How do you breed fan tail fish?

To breed fancy tail fish, such as guppies or bettas, start by setting up a separate breeding tank with clean, warm water and plenty of hiding spots. Introduce a male and female of the desired species, ensuring they are healthy and of breeding age. Once the female is ready, she will display signals of receptiveness, and spawning will occur. After spawning, remove the adults to protect the fry, and maintain optimal water conditions for the developing eggs and young fish.
