One cannot judge amphs by a few physical characteristics. Simply impossible.

FYI - According to one of the local experts, or the closest you will find to an expert on this subject, Lake Arenal midas were most likely stocked by locals, many years ago - so what their original genetics were is impossible to say, as that Lake is a man made reservoir. More than likely the midas from that body of water originated from one or more collection spots in Lake Nicaragua.

From a previous post on this subject; Lake Arenal is basically a land locked reservoir that was enlarged when a hydro electric dam was built back in the late 1970's. According to William Bussing (a well respected researcher in this area) in his book that was first published in 1987 "Peces de las aguas continentales de Costa Rica",


he states;

"the A. citrinellus found in Lake Arenal were probably introduced by man."



If the amphilophus in Lake Arenal were in fact introduced by man, then I think that it's safe to assume that those original fish would have been collected & transported from the closest place possible, which in this case would have been Lake Nicaragua.


IMHO, if you want a specific look, next time ask collection locations, or better yet pics of the actual fish you are buying.

Enjoy your new fish, looks like you got exactly what you paid for.

That is very interesting about Lake Arenal. Essentially, if the rumors are true, then the chances of getting genetically pure citrinellum from this location may be about the same as getting a genetically pure citrinellum out of a Florida canal. Difference being, the transplanted fish are merely closers to the source of the original species.
 
Pity we won't be around in a few thousand years to see if they evolve into 3 different sp like in the other crater lakes

Not exactly. From the various studies that have been performed over recent years, we know that it is a very rare event for citrinellum and labiatum to crossbreed in their natural habitat. (different story in a pond or aquarium setting) I have also never seen or even heard of labiatus being collected in Lake Arenal.

The reason for so many hybrid crosses within the pet trade, is due to the fact that in the 60's and 70's when these amphs were first being exported, those importing did not always understand what was what, and often the term "red devil" was simply used to describe the fish. Once they entered the ponds of florida things took a turn for the worse. Flash forward several decades of pond fish, and millions of hobby breeders, and impossible to say what one owns unless it comes from a trusted source, with a collection location attached.

The info found in the link that I provided previously is a prime example of why collection locations are so important in this hobby, at least if one plans to breed & sell fish.

I wholeheartedly agree about the importance of location points being stated. So if we eliminate labiatus from the genetic make up of these fish, one could plausibly assume these fish originated from a species of citrinellum or subspecies of citrinellum with marked phenotypical differences divergent of those found in the Lake Nicaragua populations, which exhibit the more "classical" traits generally associated with the species.

Or, there has been so much evolutionary pressure, that the introduced population has shifted traits so dramatically in the last 40 years or so, in order to cope with the new environment, what visually differentiated characteristics are starting to be expressed. To me this scenario seem less likely but not completely inconcievable.
 
I don't even think the OP is reading this anymore. Thoroughly shut down.
 
I can't speak to the OP's actions, but I would think that more information regarding the species heritage and collection point differences would be beneficial for future customers of vendors and perhaps the vendors themselves.
