Can hydroponic epipremnum aureum be used to raise fish?
In the trend of indoor green plant landscaping, the symbiotic system of hydroponic epipremnum aureum and ornamental fish has attracted much attention. This ecological combination can purify the air and add vitality, but to achieve harmonious coexistence of plants and fish, it is necessary to master scientific water quality management methods. This article will analyze the secrets to successfully raising fish in the hydroponic epipremnum aureum system from three dimensions: spatial configuration, ecological balance, and maintenance skills.
The feasibility of hydroponic epipremnum aureum and fish symbiosis
Golden ratio of space capacity to number of fish
It is recommended to have 1cm of fish body length per liter of water, with 3-5 small fish in a 30cm high container being ideal. For example, smaller tropical fish species like zebra fish and guppy fish are more suitable for the symbiotic system. The container depth should be maintained at 20cm or more to provide ample space for the roots and fish.
Scientific methods for maintaining water quality
Use the segmented water replacement method: replace 1/3 of the water every week, using tap water that has been exposed to sunlight for 24 hours. Adding a nitrifying bacteria culture solution can establish a biological filtration system, with actual measurement data showing a 65% reduction in ammonia nitrogen content. The water temperature should be kept stable between 22-28°C to avoid sharp fluctuations.
Ecological benefits of the epipremnum aureum symbiotic system
Landscape aesthetics and ecological balance
The aerial roots of epipremnum aureum can form a natural filter net, which has been experimentally proven to absorb 30% of the suspended matter in the water. The transpiration of the leaves increases the humidity of the air, which is especially suitable for fish species like paradise fish that thrive in moist environments. It is recommended to keep 1/3 of the water surface space to ensure efficient oxygen exchange.
Symbiotic mechanism of nutrient recycling
Fish excrement is decomposed into nitrates, of which epipremnum aureum can absorb 80% of the nutrients. When adding water-soluble fertilizers regularly, a special formula for fish should be chosen to avoid heavy metal components like copper and zinc.
Key points of caring for the symbiotic system
Disease prevention and daily management
Soaking the roots in 3% salt water for 5 minutes every month can prevent root rot. Rotting leaves should be removed immediately to avoid polluting the water quality. It is recommended to use LED grow lights, with 6-8 hours of light per day to increase the photosynthetic efficiency of epipremnum aureum by 42%.
Seasonal adjustment techniques
In winter, a constant temperature heating rod is needed, and in summer, direct sunlight should be avoided. Regularly monitor key indicators such as pH (6.5-7.5) and ammonia nitrogen content (＜0.02mg/L) using a water quality testing instrument.
A successful hydroponic epipremnum aureum fish-raising system is a perfect combination of technology and nature. Through precise control of breeding density, regular water quality testing, and reasonable lighting management, long-term stability of the ecosystem can be achieved. It is recommended for beginners to start with low-maintenance fish species and gradually master the art of balancing the symbiotic system.
