a few days before you leave to check the portion size.
Mounting is where the listing and the instructions differ. The listing says the F14 attaches to a hood, condensation tray or glass edge. Pet Mate's instructions put it on the hood with its spout over the feeding hole (cut a 1.25 inch, 30 mm hole if there is none) and say the condensation tray is not normally recommended, because moisture there clogs the food, unless an air pump is connected to the feeder's AIR port. On a tank with no hood it sits on the two supplied clamps. Pet Mate also asks for a 14 day trial in place before you leave it unsupervised.
Best for everyday use
EHEIM Everyday Fish Feeder
A programmable drum feeder from EHEIM with a fan that keeps food dry, and a 3-year warranty.
- Capacity
- Drum
- Meals per day
- Up to 4, once or twice each (EHEIM manual)
- Food
- Flakes, granules, small pellets
- Power
- 2 AA alkaline batteries (EHEIM manual)
Pros
- Integrated fan and ventilation keep food dry (per the listing)
- Set it and leave it for daily feeding
- 3-year warranty with proof of purchase
Cons
- Stock is scarce
- Drum feeders can clump in humid hoods; check weekly
EHEIM's Everyday feeder is a programmable drum unit meant to feed every day, with you at home or away. Its listing highlights an integrated fan and ventilation system that keeps the food dry, the main failure point of drum feeders over a humid tank, and gives a 3-year warranty with proof of purchase.
EHEIM's manual for its 3581 feeder, the model behind the Everyday (the listing gives part number 3581090), fills in what the listing leaves out. It runs on two AA alkaline batteries, and EHEIM says not to use rechargeables. It stores up to four feeding times, and each can turn the drum once or twice, a minute apart; a slider on the drum sets how much falls out. An LO symbol warns of low batteries, and about three days later the unit switches itself off so the drum does not stop facing down. Change the batteries within a minute to keep the program.
EHEIM limits it to dry food such as flakes and granules, never live or frozen food, and says the drive unit's rear air intake must stay out of the humid air above an open tank and must not be covered. On a tank without a cover, it hangs on the rim with the supplied holder.
Best large capacity
fishkeeper USB Automatic Feeder with LCD (520 mL)
A 520 mL rechargeable feeder with an LCD for scheduling and three portion sizes, for pellet-fed tanks.
- Capacity
- 520 mL
- Meals per day
- Programmable; daily to every 4 days
- Food

Pros
- LCD shows feeding times, portions and battery
- Sliding drawer and flap help keep food dry
- Three discharger sizes; 2-year warranty (per the listing)
Cons
- The listing says it is not suitable for flake food or large fish
- Large capacity tempts overfeeding; set small portions
fishkeeper's feeder holds 520 mL of food, programs feedings from daily to every four days with set times and portions on an LCD, and runs 2 to 4 months on a 700 mAh rechargeable battery, according to its listing. It has a sliding drawer and flap to keep moisture out and three discharger sizes. The listing is clear that it does not suit flakes.
Best budget
FISHNOSH Automatic Fish Feeder
A simple timer feeder with up to three feeding times a day, each with up to three rotations.
- Capacity

