I agree and understand the points you have made concerning “hybrids” or creating new morphs.
You are right; hybridization has nothing to do with different species requirements. The main focus for every hobbyist should be the health of their animals. I believe everyone here can agree to that. As you stated earlier these are not natural setting by any means. A terrarium is as far from nature as the frogs can be. That being understood we strive to put the least amount of stress on an animal as possible. With reptiles and amphibians identifying signs of stress can be difficult and only the most trained can successfully diagnose exotic species. Dart frogs, on a most micro level when compared to a large iguana and snake species pose even more of a challenge. Often our little friends can slip away without the slightest warning. The rule of not mixing species minimizes the invisible stress these animal display.
Now, onto the beaten issue of hybrids and man made morphs.
I consider myself an educated consumer. I am confident enough that I would not mistakenly purchase a hybrid animal without knowing it. That being said, I am not 100% certain that I haven’t purchased one in the past or won’t in the future at least not intentionally. First time buyers could mistakenly buy what they thought was a powder blue tinc or any other tinc and have it turn out to be a mix. Most tinc froglets are similar in coloration and certainly shape.
I like your enthusiasm for dart frogs Marcial. I even like that you personally want to own the prettiest frogs possible. That is normal and I think we all do, but where does the line get drawn? This is the vicious cycle:
1. Say you and I find two of the most beautiful tincs of the same color morph and breed them in line to develop their traits. We create the perfect powder blue tinc flawless in every way…
This is already happening now. Bigger and brighter frogs are more attractive and at shows they are more likely to be purchased.
2. The next step (where I believe you stand) is to take tincs and mix them together making a new color morph. This has already happened as well. Most of us can understand that desire to have a frog no one else has.
Now the hypothetical problems begin. Let’s say these frogs are just so astonishing that everyone has to have them…a sellers dream. Soon breeders all breed this ‘cash animal’ and we begin to see fewer and fewer natural morphs being offered. That may be fine to the common hobbyist or first time buyer, but what happens to the advanced collector?
As time passes a new trend catches on. This trend is to keep only natural species as mundane as they may be. But wait! Those previously common inhabitants are now harder to find. The prices certainly have increased for these animals so we look to the rain forests to import frogs and reestablish breeding colonies. But wait! They no longer exist or are so protected we can’t get our hands on them. Prices still climb. So now what do breeders do? The demand for the mutts has plummeted and in response they pass them off as the real deal. These mutts are unknowingly bred back to the originals. And so the slippery slope continues.
Is it ridiculous? Maybe, but it happened in the cichlid market. No one I know has a true “Green Terror” the fish has been replaced with ‘Gold Saum’ species. But we still call them green terrors. Flowerhorns and other hybrid species have crowded dealers tanks to the point where I challenge one to find a natural Oscar. We are bombarded with “Tiger, Albino, Red, etc, Oscars.” The once popular Madagascar cichlids are nearly extinct. Cichlids from lake Victoria which could be found in fish stores five years ago and now not found anywhere on the planet. I can honestly imagine this happening to dart frogs.
Fortunately due to the delicateness and higher starting cost maybe it won’t. I like that not everyone owns these creatures. Can me a snob, but I don’t brag about my leopard geckos for a reason. (Not to knock leos!!)
