Automatic Fish Feeder Buyer’s Guide

Why would a consumer want an automatic fish feeder?

The need to feed a pet is an essential part of being a good pet owner. Every now and then, it’s good to take a vacation. Most people in want of an automatic fish feeder purchase one to avoid paying another person to come into their homes and feed the fish. Some people purchase the product to avoid the stress of constantly having to remember to feed their fish. Regardless, the automatic fish feeders serve a purpose of easing the troubled mind of a pet owner that may not be able to feed his or her fish in a timely manner.

What should a potential buyer look for in an automatic fish feeder?

There are a variety of features for each automatic fish feeder. Which features are the most important are the consumer’s choice? For example, a potential buyer might prioritize looking for a feeder that can feed the fish over a longer time period as opposed to one that has an LCD screen.

What are some key features to look for in an automatic fish feeder?

There are many features to be on the lookout for. Some questions to ask while looking at each fish feeder are:

  • Does it have an easy-to-read LCD screen? The LCD screen is useful when trying to operate the machine in both the setup and the continued use of the said machine.
  • How large is the capacity of the feeding drum? The capacity of the feeding drum will ultimately determine how frequently the user would have to refill the feeder. The larger the drum, the less frequently the chamber would have to be refilled.
  • How frequently can the feeder feed the fish? This is an important question to consider, as it may affect the livelihood of the fish. If the fish are used to being fed multiple times per day, then an automatic feeder that only feeds the fish once per day will not be useful.
  • What batteries are required to power the feeder? This would affect the type of battery the consumer would have to purchase in the long run. If a feeder requires AAA batteries instead of AA, the consumer might have to go out of his or her way to purchase the batteries.
  • Are batteries included? Mostly this will impact whether or not the potential buyer will have to invest in batteries in addition to the automatic fish feeder.
  • How long will the batteries last in the feeder? This question is as important as the capacity of the drum size because it requires more or less attention depending on the answer. If a single AA battery only lasts a few weeks with one feeder and two AA batteries last over a year with a separate feeder, it may be more of a money-saver to go with the feeder that doesn’t require frequent battery changes.
  • Is there a manual feed option? A manual feed option is useful for when the pet owner wants to feed the fish on his or her own. It’s a neat feature to have on an automatic fish feeder.
  • Is there an easy way to turn off the feeder if need be? Some feeders will require the user to pull the batteries out in order to turn off the machine.
  • Will this feeder fit on the side of the aquarium? Most automatic feeders will have a way to adjust for the size of the aquarium but each feeder is different.
  • Does this feeder have a way to prevent the food from going stale or turning into mush? Some ventilation systems or moisture resistant coatings are used to keep the fish fed with food in the same state that it was when it was placed in the machine. Some machines will jam or not dispense food if the feeder becomes too moist.

What are some drawbacks to purchasing an automatic fish feeder?

Truthfully, there aren’t many drawbacks to investing in a fish feeder. The biggest drawback is perhaps the most deadly. If a consumer purchases a fish feeder without comparing the various feeder or considering the needs of the fish, the feeder may not work properly or become mush, potentially leading to the death of a fish. A second drawback would be if the automatic fish feeder is not ideal for the size of the aquarium or will not hold the proper type of fish food and ends up becoming a waste of money. It’s important to be a good consumer and make an effort to find the best product that will meet the needs of both the buyer and the fish.

In general, what is a good price to pay for an automatic fish feeder?

Each automatic fish feeder has different features at different price points. A fancy feeder with a large variety of features to utilize will typically cost more than a simple feeder with the bare basics. Overall, an automatic feeder will cost no more than thirty dollars and no less than ten.

Do automatic fish feeders come with some type of insurance?

In some cases, automatic fish feeders will come with some type of warranty or money-back guarantee. However, fish feeders aren’t perfect and can break for any number of reasons. For this reason, some companies or producers of the fish feeders will not offer these types of insurances. When looking to purchase an automatic fish feeder, be sure to check if the company or seller offers either a warranty, a money-back guarantee, or both.

How long do automatic fish feeders last?

If the feeder was carefully chosen, automatic fish feeders can last up to fifteen years.

How often does a potential buyer have to clean the fish feeder?

Generally, a fish feeder should be clean and have no buildup of algae or scum. When a user begins to see signs of heavy buildup, that is the most ideal time to clean the feeder.

How does one safely clean a fish feeder?

A simple warm towel or fish-friendly cleaning cloth is acceptable to use. Avoid using any soaps that would be potentially dangerous to the fish. Simply wipe away any excess buildup.

What makes these the best automatic fish feeders?

These ten feeders are considered the best automatic fish feeders on the market due to their features, price, and user satisfaction. Each one is rated highly by consumers that purchased the product and would recommend it to someone else.
