Sunset Guppies are a specific color variant of the popular Guppy fish (Poecilia reticulata). Here's some information about them:

1. Appearance: Sunset Guppies are known for their vibrant and eye-catching coloration. They typically have a sunset-like gradient of colors, with shades of orange, yellow, and sometimes red or pink blending together. Their fins may also display similar coloration, often with patterns such as spots or stripes.

2. Size: Like other Guppies, Sunset Guppies are relatively small fish, typically reaching lengths of about 1.5 to 2.5 inches (3.8 to 6.4 cm) when fully grown.

3. Behavior: Sunset Guppies are generally peaceful and social fish, making them suitable for community aquariums. However, males may exhibit some territorial behavior, especially when competing for the attention of females.

4. Tank Requirements: Sunset Guppies 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. Adequate filtration and regular water changes are essential for maintaining water quality.

5. Diet: Sunset Guppies are omnivores and will accept a variety of foods, including flakes, pellets, frozen foods, and live foods such as brine shrimp and bloodworms. Providing a varied diet will help ensure their health and enhance their coloration.

6. Breeding: Like other Guppies, Sunset Guppies are prolific breeders and relatively easy to breed in captivity. They are livebearers, meaning females give birth to free-swimming fry instead of laying eggs. Providing hiding spots for fry or separating them from adults is important for their survival.

7. Tankmates: Sunset 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 maintenance, including water changes, filter cleaning, and monitoring water parameters, is essential for keeping Sunset Guppies healthy. They are relatively hardy fish but still require proper care to thrive.
