- Water Conditions: Pink Tuxedo Guppies are adaptable to a wide range of water conditions. They thrive in temperatures between 72°F and 82°F (22°C to 28°C) and prefer a slightly alkaline to neutral pH level of 7.0 to 7.5. Good water filtration, regular water changes, and maintaining stable water parameters are important for their overall health.

- Tank Size and Setup: Provide a well-sized aquarium for Pink Tuxedo Guppies, as they are active swimmers. A tank size of at least 10 gallons (38 liters) is recommended for a small group of guppies. Decorate the aquarium with live or artificial plants, driftwood, and hiding places. An open swimming area should also be available for their natural behavior.

- Tank Mates: Pink Tuxedo Guppies are generally peaceful and can coexist with other peaceful community fish. Suitable tank mates include other guppy varieties, tetras, rasboras, and peaceful catfish species. Avoid housing them with aggressive or fin-nipping fish that may stress or harm them.

Supplement their diet with live or frozen foods such as brine shrimp, daphnia, and bloodworms to provide essential nutrients and enhance their coloration.

- Breeding: Pink Tuxedo Guppies are known for their prolific breeding behavior. They are livebearers, meaning they give birth to fully-formed fry. Breeding can occur easily in a well-maintained aquarium, but it's recommended to separate pregnant females into a breeding box to protect the fry. Provide plenty of hiding places for the fry to ensure their survival.

- Care and Behavior: Pink Tuxedo Guppies are relatively easy to care for, making them suitable for beginner aquarists.
