Fish Tank Auto Feeders

Auto feeders are essential for maintaining a balanced aquatic environment for fish. These devices automate feedings and dispense adjustable amounts of fish food at preset intervals, ensuring your aquatic companions are fed and content. With fish tank auto feeders, you can relax knowing your aquatic friends are well-fed and content, even when you’re away, allowing you to focus on other activities. But with so many models and options on the market, how do you select the best auto feeder for your needs?

Fish Tank Auto Feeders

Why Use an Automatic Fish Feeder?

So why exactly should you consider using an automatic fish feeder? What benefits do they offer compared to manual feeding? There are several excellent reasons to give fish tank auto feeders a try:

  • Feeding Consistency – Fish thrive on stable routines. Auto feeders can deliver meals at precise, consistent times. This prevents over or underfeeding, which stresses fish.
  • Convenience – You no longer have to drop everything 2+ times a day to feed your fish. Auto feeders take care of it for you! This frees up your schedule.
  • Peace of Mind During Travel – Auto feeders let you relax when away, knowing your fish are automatically fed. No more relying on neighbors or rushing home.
  • Portion Control – These devices allow exact amounts to be dispensed, preventing overfeeding and food waste. No more guessing portions.
  • Automatically Observe Feeding – Using an auto feeder can give you a sense of your fish’s appetite and health. Uneaten food indicates issues.
  • Flexibility – Many auto feeders are programmable, letting you fine tune feeding times and amounts as needed.

Auto feeders are a game changer for fish-keeping hobbyists with busy lifestyles. Let’s now explore the types available and key features to compare.

Types of Automatic Fish Feeders

There are a few main types of automatic fish feeders to be aware of:

Automatic Betta Fish Feeder

As the name suggests, these auto feeders are tailored for betta fish. Bettas have especially small mouths and cannot handle large amounts of food. They eat tiny portions multiple times a day. Automatic betta feeders dispense small 3-5 pellet portions 3-5 times daily. This prevents waste while giving bettas the frequent small meals they require.

Popular options like the Everyday Feeder or Betta Buddy release just a few pellets with each use. These feeders are compact, with small hoppers to match betta appetite. Their simple design includes an adjustable feed rate, programmable 1-4 feedings daily, and battery powered operation.

Automatic Fish Feeder for Flakes

Flake food, made up of crushed and dried aquatic materials, is a common staple diet for many freshwater fish. Automatic fish feeders designed for flakes feature wider openings and mechanisms to handle flakes’ lightweight texture.

These auto feeders allow owners to feed fish flakes multiple times a day conveniently. Their motors vibrate to shake flakes down into the tank. Dispensing flakes prevents them from getting soaked and spoiled in the tank water.

Eheim and Pentair automatic flake feeders include moist/dry sliders to adjust flow for optimal flake dispensing. These feeders have large hoppers to hold several weeks’ worth of flakes.

Automatic Fish Feeder for Goldfish

Goldfish have higher food intake needs than most aquarium fish. They also appreciate frequent smaller meals throughout the day. Automatic feeders created for goldfish allow owners to feed appropriate goldfish diet portions consistently.

These feeders provide the frequent, smaller goldfish feedings required to prevent bloating. They also allow feeding veggie-based goldfish foods like spirulina flakes which easily spoil in water.

Goldfish auto feeder models contain large hoppers and can dispense small amounts as needed. Brands like Fish Mate and PondX excel at goldfish tank feeders.

Features to Consider

Now that you know the main styles of automatic fish feeders, let’s explore the key variables and features to compare when shopping:

Ease of Use and Programming

Look for an intuitive auto feeder that’s simple to program. It should have clear instructions and be adjustable if your schedule changes. Easy disassembly for cleaning is also useful.

Power Source

Auto feeders are powered via batteries or electricity. Battery operated models offer more placement flexibility. Electric feeders have a continuous power source. Choose what fits your setup.

Capacity and Storage

The size of the feeder’s hopper determines how much food it can hold. Larger hoppers require less refilling. Just ensure it’s easy to check food levels.


The auto feeder should accurately dispense portions and consistently operate as programmed. Reliable mechanisms prevent malfunctions.

Feeder Type

Feeders can be free-standing, mounted on the tank rim, or fully submerged. Choose what suits your setup.

Tank Compatibility

Auto feeders must suit your tank’s water conditions (freshwater, saltwater etc) and size. Submersible models also require adequate clearance.

Speed and Noise

Look for quick, quiet food delivery. Motored feeders should run silently to avoid disturbing fish.


The feeder should have safety features like lid locks, ventilation, and waterproofing. Fully enclosed units keep moisture out.

Top Picks

Let’s look at top recommended auto feeders in three popular categories:

Best Auto Feeder for Fish Tank – Eheim Everyday Fish Feeder

The Eheim auto feeder is a consistent top seller for its reliable performance, versatility, and easy programming. It operates via battery, allowing placement anywhere on the tank.

With twin compartments for different foods and quantities from 1-12 daily feedings, it’s highly customizable for any setup. Its quiet motor and small footprint make it a great choice.

Best Auto Fish Feeder for Reef Tank – Coralife Auto Feeder

This digital auto feeder is engineered for saltwater reef tanks. It can handle moist foods like brine shrimp and mysis shrimp without clogging.

The Coralife feeder allows up to 12 daily feedings 0.5-20 seconds in length. It runs on AC power with a backup battery when electricity fails.

Best Automatic Fish Feeder for Small Tank – Huijukon Fish Feeder

Perfect for mini tanks under 5 gallons, this compact feeder has a narrow design and small 10g hopper. It securely mounts on nano tank rims.

