One Pot, Two Lives | a planter and a fishtank in one to promote a beautiful example of simbiotic living. While the fish's waste provides nutrients for the plant, the plant filters the water that it is fed to provide clean water for the fish. Genius!
Interactive aquarium full of bioluminescent plankton called dinoflaggelates ("dinos"). The plankton illuminates the dinosaur-shaped environment when you gently shake it. Just let them bask in indirect light during the day, and they'll treat you to a soft blue light show at night.
