Male only guppy stocks

[rasbora]

I just move my female guppies to other tank, because they were harrassed by the male guppies everytime. Will male guppies become stress because no female guppies in the tank ?

Bachelor tanks usually work out quite well, without the females the boys play very well together. They can be very colorful and active tanks.

Sometime I see the male guppy harrassed a female platy. Is it usual for guppy ? I dont think the guppy can make the female platty to be pregnant. Am I right ?

They might harass them but they can not cross breed. Mollies and guppys can interbreed as well as swordtails and platies.
