* _Less aggressive than females._
* _Easier to care for- can handle wider range of water parameters (can withstand cooler water and can tolerate a wider range of pH and hardness levels)._
* _Can live with other peaceful community fish._
* Cons:
* _Can be territorial with each other, so it is important to provide plenty of hiding places._
* _May chase and stress out female guppies if they are kept together._
Female-Only Guppy Tank
* Pros:
* _Females are less aggressive than males._
* _Easier to care for than males - can tolerate wider range of water parameters._
* _Can live with other peaceful community fish._
* Cons:
* _Not as colorful as males._
* _Can be difficult to find in stores._
* _May not be as active as males._
Ultimately, the best choice depends on your personal preferences. If you are looking for a colorful and active display tank, then a male-only guppy tank is a good choice. If you are looking for a peaceful and easy-to-care-for community tank, then a female-only guppy tank is a better option.
If you do not want to breed guppies, you can keep both males and females together in a community tank, as long as you make sure that the tank is large enough to provide plenty of space for all of the fish. It is also important to keep the water quality high in order to prevent any disease outbreaks.
