Do fish like it dark at night?
Fish don’t like the dark because when there is no light to see, they dart around the tank, colliding with the walls, ornaments and can even become tangled in the plants. Fish need light to determine whether it is night or day, and they’re scared of the sudden switch from darkness to light.
Do fish need lights off at night?
Aquarium fish do not need light and it is best that you turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.
Do fish see night?
Most fish can see in the dark due to evolved cone cells in fish eyes. But still, you must turn off the aquarium light for at least 12 hours to give fish time to rest. Some fish can see in the dark better than others because of differences in the number of cones present in each fish species.02.11.2021
