A platy is a type of tropical fish. It is not a quantity or measure so one can not have a "platy of" anything including guppies.
I don't think so.
What are guppies
Male guppies chase pregnant female guppies because they are trying to mate with them and fertilize their eggs. This behavior is natural for guppies and is a part of their reproductive process.
yes.
Male guppies are considerably smaller than females of the same species.
If you have a male and female Platty together I can guarantee that the female is pregnant (gravid) no matter what you think.
Male guppies have a pointier anal fin and a bigger tail than the female and the female is larger than the male.
yes i have one my white female bred with a black male
Female guppies stay very plain to help with camouflage. Male guppies get color to attract females.
They do mate! As long as you have 3 females with 1 male and you keep the tank well planted and at the right temp!
Guppies are livebearers. So they don't lay eggs. Male guppies WILL eat their own baby guppies. They will eat any baby guppy they see. It doesn't matter if it's their own or some other guppies'. Male and female guppies eat baby guppies.
Yes that is enough. You usually want to keep a two to three female to one male ratio. The male will constantly try to breed with the females. If there was only one the female you get stressed out and die. So make sure to keep two to three females
