Answer 15

Fish, like any other living creatures, require a balance of light and darkness to maintain a healthy natural rhythm. While fish do not necessarily need lights off at night, providing a period of darkness is beneficial for them. Here are a few reasons why:

Circadian Rhythm: Fish, like many organisms, have an internal biological clock that regulates various physiological processes. Exposing fish to regular periods of light and darkness helps maintain their natural circadian rhythm, which promotes overall well-being and normal behavior.

Stress Reduction: Providing a period of darkness at night allows fish to rest and reduce stress. Continuous exposure to bright light can disrupt their natural behavior and stress them out, potentially leading to health issues.
