What are fancy-tail guppies?

Fancy-tailed guppies, also known as fan-tailed guppies, are a popular species of freshwater fish named for their colorful, fan-shaped tails. Male fancy-tailed guppies have the biggest, most colorful tails.

Fancy-tailed guppies are inexpensive and easy to care for. They prefer to be in schools with other guppies. When set up for breeding, the school should contain more females than males. Identifying the gender of these fish is easy — females are bigger and drab in color, while males are smaller and brightly colored. All guppies give birth to live fry. Fan-tailed guppies get along with most other nonaggressive aquarium fish.
