The Aquarium Co-Op Auto Feeder is perfect for everyday use whether you're at home or away from your fish tanks. Never over or underfeed your fish again as this unit reliably dispenses accurate portions of food every time it feeds. This feeder can be programmed to feed up to 4 times per day and runs on a rechargeable lithium-ion battery. Users may be able to get 3–6 months on a single charge, making it extremely easy to use and low maintenance.
Perfect for Daily Use, Breeding Fish, and Vacations
Make sure your fish are fed every day, whether you're at home or out of town. Useful for aquariums of any size to feed both nano and larger fish. Breeders like to use our auto feeders for feeding up to 4 small meals a day to keep their baby fish growing strong and healthy.
Easy to Use and Low Maintenance
Our auto feeder is very easy to program and allows you to automatically feed fish up to four times daily. Just follow the steps in the manual or video tutorial, and you're done. The 'Feed' button lets you manually feed your fish outside of pre-programmed times.
2 Options for Mounting
For both rimmed and rimless aquariums, the feeder has a screw-on mount that can fit up to 0.9 inches (24 mm) in thickness. For flat surfaces or acrylic tanks that don't have a rim, use the provided adhesive pad for mounting instead.
No AA Batteries Needed
Our auto feeder comes with a long-lasting, rechargeable battery that can run for 3-6 months, depending on daily use. The unit charges through a USB Micro B connection and takes about 3 hours to achieve a full charge. You can also leave the unit plugged in all the time so that it never runs out of power.
Adjust the Food Amount
The adjustable slider opening on the top of the feeder allows you to easily set the meal portion size. If you're only feeding a few fish and the smallest opening still drops too much food, one trick is to use a piece of tape to partially cover the slot.
After I watched the video and was able to set it up properly, the feeder worked great. I took off one star off because the instructions that come with it are difficult to understand. I strongly recommend the instruction video on the website which is excellent.

Great product; use superglue if using thicker rimmed tank
Love how easy to use it is and it is pretty water resistant by the way. However if you have a thicker rimmed tank like the Petco 75 gallon tank I highly recommend using super glue, the small lip on the rim makes this thing impossible to fit. After seven months of me having it on, it somehow fell into my tank while I was away and I came home to a dead community tank. I like this product way too much though because it gets my fish used to a spot on feeding time so I ended up super gluing it to the rim above the small lip. It is firm and won’t fall in now, & you simply pop it off from the rotating part when it comes to charging or refilling it with food. And surprisingly the water didn’t seem to affect it, it works perfectly fine till this date. On the bright side it got me away from my starter tank & gave me the opportunity to order a school of Celestial Pearl Danios! They should be coming in this week, super soaked to start a new community with the knowledge I have now thanks to the Co-Op Team!

Perfect for Holiday
The automatic feeder is easy to set up. Instructions were very clear. I was away for two weeks and came back to my happy healthy community tank.

Great Auto Feeder
I’ve been using this for several weeks. I recently was gone for five days on vacation and came back to fish that were fat and happy. This feeder has kept perfect time since I got it. I removed one star because the smallest opening is still quite large if you are feeder only a few fish and/or small food. In my case, I am feeding about a dozen guppies the magic nano feed. I had to use tape to make the opening very small. Being able to have finer adjustments on the opening size would be nice, but overall this is a great feeder!

Great feeder
Basic setup is very simple, tested it a few days while I was at home so I knew it would feed while I was away. Worked as advertised

A Well Designed Tool
I've been researching autofeeders and I went with a trusted source. I am pleased with what I got. The feeders are relatively easy to adjust, flexible enough to adapt to my aquariums (which happen to all have lids) and do a decent job. That being said, it is still tough to get just the right setup, but that is going to be the case with any auto-feeder solution. Lots of trial and error are required.

This has been a great addition to my tank. I love the fact that I can feed a smaller volume of food multiple times a day with ease.

Best auto feeder I’ve had
Works great and better than most others I’ve had. My only issue is that it’s not USB-C charging. If they updated this charging port I would definitely buy another!
