Best Automatic Fish Feeder

|

Our aquarium fish depend on us to provide a healthy aquarium to live in. Stability and consistency are important characteristics of good aquarium care. Freshwater and marine fish require a good diet to grow, develop beautiful coloration and maintain good health. Most aquarists use high-quality prepared foods like flakes, crumbles and pellets as the main way to feed their fish.

Fish food manufacturers work hard to provide balanced, vitamin and mineral-rich diets. Proteins, fat and fiber are scientifically calculated and blended into the fish food recipe. Ingredients are carefully processed to protect the vitamin content in the final food products. Aquarists are fortunate that there are so many types of fish food products to choose from.

Dangers of over-feeding aquarium fish

Tropical, marine and goldfish like to forage for food throughout the day. In most cases, aquarium fish can be fed one or more times a day. If you feed several times a day, smaller, easily consumed portions are recommended. Excess food will simply decay in the aquarium, causing a surge in harmful ammonia and nitrite. The phosphorous in the food can also stimulate algae growth.

Gray, cloudy water, caused by bacterial blooms, are often caused by over-feeding the aquarium. The decomposing food is an energy source for naturally-occurring bacteria in the tank. Normally they are invisible and part of the aquarium’s ecosystem.

Over-feeding with fish foods stimulate the bacteria to feed and reproduce. The bacteria will continue to reproduce so much, a bacteria cloud forms in the water. All of these water quality problems will stress the fish, which can lead to a compromised immune system. Stressed fish become more susceptible to fish diseases that cause cloudy eyes, ragged fins, ulcers and gill damage.

Holidays, vacations and your aquarium

Many aquarists get stressed out when they have to leave their aquarium unattended. Going away on a fun vacation should be a relaxing event. You want to unwind and forget about life’s cares. But what about your aquarium? Who can you trust to feed the fish properly?

Most aquarists ask a neighbor or family member to feed the fish while they are away. Some people are very nervous about over-feeding. They worry that something they’ll do will cause the fish will die. Many “volunteer fishkeepers” confess that they only feed the fish once out of fear. On the other end of the spectrum, there are “helpers” who add too much food, believing the fish will starve without a huge scoop of food every day. What’s the answer to all of these fish-feeding concerns? The automatic fish feeder!

Automatic fish feeders to the rescue!

Automatic fish feeder is mechanical device that periodically add fish food to the aquarium. The devices have been popular in the hobby for over 30 years. Designs get updated every few years as improvements are developed.

Commercial automatic fish feeders are used at fish hatcheries, grow-out ponds and at feeding stations in outdoor lakes and ponds. These rugged devices are too large and expensive for aquarium use. They’re built for outdoor use and hold a very large amount of food pellets. The good news is engineers have developed aquarium-sized fish feeders that are designed to dispense small amounts of tropical fish foods. These devices are perfect for feeding your fish while you’re away on vacation, holidays, business trips or anytime you’re not at home.

How automatic fish feeders work

There are several designs but all automatic fish feeders have several features in common. Fish food is held in some kind of drum or chamber. A programmable timer controls when the food is added to the aquarium. Some automatic fish feeders offer more features, like the ability to feed multiple times a day.

Automatic fish feeders have become more refined over the years. The one problem that sometimes affects automatic feeders is moisture. The feeder is typically placed on top of the aquarium, just above the water surface. The food drops into the aquarium, from the food container. Moisture from the aquarium can collect on the feeder, especially where the food comes out. This is highly dependent on the feeder design.

Some feeders have a dedicated slot where the food must pass. This is where moisture can cause flake food to “gum up” and clog the slot. Other feeder designs use a rotating chamber that faces away from the water surface. The chamber rotates down toward the water only at feeding time. This reduces the chances that moisture can collect where the fish food comes out.

Most automatic fish feeders are battery powered. This makes it easy to place the feeder anywhere on the aquarium. It also ensures the feeder works even if there is a power outage.
