The average lifespan is about two to three years. Four is not unheard of if the fish is very well cared of.
Guppies mature differently depending mostly on tank water parameters. For example a colder tank will slow the maturation of your guppies but will probably also extend their lifespan. When your males start to colour up-they are most likely ready to reproduce, this should be in the 2nd or 3rd month. Females will be ready at this point too. Your males will be approx. 2 centimetres long, females a little bigger.
Fries (the term for baby guppies), are eaten by older guppies, but guppies are eaten by fish like tuna.
