Without a doubt, most adorable plants for any fish tank are Marimo Moss Balls. These balls of algae keep the water clean by filtering out toxic chemicals. Have a few of these in your aquarium for your Betta fish to play with. Always make sure there is a small current of water rotating the moss balls as they need to catch sunlight from every side for photosynthesis.
