Technical Field
[0001] This invention relates to the field of indoor landscaping technology, specifically a method for raising ornamental fish without requiring a filter and without needing to change the water for extended periods. Background Technology
[0002] With the continuous improvement of the demand for quality living environment, indoor landscape and micro-landscape products have been widely used and developed due to their ability to create a natural ecological atmosphere in indoor spaces and meet people's needs to get close to nature. These products often use small organisms such as flowers, birds, fish and insects to create a water-land symbiotic landscape with natural elements such as water and rocks. They can also integrate elements such as architectural sculptures and power devices to enrich the humanistic and artistic effects. Among them, the ornamental fish ecological fish pond that integrates aquatic and terrestrial landscapes is one of the mainstream landscape products. In natural ecosystems, material cycling and ecological self-sustainability can be achieved through a complete closed loop of producers, consumers, and decomposers, without much external human intervention. However, existing ornamental fish ponds generally have the following defects: poor water and material circulation between the aquatic and terrestrial areas, the need for regular artificial watering of terrestrial plants, and the need for frequent water changes in the aquatic area. They also rely on complex external filtration systems to clean fish and shrimp feces, uneaten feed, and other waste, which not only increases the structural complexity, energy consumption, and manufacturing cost of the equipment, but also has the problems of high maintenance threshold and poor universality. They are very prone to water quality deterioration, plant withering, and landscape ecological collapse due to improper maintenance, making it difficult to achieve long-term stable intervention-free operation. Summary of the Invention
[0003] The purpose of this invention is to provide a method for raising ornamental fish without a filter and without needing to change the water for a long time, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for raising ornamental fish without a filter and without needing to change the water for a long time, comprising the following steps: Step 1, constructing the tank body and basic support; Step 2, constructing the terrestrial aquascape; Step 3, constructing the water circulation system; Step 4, constructing the aquascape; Step 5, deploying a timed lighting system; Step 6, maintenance-free self-circulating operation; In step one above, a breeding tank is made of high-transparency glass, and a vertical support structure and a bottom bed structure are set inside the tank. A support cabinet is set at the bottom of the tank. In step two above, a terrestrial landscaping base is built above the vertical support structure to create a simulated terrain. An installation groove is reserved on the terrestrial landscaping base, and a planting pot is placed in the installation groove. Terrestrial plants are planted in the planting pot. Stones are used on the surface of the terrestrial landscaping base to simulate mountain walls and shorelines, and ornamental sculpture models are arranged. In step three above, a water collection groove and pipe channel are reserved on the terrestrial landscaping substrate, a submersible pump is installed in the tank, a water supply pipe is installed at the output end of the submersible pump, the water supply pipe is installed into the pipe channel, and the output end of the water supply pipe is connected to the water inlet of the water circuit. An atomizer is set in the water collection groove, a water-retaining medium is laid on the surface of the terrestrial landscaping substrate, and moss is planted on the water-retaining medium. In step four above, aquatic plants are planted on the substrate structure inside the tank, water is poured into the tank until the water surface is level with the shore base of the terrestrial landscaping substrate, and then aquatic organisms are introduced, and a compound probiotic community is introduced into the water. In step five above, a timed illumination system is deployed above the cylinder block; In step six above, the submersible pump, atomizer, and timed illumination system are activated. The submersible pump delivers water from the tank to the water inlet, and the water flows back into the tank along the waterway. The atomizer uses the internal circulating water to create a mist effect, while simultaneously increasing the humidity required for the growth of terrestrial plants. The timed illumination system simulates the natural daylight cycle, providing photosynthetic conditions for both aquatic and terrestrial plants and maintaining the stability of the food chain's material cycle.
[0005] In step one, the vertical support structure is a transparent glass plate that is vertically fixed to the bottom of the cylinder. The bottom bed structure includes a crushed stone support plate, a crushed stone layer and natural stones. The crushed stone support plate is laid on the bottom of the cylinder, the crushed stone layer is laid on the crushed stone support plate, and the natural stones are placed on the crushed stone layer.
