When I decided to buy a 3-gallon tank with a filter, I first considered my specific needs. I wanted a tank that would be easy to maintain yet provide a healthy environment for my aquatic pets. I also thought about the type of fish I wanted to keep and how many would comfortably fit in a 3-gallon space.

Choosing the Right Filter
