You can buy marimo moss balls in a lot of the same places as you can betta fish. Look in big pet stores like Petco and PetSmart, aquarium forums, local aquatic stores, and online.

When buying them in person make sure to inspect for signs of health (e.g. bright green color).

Then I started thinking about how these aquatic plants actually get to pet stores, like brick-and-mortar pet stores, and realized that it was no different than having it shipped straight to my door. In fact, I can’t see how it would be would be anything less than beneficial to the moss ball to cut out the middleman of the brick-and-mortar store and have the life aquatic plant delivered straight to me.
