Do guppies have night vision
What do guppies do at night?
Guppies are diurnal fish, meaning they sleep at night when it’s dark. Like most fish, guppies don’t have eyelids, making it difficult to tell they are sleeping. Scientists know very little about the sleep cycles of fish, but believe the purpose of a night’s rest is to conserve energy. (source)
Do guppies need a light on at night?
No, guppies don’t need light at night. Guppies need darkness to sleep and rest properly. Having the aquarium lights on all the time may result in poor sleep quality, sickness, and eventually, death. Guppies need six to eight hours of sleep each day and thus, you should keep the lights off for the same amount of time. (source)
Do guppies like lights?
Yes, if you’re going to look after guppies, then they definitely need light. Just like humans, guppies have a circadian rhythm, so they need light to figure out when to sleep and when to wake up. So if you’re going to house guppies in your aquarium, make sure you have a light for them as well. (source)
How many hours do guppies sleep?
Around 6-8 hours. This is because, just like us, guppies go to sleep when the sun goes down, and wake up again when the sun rises. Or in the case of the fish tank, when you turn the light on and when you turn the light off. (source)
How do I know if my guppies are happy?

What do guppies like in their tank?
Guppies are not picky eaters and will even graze on algae growing inside the aquarium. We like to give ours a wide variety of foods, such as bloodworms, brine shrimp, flake foods, pellets, and Easy Fry and Small Fish Food. (source)
Why do guppies swim at the top of the tank?
They get their oxygen by passing water through their gills. The gills separate the oxygen from the rest of the water. When something happens that makes it difficult for the guppies to separate oxygen from the water, then they start to suffocate. As a result, they swim to the surface to gulp in the air instead.
