no chance they find their own companion and breed this can be done only scientifically at laboratory levels
No, guppies remain the same gender for the rest of their lives.
platy and swordtail are some beginners.
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.
A platy may begin to breed starting around 4 months of age
I don't think so.
Only guppies breed with guppies naturally.
The guppy, platy, swordtail, and mollies are the mainstays of the fresh waters fishes.
A Platy is a Platy it is either a Xiphophorus maculatus or X. variatus. Colour does not matter at all. They are all the same species and can interbreed. They can also cross breed with Swordtails (Xiphophorus helleri).
you can't force them to breed but you can put 2-3 females with 1 male in a separate tank and eventually you will get fry(babies). In my tank i have mollie fry and previously had platy fry whish has now grown up and are adults
Yes. They can cross breed because they are of the same species.
Guppies first, then mollies, platies and swordtails all grow at about the same rate.
Don't own female guppies if you don't want youngsters.
id say guppies, they breed like rabbits
