Do goldfish need light? Well, how would you like to be kept in the dark?!

Like most animals, goldfish would not be healthy if permanently kept in dark conditions.

Unlike some fish that live deep in the sea, wild goldfish live in lakes and rivers. These relatively shallow waters are often illuminated by quite bright daylight. Therefore, the lighting conditions in your aquarium should replicate this natural environment as closely as possible.

Key Takeaways:

  1. Goldfish Need Light: Goldfish thrive with natural lighting, replicating their natural habitat in lakes and rivers.
  2. Too Much Light Can Be Harmful: Avoid direct sunlight to prevent overheating and algae growth.
  3. Color and Behavior Impact: Insufficient light can cause goldfish to lose color and appear unhealthy.
  4. Day-Night Cycles: Proper light and darkness maintain healthy sleep and eating habits for goldfish.
  5. Aquarium Lighting: If your tank is in a dark area or for plant growth, use an aquarium light but turn it off at night.
  6. Goldfish Vision: Goldfish can’t see in the dark and rely on smell and vibrations to navigate at night.
