The Pink Tuxedo Guppy is a popular aquarium fish known for its vibrant coloration and elegant appearance. Here's some information about them:

1. Appearance: Pink Tuxedo Guppies have a distinct pink coloration with black markings resembling a tuxedo pattern, which gives them their name. They typically have flowing fins and tails, adding to their attractiveness.

2. Size: They are relatively small fish, usually growing up to 1.5 to 2.5 inches (3.8 to 6.4 cm) in length.

3. Behavior: Guppies are generally peaceful and social fish, making them suitable for community aquariums. However, males can sometimes exhibit aggression towards each other, especially if they are competing for the attention of females.

4. Tank Requirements: Pink Tuxedo Guppies are hardy fish and can adapt to a wide range of water conditions. However, they thrive in well-maintained aquariums with a temperature range of 72-82°F (22-28°C) and a pH level between 6.8 and 7.8. They appreciate a planted tank with plenty of hiding spots and open swimming areas.

5. Diet: Pink Tuxedo Guppies are omnivores and will eat a variety of foods, including flakes, pellets, frozen foods, and live foods like brine shrimp and bloodworms. It's essential to provide them with a balanced diet to ensure their health and vibrant coloration.

6. Breeding: Guppies are prolific breeders, and breeding them is relatively easy. They are livebearers, meaning they give birth to free-swimming fry instead of laying eggs. If you keep male and female guppies together, chances are they will breed without much intervention. However, to prevent overpopulation, it's essential to either separate the fry or provide plenty of hiding spots for them to survive.

7. Tankmates: Pink Tuxedo Guppies are compatible with a wide range of peaceful fish species, including tetras, rasboras, mollies, and peaceful dwarf cichlids. Avoid keeping them with aggressive or fin-nipping fish that might harass them.

8. Maintenance: Regular water changes, proper filtration, and monitoring water parameters are crucial for keeping Pink Tuxedo Guppies healthy. They are relatively low-maintenance fish but still require regular care to thrive.

Overall, Pink Tuxedo Guppies are beautiful and easy-to-care-for fish that can add color and activity to any freshwater aquarium setup. With proper care, they can live for two to three years or more in captivity.