[0006] In step two, the terrestrial landscaping substrate is prepared by molding polyurethane rigid foam. The simulated terrain includes one or more combinations of mountains, caves, rivers, waterfalls, waterfronts, bridges, and islands, with rivers and waterfalls forming waterways.
[0007] In step three, the water collection groove is set at the mountain valley and island location of the simulated terrain. One end of the pipeline channel is connected to the water inlet of the waterway, and the other end is connected to the tank. The water inlet of the waterway is set at the top of the terrestrial landscape mountain. The main outlet of the waterway is connected to the tank, and the tributary outlet is connected to the water collection groove.
[0008] In step three, the water-retaining medium is sphagnum moss, which forms a capillary network to guide the water flowing through the waterway to the terrestrial plants.
[0009] In step four, the aquatic organisms include small fish and cleaner shrimp, wherein the small fish are one or more combinations of loach, golden algae eater, neon tetra, and discus fish, and the cleaner shrimp are candy shrimp.
[0010] Among the small fish, the ratio of discus fish, neon tetras, algae-eating squid, and loach is 1:6-10:1-2:1-2, preferably 1:8:1:1, and the ratio of the total number of small fish to the number of clean shrimp is 1:3-5, preferably 1:3.
[0011] In step four, the compound probiotic community includes Bifidobacteria and Lactobacillus. The ratio of Bifidobacteria to Lactobacillus is 1:3 to 1:10, preferably 1:6, based on the number of live bacterial colonies (CFU).
[0012] In step five, the timed illumination system includes a lamp holder, a tri-color lamp, and a timer. The lamp holder is mounted on the cylinder block, and the tri-color lamp and timer are mounted on the lamp holder. The tri-color lamp and the timer are electrically connected, and the illumination range of the tri-color lamp covers the entire cylinder block.
[0013] In step six, the producers of the ecological chain are aquatic plants and terrestrial plants, the consumers of the ecological chain are aquatic organisms, and the decomposers of the ecological chain are complex probiotic communities.
[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention constructs an integrated water-land structure, a closed-loop water circulation system, and a complete ecological chain, opening up channels for the flow of water and land materials. The capillary network of sphagnum moss enables automatic water supply to terrestrial plants. Probiotics decompose organic matter such as fish and shrimp excrement. Through plant photosynthesis, the plant achieves growth while simultaneously purifying the water body. There is no need to configure filters or frequently change the water. Only the 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 landscapes that require frequent artificial intervention and cannot achieve self-circulation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see the appendix Figure 1 The present invention provides an embodiment of a method for raising ornamental fish without a filter and without needing to change the water for a long time, comprising the following steps: Step 1, constructing the tank body and basic support; Step 2, constructing the terrestrial aquascape; Step 3, constructing the water circulation system; Step 4, constructing the aquascape; Step 5, deploying a timed lighting system; Step 6, maintenance-free self-circulating operation. In step one above, a breeding tank is made of high-transparency glass. A vertical support structure and a bottom bed structure are set inside the tank, and a support cabinet is set at the bottom of the tank. The vertical support structure is a transparent glass plate that is vertically fixed to the bottom of the tank. The bottom bed structure includes a gravel support plate, a gravel layer and natural stones. The gravel support plate is laid at the bottom of the tank, the gravel layer is laid on the gravel support plate, and the natural stones are placed on the gravel layer. In step two above, a terrestrial landscaping base is constructed above the vertical support structure to create a simulated terrain. Installation slots are reserved on the terrestrial landscaping base, and planting pots are placed in the installation slots to plant terrestrial plants. Stones are used on the surface of the terrestrial landscaping base to simulate mountain walls and shorelines, and ornamental sculpture models are arranged. The terrestrial landscaping base is made of polyurethane rigid foam and the simulated terrain includes one or more combinations of mountains, caves, rivers, waterfalls, waterfronts, bridges, and islands, with rivers and waterfalls forming waterways. In step three above, water collection grooves and pipe channels are reserved on the terrestrial landscaping substrate. The water collection grooves are set at the mountain valleys and islands of the simulated terrain. One end of the pipe channel is connected to the water