Phil is an Editor at LittleThings. He loves writing and the outdoors. You can often find him at the movies or the park.

One of my absolute favorite types of fish is the betta fish. Recently, my nephew won a betta fish in a school carnival and he gave him to me as a gift, and so I brought him home.


Well, not home exactly. I brought him back to the LittleThings office to be our official office pet, Kevin. In an effort to create a great home for Kevin, I decided to make him a beautiful DIY Mason jar fish tank — a project I had seen recommended in various pet stores. This project was so simple and the results were really lovely, just like when I made a Mason jar photo holder.

All I needed was a liter-sized Mason jar, aquarium gravel, some decorations, betta fish food, special betta fish drops for the water, and Kevin himself.


Male betta fish actually enjoy small spaces as long as they are at least one liter in size, making the jar a perfect choice.

This simple DIY project took no time at all. It is the perfect project for yourself, or something fun and easy you could try with your niece, nephew, or any other kids in your life.
