Xinyi Healing Method: 10 minutes of fish watching per day, dopamine secretion boosted by 40%

       In the urban jungle of reinforced concrete, a fish tank is quietly reconfiguring the boundary between man and nature. Xinyi Aquarium Research Institute 2024 data show that the global household fish tank ownership exceeded 210 million units, of which 72% keepers will raise fish as "spiritual needs" - this is not only the upgrading of the ornamental behavior, but also the technological civilization on the recoding of the life system. This is not only an upgrade of the ornamental behavior, but also the recoding of the life system by the technological civilization. As smart sensors replace traditional water thermometers, and algae control evolves into spectral wavelength calculations, we have to wonder: in the collision between the Internet of Things and ecology, are human beings observers outside the fish tank, or are they "brains in the tank" trapped in a larger system? This book attempts to deconstruct this duality, from the molecular warfare of water quality management to the neural intervention of light control, revealing the hidden technological philosophy and bioethics behind modern fish farming.

I. Light duration requirements

1. ‌basic criteria‌

   • ‌Daily Duration: Daily light is recommended to be controlled at8-10 hours, which can be achieved through a combination of natural and artificial light sources to avoid algae outbreaks caused by more than 12 hours of continuous light.
   • ‌time-sharing management: Indoor aquariums can besegmented lighting(e.g. 3 hours of natural light in the morning + 5 hours of artificial light in the afternoon), outdoor fish ponds can rely on natural light as the main source.

2. ‌Special scenario adjustments‌

   • ‌Breeding stage/juvenile stage: appropriate extension to10-12 hoursIt promotes metabolism and body color development;
   • ‌Disease recovery period: Reduced to4-6 hours, reducing environmental stimuli.

II. Light intensity control

3. ‌Natural light regulation‌

   • ‌Summer protection: Use a shade net to limit the light intensity to5500-5800 luxTo prevent direct sunlight from causing a sudden rise in water temperature;
   • ‌Winter fill light: The intensity of artificial light sources (e.g. metal halide lamps) needs to match the natural light, avoiding light sources below3000 luxTriggers fading.

4. ‌Artificial light source selection‌

   • ‌Luminaire type: PrioritizationFull Spectrum LED Lampsmaybe10000K color temperature metal halide lamp, simulates natural light color temperature;
   • ‌Mounting Height: Luminaires from the water surface30-50cmAvoid burning the fish with too much light.

III. Management of seasonal dynamics

5. ‌Summer Strategy‌

   • ‌shading: Outdoor pools are covered with shade netting, and indoor tanks avoid areas of strong midday light;
   • ‌time interval adjustment: Concentrate light hours in the early morning and late afternoon, avoiding the high temperatures between 11:00 and 15:00.

6. ‌Winter Strategy‌

   • ‌fill-in time: Artificial light sources are concentrated in9:00-16:00to make up for the lack of natural light in winter;
   • ‌Water temperature linkage: Synchronized monitoring of water temperature during the light period to ensure that it does not fall below15°C, avoiding the health effects of cold temperatures superimposed on low light.

IV. Health and aesthetic balance

7. ‌Body Color Maintenance‌

   • ‌Erythema intensification: At least daily6 hours.Medium intensity light (4000-5000 lux) to promote pigmentation;
   • ‌Fading Prevention: Weekly supplementation is required for prolonged low-light environments (<2000 lux).UVB lamp exposure for 2 hoursThe

8. ‌algae prevention and control‌

   • ‌intensity threshold: Light intensity over6000 luxor longer than12 hours.When this is the case, physical filtration needs to be enhanced or alga-removing organisms need to be introduced;
   • ‌cyclic blackout: Weekly setup1 day without light, inhibits algal blooms.

Recommendations for implementing norms and tools

Key Risk Alerts

• ‌excessive light: May lead to fish stress and uncontrolled algae, requiring timely intervention through shade nets or shorter hours;
• ‌spectral deviation: Non-full-spectrum fixtures are prone to fish discoloration fading with prolonged use, and it is recommended that fixture technology be upgraded every 2 years.
