Hihi I thought all the guppies we have today originated from the ancesters of the drainages of Venezuela......guppies are not local species you know. There are alien species but not classified as invasive alien species yet such as the sucker and african catfishes. We have our "longkau" guppies because it was brought in to combat Malaria & Dengue fever which plagued us a long time ago and is still now. So this runs a long way back which we find accustomed as our own species which is definitely not. So the fancy guppies where produced from generations of selective breeding & inbreeding of these Venezulans species. But I think we do have another slightly different species in USA in the waters of Florida which has bigger body sizes especially females. I think it was a crossbreed that created our huge female fancy guppy we have today.

Thanks for tuning in my lunchtime rambling.