Despite its size, it packs great features like moisture resistance, clog-free operation, and battery powered operation with up to 4 daily feedings.

Special Cases

Some tanks call for auto feeders with specific design tweaks:

Automatic Fish Feeder for Tank with Lid

Aquariums with glass covers or hoods have limited vertical space for auto feeders. Special “low profile” feeders are designed to work in these setups.

Two main options provide feeding automation for covered tanks:

Rim-Mounted Low Clearance Feeders

These attach directly to the tank rim while fitting under hoods and lids. They hug the rim tightly to save space.

Look for short, compact feeders less than 3 inches tall. They should have universal mounting clamps for rim compatibility.

Features like moisture resistance and pinch guards allow safe use under tank tops. Popular rim-mounted options include the Hygger Low Profile Auto Fish Feeder and the Eheim Battery Operated Feeder.

Hanging Lid Feeders

These feeders are suspended from a tank hood or lid opening to feed fish. Vacation fish feeder blocks work this way, dangling into the tank while slowly dissolving.

More advanced hanging feeders like the Pentair and Eheim models feature programmable timers and food hoppers. A control panel is mounted on the outside for easy programming. The food delivery chute dangles into the interior.

Feeder Fish Tank Setup

If housing feeder fish like guppies to provide live food for predatory species, a feeder tank auto feeder ensures your feeders stay well-fed. These feeders provide small frequent meals to keep feeder fish producing nutritious live young.

Pros and Cons

Advantages of Auto Fish Feeders

  • Convenience – Handling daily feeding is automated so your schedule is free
  • Consistent feeding times – Fish benefit from meals at precise intervals
  • Exact portions – No more over or underfeeding when amounts are preset
  • Safety during travel – You can relax knowing your fish are fed
  • Observation of intake – Uneaten food makes appetite issues obvious
  • Flexibility – Many feeders are adjustable and programmable

Disadvantages and Limitations

  • Can’t completely replace observation – You still need to watch your fish at times
  • Potential malfunctions – Mechanical faults can lead to overfeeding
  • Requires electricity/batteries – Manual options are self-sufficient
  • Live food not possible – Auto feeders can’t provide live brine shrimp etc
  • Can be expensive – Quality programmable feeders often cost over $50
  • Clogging risk – Some foods may jam the release mechanism

While very helpful, auto feeders aren’t foolproof. Use them alongside occasional manual feeding and tank monitoring. Perform regular feeder maintenance and cleaning as well.

Additional Considerations

Fish Pond Auto Feeder & Fish Pond Automatic Feeder

Outdoor ponds require uniquely designed auto feeders. They must be weather/water resistant and able to hold large amounts of food to nourish schools of pond fish.

These heavy-duty feeders contain weather-tight compartments for pond fish food. Programmable models allow custom feeding schedules.

Marine Tank Auto Fish Feeder

Saltwater species have unique dietary requirements, including live foods. Marine auto feeders are designed to handle brine shrimp, mysis shrimp, plankton, and other moist seafood without clogging.

Water-resistant marine feeder motors run silently to avoid disturbing sensitive reef fish. They connect to power outlets for continuous operation.

Nano Fish Tank Automatic Feeder

Mini desktop tanks under 5 gallons need a perfectly sized small auto feeder. Compact feeders fit in tight spaces and hold just enough food for nano fish.

Look for feeders no wider than 2 inches with suction cups for rim mounting. They should have moisture guards and small, adjustable feed amounts.

Small Fish Tank Auto Feeder

Larger than nano but smaller than big display aquariums, 10-20 gallon starter tanks need right-sized feeders. Look for feeders with narrow or modular bodies to allow adjusting capacity.

Small tank feeders should mount securely on rims and have easy-access hoppers to replace food. Programmable models provide feeding flexibility.

Tropical Fish Tank Automatic Feeders

Tropical community aquariums typically contain schools of small colorful fish like tetras, rasboras, and danios. They appreciate several small meals per day.

Tropical tank auto feeders portion out tiny amounts of food like flakes, mini pellets, and freeze dried treats. This prevents waste while satisfying tropical fish feeding needs.

Vacation Feeding

Leaving your fish for days? Auto feeders keep your fish fed in your absence. Here are some tips:

How to Feed Fish While Away

Set your auto feeder to dispense daily meals as usual. Check food levels, and fill the hopper to overflow before leaving. Rinse and prime the feeder to prevent clogging.

Have a friend come by midway for longer vacations to refill the feeder and check functioning. Perform a water change before leaving.

Vacation Fish Feeder

These specialized feeders are single-use but provide 2 week’s worth of preset feedings. Drop one in the tank, and food blocks slowly dissolve to nourish fish while you’re gone.

They’re convenient “set and forget” options for shorter vacations. However, they don’t allow custom programming or monitoring.


Do Fish Tanks Come with Auto Feeders?

Most standard fish tanks don’t include auto feeders with purchase. However some high-end kits may include built-in automatic feeders, especially for saltwater setups. These can’t be removed for use on other tanks.

How Often Should You Feed Fish Automatically?

Follow the normal feeding frequency for your particular fish. Most community tanks do well with 2-3 automatic feedings daily. Bettas and other small species need more like 3-5 meals. Goldfish prefer 4-6 smaller daily feedings.

Can You Overfeed with an Auto Fish Feeder?

It’s possible if you program excessive feeding times/portion sizes. Start conservatively and adjust upwards based on consumption. Watch for uneaten food, which signals overfeeding. Do weekly feeder cleanings to prevent malfunctions.