Pros
- Refill without removing it from the tank

- Seller's figures
FISHNOSH's feeder can be set for up to three feeding times a day, each with up to three rotations of the cup, according to its listing, and refills without being removed. It suits a weekend away on a small tank. Run it at a single rotation, once a day, to start.
Do you need an automatic feeder?
For a weekend, many keepers simply feed before leaving and after returning. University of Florida extension scientists note that uneaten food decomposes into ammonia and that overfeeding is a major cause of high ammonia. A feeder earns its place for trips of several days or longer, for fry and small fish that need frequent meals, and for keepers who want consistent daily feeding.
The four feeders side by side
The four feeders differ most in how they hold food and what powers them. Figures for Fish Mate and EHEIM come from the makers' instructions unless marked; the other two are from their listings.
| Feeder | Holds | Feedings a day | Power | Food | Guarantee |
|---|---|---|---|---|---|
| Fish Mate F14 | 14 separate portions | 1 to 4 | 1 AA alkaline, 12 months | Flakes, pellets, sticks (per the listing) | 3 years, registered within 14 days |
| EHEIM Everyday | Drum with a dosing slider | Up to 4, each once or twice | 2 AA alkaline, no rechargeables | Dry flakes and granules | 3 years with proof of purchase (per the listing) |
| fishkeeper USB | 520 mL | Set times, daily to every 4 days | 700 mAh rechargeable, 2 to 4 months | Pellets and granules, not flakes | 2 years |
| FISHNOSH | Drum | Up to 3, up to 3 rotations each | See listing | Most fish foods | 2 years |
How long each feeder covers a trip
Trip length for the Fish Mate F14 is simple arithmetic, because each meal empties one of its 14 compartments: 14 days at one meal a day, 7 days at two, and 3.5 days at four. For a trip longer than two weeks, the F14 alone cannot cover daily meals, so ask someone to refill the wheel or to feed pre-measured portions.
Trip length for a drum feeder depends on the portion you set, so measure it. Fill the drum, run the feeder at your chosen setting for a week at home, and note how far the food level drops; that tells you how many days a full drum lasts. Drum food also sits in humid air the whole time, which is why EHEIM's drive unit has an air intake and Pet Mate's instructions give a whole section to clogging.
How much the feeder should give
Portion size for an automatic feeder should match what you would feed by hand. Veterinarian Melissa Witherell, writing for PetMD, advises feeding once or twice a day depending on the species, only as much as the fish eat in two to five minutes, and removing uneaten food right away. Tetra's setup guide gives a similar rule: one to three small feedings a day, only what the fish eat in about five minutes.
A feeder cannot net out leftovers, so set it at the low end of those rules. Watch a few feedings while you are home: if food is still drifting or lying on the gravel several minutes later, cut the portion.
How we chose
- Portion control. Separate compartments (Fish Mate) cap the damage from a fault.
- Keeping food dry. Humidity clumps food in drums; fans and sealed drawers help.
- Food types. Some feeders handle flakes; some do not.
- Power and warranty. Battery life and the maker's guarantee.
Setting up for a trip
- Install the feeder two weeks ahead and run it while you are home; Pet Mate asks for a 14 day trial of the F14 in place before unsupervised use.
- Set the smallest portion that your fish finish in a couple of minutes.
- Do a water change and a gravel vacuum the day before you leave.
- Test ammonia and nitrite with a test kit so you leave with a healthy baseline.
- Put lights on a timer and check that the heater and filter are working. A battery air pump covers a power cut.
When a feeder clogs or stops
- Clumped food. Pet Mate's fixes for the F14: switch to pellets, move the airstone away from the feeding hole or turn the air down, raise the feeder 1 to 2 inches (25 to 50 mm) above the hole and leave its lid open, or connect an air pump to its AIR port so moist air cannot get in.
- Stale crumbs. Pet Mate recommends lifting out the F14's rotor after 14 days of continuous use and brushing away the food fragments underneath.
- Dead batteries. EHEIM's LO symbol gives about three days of warning before the unit shuts off, so fit fresh alkaline cells before any trip. Pet Mate says to take the F14's battery out when you stop using it.
- The wrong food. EHEIM's feeder takes only dry food, and the fishkeeper listing rules out flakes.
What to skip
- Vacation "feeder blocks" that dissolve in the tank. They can foul small tanks.
- Asking a neighbor to feed without pre-measured portions. Well-meant overfeeding is common; leave daily pill-box portions.
- Large portions "just in case".

Frequently asked questions
Are automatic fish feeders reliable?
Good ones are, but drum feeders can clump in humid air or jam. A compartment feeder like the Fish Mate F14 limits any fault to one portion. Run any feeder for a week or two before you rely on it; Pet Mate asks for 14 days with the F14.
Should I use an automatic feeder for a weekend away?
Often it is not needed for a short trip, and an overfeeding feeder is a real risk: University of Florida extension scientists identify overfeeding as a major cause of high ammonia. For longer trips, a compartment feeder caps any fault at a single portion.
Can automatic feeders dispense flakes?
Some can. The Fish Mate F14 handles flakes, pellets and sticks, according to its listing. The fishkeeper USB feeder's listing says it is not suitable for flakes.
How do I stop an automatic feeder from overfeeding?
Set the smallest portion your fish finish in a couple of minutes, test it for a week while you are home, and use a compartment feeder for longer trips.
Where should an automatic feeder go on the tank?
Over open water away from the filter intake, mounted on the hood, tray or glass edge as the maker describes, where splashing will not wet the food.
