The Aquaponic Planter and Fish Habitat allow you to keep betta or goldfish together with your favorite houseplant or herbs. The symbiotic relationship between the plant and fish allows both to thrive in this fun and educational environment. Aquaponics is a great learning tool. The fish poop feeds the plant and the plant cleans the water for the fish. Recommended for betta, goldfish, bloodfin tetra, and white cloud minnow. Betta fish tank is easy to clean; planter is simple to remove when needed. Can be used as a planter alone for many water-thirsty plants.
