Can guppies live without a light?
Guppies are freshwater fish and can live without light, however, they will be less active without a light source and their colors will not be as vibrant. If you choose to not have a light on in your aquarium, it is important to provide hiding places for your guppies so they feel secure.
Do guppies need a heater?
Guppies are tropical fish and as such prefer water temperatures between 72-82 degrees Fahrenheit. While they can survive in cooler water for a short period of time, prolonged exposure to cooler temperatures can lead to health problems such as stress and disease.
For this reason, it is generally recommended that guppies be kept in an aquarium with a heater.
Can guppies be in the dark?
Guppies are a species of freshwater fish that are often kept as pets. They are known for their brightly colored bodies and their active, playful nature.
Guppies are typically found in tropical climates and prefer waters that are warm and well-oxygenated.
While guppies can technically survive in the dark, it is not ideal for their long-term health and wellbeing. Guppies are active, social creatures that rely on vision to navigate their environment and find food.
In the wild, guppies typically inhabit waters that are well-lit by the sun. In captivity, guppies should be kept in an aquarium that is similarly well-lit.
Without sufficient light, guppies may become lethargic and stop eating. They may also become more susceptible to disease and parasites.
For these reasons, it is generally not recommended to keep guppies in the dark.

Do guppies sleep on the bottom of the tank?
Guppies sleep on the bottom of the tank because they are trying to stay away from predators. By sleeping on the bottom, they are less likely to be seen by predators.
What do guppies do at night?
Guppies are active during the day and night, although they may be more active during the day. At night, guppies may rest in plants or hide in caves.
Do guppies like led lights?
Different guppies may prefer different types of lighting. However, many aquarists find that led lights are a good option for guppy tanks as they are energy efficient and produce little heat.
Led lights also come in a variety of colors, which can add to the aesthetic of the aquarium.

Do guppies like blue light?
Guppies are a species of freshwater fish that are typically found in tropical regions. They are a popular choice for aquariums and fish tanks due to their vibrant colors and small size.
Guppies are known to be attracted to blue light, and many aquarium owners use blue LED lights to create a more aesthetically pleasing environment for their fish. While there is no scientific evidence to support this claim, it is believed that the blue light helps to bring out the colors of the guppies and makes them more visible in the water.
Do guppies sleep at top of the tank?
Guppies are a type of freshwater fish that are known to be active during the day. As such, they typically sleep at the bottom of the tank where it is darker and quieter.
However, there have been reports of guppies sleeping at the top of the tank. This is likely due to the fact that guppies are able to adjust their sleep patterns to accommodate their environment.
If the tank is well-lit and there is a lot of activity near the top of the tank, guppies may choose to sleep at the top in order to avoid commotion.
Can guppies see in the dark?
Guppies are able to see in low light conditions, but they do not have good night vision. Their eyes are adapted to detect movement in their environment, which helps them to avoid predators.
Do guppies need to be in groups?
Guppies are social fish and do best when kept in groups. A single guppy can become stressed and may not thrive.
In the wild, guppies live in large groups and are constantly interacting with other fish. When kept in captivity, guppies should be kept in groups of at least 5 fish.
Do guppy fry need light?
Guppy fry typically need light in order to see and find food. However, too much light can be harmful to them and cause them to overheat, so it is important to provide them with a balance of light and darkness.
How do guppies sleep?
Guppies sleep in a state of rest called a torpor. In this state, their metabolic rate and body temperature drop significantly.
This allows them to conserve energy and survive in environments with little food or water.
Conclusions
Some people believe that guppies need light at night, while others believe that they do not. There is no clear consensus on this matter.
Some people say that guppies need light at night so that they can see their food, while others say that guppies do not need light at night because they are not active during this time.
