My guppy keeps trying to turn upside down under my female Platies and keeps following her around . I only have male guppies . I heard they can can crossbreed with Platies so is this what he's trying to do? is my guppy trying to mate with my Platies? Please answer. Created by Troy Butler. pets-en - fish-en

Male guppies will try to breed with any female fish it can find, not just Female guppies, but the only way you can crossbreed fish is if they are very closely related species. Platies and Guppies are not close enough related to be able to crossbreed.
