The Impact of Artificial Light on Fish: What You Need to Know

Fish in blue light

A recent study by the Max Planck Institute of Animal Behavior found that artificial light, particularly blue light at night, disrupts fish biology and can pass down negative effects to their offspring. The research showed that exposure to blue-spectrum lighting at night impacted fish sleep cycles, behavior, and immune function, leading to long-term health issues.



Here’s how you can help your fish:


  1. Turn Off Aquarium Lights at Night: Use a timer to maintain a natural light-dark cycle.

  2. Limit Exposure to Room or Outdoor Lights: Keep the tank away from constant artificial lighting.

  3. Use Low-Impact Lighting: If nighttime lighting is needed, choose dim, blue-spectrum lights sparingly.

  4. Provide Hiding Spots: Give your fish places to retreat from light, like plants or rocks.


By managing their light exposure, you’ll protect your fish’s health and create a more natural, stress-free environment for them and their future offspring.