inlet of the water system, and the other end is connected to the tank. The water inlet of the water system is set at the top of the mountain of the terrestrial landscaping. The main outlet of the water system is connected to the tank, and the tributary outlet is connected to the water collection groove. A submersible pump is installed in the tank, and a water supply pipe is installed at the output end of the submersible pump. The water supply pipe is inserted into the pipe channel, and the output end of the water supply pipe is connected to the water inlet of the water system. An atomizer is set in the water collection groove. A water-retaining medium is laid on the surface of the terrestrial landscaping substrate, and moss is planted on the water-retaining medium. The water-retaining medium is sphagnum moss, which forms a capillary network to guide the water flowing through the water system to the terrestrial plants. In step four above, aquatic plants are planted on the substrate structure inside the tank, and water is poured into the tank until the water surface is level with the shoreline of the terrestrial aquascape substrate. Then, aquatic organisms are introduced, and a compound probiotic community is introduced into the water. The aquatic organisms include small fish and cleaner shrimp. The small fish are loach, algae eater, neon tetra, and discus fish, and the cleaner shrimp are candy shrimp. The ratio of discus fish, neon tetra, algae eater, and loach is 1:8:1:1, and the ratio of the total number of small fish to the number of cleaner shrimp is 1:3. The compound probiotic community includes bifidobacteria and lactic acid bacteria. Calculated by live bacterial colony count (CFU), the ratio of bifidobacteria to lactic acid bacteria is 1:6. In step five above, a timed illumination system is deployed above the cylinder block. The timed illumination system includes a lamp holder, a tri-color illuminator, and a timer. The lamp holder is installed on the cylinder block, and the tri-color illuminator and the timer are installed on the lamp holder. The tri-color illuminator and the timer are electrically connected, and the illumination range of the tri-color illuminator covers the entire cylinder block. In step six above, the submersible pump, atomizer, and timed illumination system are activated. The submersible pump delivers water from the tank to the water inlet, and the water flows back into the tank along the waterway. The atomizer uses the internal circulating water to create a mist effect, while simultaneously increasing the humidity required for the growth of terrestrial plants. The timed illumination system simulates the natural daylight cycle, providing photosynthetic conditions for both aquatic and terrestrial plants and maintaining the stability of the material cycle in the food chain. The producers in the food chain are aquatic and terrestrial plants, the consumers are aquatic organisms, and the decomposers are a complex probiotic community.
[0018] Based on the above, the advantages of this invention are as follows: When in use, an aquatic environment is constructed using a high-transparency glass tank. A polyurethane foam-molded terrestrial landscaping substrate is supported by a vertically transparent glass plate inside the tank, forming a seamless symbiotic space connecting water and land. A submersible pump inside the tank powers a closed-loop water circulation system, transporting water to the top of the terrestrial landscaping and then naturally flowing back into the tank along pre-designed channels and waterfalls. The return flow process simultaneously oxygenates the water. Furthermore, the sphagnum moss covering the entire surface of the landscaping forms a capillary network, evenly guiding the circulating water to irrigate all terrestrial plants. No artificial watering or independent water supply system is required. The accompanying atomizer directly draws from the circulating water to achieve humidity control and landscape effects. Based on the cycle, the system constructs a complete three-level ecological chain that matches the microenvironment. Aquatic and terrestrial plants are the producers, and a timed lighting system simulates the natural day cycle to ensure photosynthesis, synthesizing inorganic matter in the water into organic matter needed for their own growth, while simultaneously purifying the water and releasing oxygen. Small fish and cleaner shrimp in a fixed ratio are the consumers, feeding on aquatic algae, plankton, and a small amount of artificial feed. Their metabolic waste and uneaten feed are the source of organic matter. Bifidobacteria and lactic acid bacteria are the decomposers, spreading throughout the water cycle, gradually fermenting and decomposing organic matter into inorganic substances such as nitrogen, phosphorus, and potassium that can be absorbed and utilized by plants, and then supplying them back to the producers to complete the closed-loop transformation of matter.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
