Sleep deprivation in fish can lead to a variety of health issues, including a weakened immune system, poor digestion, and stunted growth. In the wild, fish rely on natural light cycles to regulate their sleep patterns.
When kept in a tank, it’s important to replicate these cycles by providing them with a consistent light schedule. This includes turning off the blue light at night to mimic the darkness they would experience in their natural environment.
Leaving the blue light on at night can also disrupt the natural circadian rhythm of your fish, leading to confusion and stress. This can cause your fish to become disoriented and make it difficult for them to differentiate between day and night.
To keep your fish happy and healthy, it’s best to stick to a consistent light schedule and turn off the blue light at night to allow them to get the quality rest they need.
