The chances of it breeding with its own species is more likely then it breeding with any other species..... my point exactly.
Lol sure... I'm sure a male Midas is more inclined to breed with female Midas over a female Red Devil...
I can see them breeding with a species that is similar to theirs over one that is different but that doesn't mean they will ignore another species to breed with their own. They are gonna breed with the best suitable mate.
