This invention discloses a method for raising ornamental fish without filters and without the need for long-term water changes, comprising the following steps: Step 1, constructing the tank and basic support; Step 2, constructing terrestrial landscaping; Step 3, constructing a water circulation system; Step 4, constructing aquatic landscaping; Step 5, deploying a timed lighting system; Step 6, maintenance-free self-circulating operation. This invention, by constructing an integrated terrestrial and aquatic structure, a closed-loop water circulation system, and a complete ecological chain, opens up channels for the flow of materials between water and land. Terrestrial plants are automatically supplied with water through a capillary network of sphagnum moss. Probiotics decompose organic matter such as fish and shrimp excrement, and the plants achieve self-purification of the water through photosynthesis. No filters or frequent water changes are required; only replenishment of water lost through natural evaporation and a very small amount of artificial feeding are needed to maintain ecological balance and landscape stability in the long term. This completely solves the pain points of traditional indoor landscaping, which requires frequent artificial intervention and cannot achieve self-circulation.

This invention relates to the field of space life science technology, and in particular to a microgravity environment simulation closed cultivation device and control system that combines multi-axis control and acoustic levitation. The device includes two sets of vertical slide rail mechanisms, on which a first rotary servo motor is slidably mounted, driving an outer rotating frame to rotate along a first direction. A second rotary servo motor is fixed to the outer rotating frame, driving a cultivation chamber connected to an inner rotating frame to rotate along a second direction. An acoustic levitation device is installed inside the cultivation chamber. This invention introduces random gravity disturbances through random sliding of the slide rails, combined with dual-axis random rotation, to construct a microgravity environment coupled with both random gravity and rotational speed.
