Guppies swimming at the top of the tank could indicate a few things. It might be a sign that the water in the tank is low in oxygen, prompting the guppies to swim closer to the surface to breathe. It could also be a sign of stress or discomfort caused by poor water quality, high ammonia levels, or improper temperature. It's important to monitor the water parameters, ensure proper aeration, and check for any signs of illness or disease in the guppies. **

Yes, Endler guppies can be crossed with regular guppies. Both Endler guppies and regular guppies belong to the same species, Poecilia reticulata, and are capable of interbreeding. However, it is important to note that hybridizing these two types of guppies can result in a loss of the distinct traits and characteristics of the original Endler guppies. Additionally, hybridization can also lead to genetic dilution and potential health issues in the offspring. **

Guppies need a steady supply of water fleas to thrive in their environment. The exact number of water fleas needed can vary depending on the size and number of guppies in the tank. As a general guideline, it is recommended to provide a few water fleas per guppy each day to ensure they have enough food to sustain them. It is important to monitor the guppies' behavior and adjust the amount of water fleas accordingly to ensure they are getting enough to eat. **

Guppies may be swimming in one corner of the tank due to various reasons such as poor water quality, lack of oxygen, high ammonia levels, or overcrowding. It could also be a sign of stress or discomfort caused by aggressive tank mates, inadequate hiding spots, or sudden changes in water parameters. It is important to monitor the tank conditions, ensure proper filtration and aeration, and provide a suitable environment for the guppies to thrive and exhibit natural behavior. **

Guppies are tropical fish and are not well-suited to cold water temperatures. They thrive in water that is between 22-28°C. Exposing guppies to water that is 10°C could lead to stress, illness, and even death. It is important to provide guppies with the appropriate water temperature to ensure their health and well-being. **

Yes, you can keep 2 male Guppies and 2 female Guppies together in a tank. It's important to have a balanced ratio of males to females to prevent aggression and stress among the fish. Guppies are social fish and will thrive in a community tank with a mix of males and females. Just be mindful of the tank size and provide plenty of hiding spots and plants for the females to seek refuge if they need a break from the males' attention. **

When you cross normal guppies and Endler guppies, you get a hybrid of the two species. The resulting offspring may display a combination of traits from both parent species, such as coloration, pattern, and fin shape. This hybridization can lead to increased genetic diversity and potentially produce unique and desirable characteristics in the offspring. However, it's important to note that hybridization can also lead to genetic dilution and loss of purebred traits in the long run. **

Endler Guppies prefer soft water, as it more closely resembles their natural habitat in the streams and rivers of Venezuela. Soft water typically has a lower mineral content and a slightly acidic pH, which is ideal for these fish. Hard water, on the other hand, can be stressful for Endler Guppies and may lead to health issues. Therefore, it is better to provide them with soft water in their aquarium. **
