Other scientists believe that fish do perceive blue light at night the same way that humans do and that blue light at night can help fish to see better in low light conditions.
Summary
A study conducted in 2014 found that fish tend to be calmer in darker environments. The study was conducted by observing the behavior of fish in different lighting conditions, and it was found that the fish were less active and more subdued in darker areas.
This research suggests that darkness may have a calming effect on fish.
