Here's why:
* Breeding: Guppies are popular for breeding, and having both sexes allows for successful reproduction. Pet stores often sell them in pairs or small groups to encourage breeding.
* Appearance: Male guppies are known for their vibrant colors and elaborate fins, making them attractive to buyers. Female guppies are generally more muted in color but still desirable for their role in breeding.
* Variety: Pet stores aim to offer a variety of fish options, and both male and female guppies contribute to this diversity.
It's worth noting that:
* Some pet stores may specialize in certain types of guppies (e.g., show-quality males) and may have a limited selection of females.
* You can often request specific sexed guppies from a pet store, especially if they are involved in breeding.
If you are unsure about the sex of a guppy, ask the pet store staff for assistance. They should be able to help you distinguish between males and females based on their physical characteristics.
