I am not suyre they are anywhere near extinct in the wild Haych and Kelly528. They are readily available in the US as pure wild types from both Swampriveraquatics and Tampafishman1 along with a large number of other registered small time breeders, like me. I have them coming out my ears so selling a few will not affect my numbers for more than a week or two. I intend to sell off as many adults as I can at the Circle City fish club auction in November and would have sold many last weekend at the Tri-city club auction in Peoria, but I needed to work the day of the auction. The Laguna de Los Patos original location is severely under the threat of having no surviving fish due to habitat destruction, but nearby small creeks have been found to contain the fish in large numbers by various collectors. The species definition of Poecilia wingei does not name the specific location as the deciding factor but the characteristics of the fish instead. Those fish were not collected at Cumana but at other locations, so an "endler" may or may not be the same thing as the recognized separate species. Meanwhile, those of us with "pure" natural fish and their progeny can claim class N endler status but it gets a bit shaky when we claim anything much more than Poecilia sp. with collection location information. I personally find it easy to tell my fish from almost any guppy or endler cross that I have seen but that does not make it a separate species that needs protection. It is no more or less than an admission that we can tell fish apart but do not know enough to determine their species really.
