The invention provides an aquatic animal and plant symbiotic device. The aquatic animal and plant symbiotic device comprises a water body container, a planting container fixed above the water body container and an air pump, wherein an air outlet pipe of the air pump penetrates through the bottom surface of the water body container to introduce air into a water body, a first filter device is connected to the upper side of the air outlet pipe, a second filter device is arranged between the planting container and the water body, and is connected with the planting container. The aquatic animal and plant symbiotic device has the beneficial effects that the air pump disposed at the bottom of the water body container is used for supplying oxygen to plants, aquatic animals and microorganism bacteria in water; the air pump is matched with the two filter devices to achieve reverse air-lift effect, and finally, the purposes of achieving water circulation and purification and decomposition of remnant food, aquatic animal wastes and rotten plant root systems, and thus supplying nutrients to the plants can be achieved, organic matter and fertilizers on the top are utilized to supply balanced nutrition to the plants, and organic planting is achieved.
