Automatic fish feeders are essential for aquarium owners who travel frequently or maintain busy schedules. These devices ensure your fish and aquatic pets are fed consistently, helping prevent overfeeding, reduce water quality issues, and maintain a healthy tank environment.
The good news for reptile lovers is that many automatic fish feeders are also excellent for feeding aquatic turtles. They are particularly well-suited for dispensing dry pellets and granules, which form the staple diet for many common pet turtles. However, not all feeders are created equal. The best ones for turtles often feature key characteristics like moisture resistance to combat the humid tank environment, precise portion control to prevent overfeeding, and robust design to handle larger pellets.
In this guide, we’ll dive into 4 of the best automatic fish feeders on the market, exploring their features and helping you decide which is the perfect fit for your aquatic pets, be they fish, turtles, or both.
🐢 Can You Use an Automatic Fish Feeder for Turtles?
- Yes, for dry pellet-based turtle diets
- Not suitable for fresh greens or live food
- Moisture resistance is critical
- Portion control matters more for turtles (messier eaters)
🐸 Can Automatic Fish Feeders Be Used for Other Aquatic Pets?
Absolutely. They can be used for:
- Aquatic turtles
- Newts
- Axolotls (if pellet-fed)
- Certain crustaceans
Works best for dry pellet/granule diets only.
🧠 Why Consider an Automatic Fish Feeder?
Auto fish feeders offer several advantages:
- Consistent Feeding: Maintain a regular feeding schedule, crucial for fish and turtle health.
- Convenience: Ideal for busy individuals or frequent travelers.
- Portion Control: Prevent overfeeding, which can lead to water quality issues.

Reviews
“Great product, it works as advertised and it is very simple to configure. Also, the vendor is awesome too, recently I had an issue with my device and they replaced it immediately.”
“I needed a way to feed my small aquarium for 10 days. This will do the trick when using flake type of food. I only used it on batteries and it worked perfectly. Suggestion test the food output using the manual mode over a plate or other container and adjust the settings before actual use. Did not work well for the pellet type food, as it dispenses a lot because you need to open the setting wide for that type to dispense and it dispenses a lot.”

Reviews
“I purchased 2 of these feeders for my 2 small fresh water tanks (10 & 20 gallon) and I am very happy with them. I have used them on 2 trips so far and they worked perfectly. The feature I like best is the portion control, I have used other types of feeders and found it difficult to adjust them for smaller portion sizes. No problem with this model, just add the amount of food to be dispensed per portion and the unit delivers it. The device is easy to program and after charging the units they were ready to go. I highly recommend these!“
“Love, love, love this feeder. I’ve had automatic feeders in the past that dumped massive amounts of food in the water! This one doesn’t. I only have one betta and his portion needs are not massive. This feeder allows daily feedings or every other day. I tend to feed every other day when traveling so the water doesn’t get murky. I charged it upon receipt and 3 weeks later it still doesn’t need charging. It fits rimmed or rimless aquariums. No complaints. Excellent purchase“
