There are plenty of reasons to accept a little help with feeding your fish. Maybe you’re going on vacation, you’re prone to forgetting to feed them, or you struggle with feeding them the correct amount. No matter the circumstances, an automatic fish feeder can help.

TOPBRY Automatic Rechargeable Fish Feeder

This automatic fish feeder is great because it is customizable to fit most setups. It hooks onto the top edge of the tank and can be turned 360 degrees, so you can put it on the side of the tank that works best for you and your fish.

The automatic fish feeder takes care of the rest.

Another helpful feature this feeder has is its power source. It is charged with a USB cable, so you don’t need to worry about having batteries on hand. This feeder only needs to be charged once every 3-6 months, so the battery is low maintenance as well.

Frequently Asked Questions:

Q: My aquarium has a cover on at all times. Can I still use an automatic fish feeder?

A: Absolutely! Simply attach the feeder near one of your tank cover openings to allow the food to enter your tank. Most automatic fish feeders are adjustable, so you can set them to the correct angle to make just about any setup work.

Q: Can I use an automatic fish feeder to feed my fish while I am on vacation?

A: This is a perfectly acceptable use, and is actually one of the most common reasons people purchase automatic fish feeders. You will want to make sure the feeder has new batteries and is filled with enough food to cover the entire time you will be gone. If you are going on an extended trip, you may want to have a friend or family member stop by your house a few times to ensure the feeder is still full (and still has enough battery to feed your fish).

No matter what you need an automatic fish feeder for, you can find your new device from the list of products reviewed above. Consider the types of fish you have in your tank, the kind of food they eat, and how many times a day they need to be fed. Decide if you prefer a rechargeable option or one with batteries.
