As a life long hobbiest over 40 yrs.
I have learned that many standards in the hobby began as "hybrids" ,I
wont list them all, do the research you will amaze yourself. And if you know anything about Darwinist theory you will understand that "cross breeding" is a necessity in the wild for evolution ,species diversity and species success.
Many pureists in the hobby will discredit "hybrids" . Its funny how this transalates to human nature in general the analogy would be "fish Racists"lol
Having said that I personally am a "fish Racist " as well..lol becuase I do not feel that humans should on a Mass production level, such as Asian Flowerhorns, attempt to alter or modify natures natural progression.
The problem with this logic, yes I fully admit it , is that many of the specimin that I have mainatained ,studied and seeked over the years are
the result of such manipulation by mans hand.
I give you various Carassius, betta splenden, many of the 3500 + species of cichlids and even Marine species.
Now along with this distain,I carry the knowledge that many species in the hobby may unfortunately make the Invasive species list of many countries.
Flowerhorns are Uber Agro introduced to the florida everglades or the limited marshlands of the phillipines this "frankenstein" becomes
the equivilent of a pandemic to the native species, ecosystems and biotopes. the Nile Perch is an example of what our hand has done to the ecosytem the damage to the rift valley lakes and thier diverse species will never be rectified, lake victoria has seen the extinction of 200+ strain of cichlids.
Wth all this in the back of our minds it is no wonder why Some knowledgeable Aquaholics "hate" hybrids, until we one some...lol
