What is the Best Automatic Fish Feeder for a Small Tank?

It is healthy for people to have emotional attachments. That is why it is important for people to surround themselves with pets and also plants if possible. I have a cat and two dogs and for some reason,

I decided to get a pet fish as well. Being new to taking care of fish, I had to go to the pet store and ask for advice from a friend or two. That is why I decided to share my newfound knowledge and write this review.

Factors to consider before purchasing automatic fish feeders:

Number of feedings per day

This is important because it helps you with your fish feeding schedule. The number of feeds goes a long way in determining the type of automatic fish feeder you choose.

At the end of the day, it’s important to pick a fish feeder which can help you accomplish the desired number of feeds per day.

Number of actual feeding days

If you tend to travel a lot or plan on going away, you might want to consider a fish feeder that will cater to your fish for the right amount of days till you come back.

Of course, large size will ensure that your fish remain in a tip-top condition even when you travel which means that you won’t have to worry about them while in a journey.


Ensure that the automatic fish feeder can handle the amount of food that will be enough for your fish.

The price

If you want to have something incredible, be sure to take note of the price. For the best results, I suggest that you pick a fish feeder whose price is considerable and convenient. However, don’t pick those half-baked and cheap knockoffs since that will highly affect the overall performance.
