The cardinal trade supports many communities in the Amazon, and can be held as the perfect example of sustainable harvest. There is so much sketchy stuff going on with the collection of loaches, bettas, and many other Asian fish that I cannot include them in my defense of responsible collecting. The biggest example of these deplorable practices could be Schistura pridii, which are still very rare (thankfully) in the hobby and are presumably being poached out of nature reserves in Northern Thailand.
One thing we need to keep in mind though, is our role in all this as aquarists. As was the case with the celestial pearl danio, we are in a position to greatly advance the cause of conservation, and can choose to serve as a repository of species, breeding and preserving natural bloodlines for future generations.
