Bettas are native to Thailand, guinea pigs Peru, axolotols Mexico, etc etc. All pets were once wild. Dogs used to be wolfs.
While they need a very responsible and knowledgeable owner, I don't think that the fact that they come from your country alone makes them bad pets. Just saying, don't mean to start a debate here.
Bettas and axolotols are also not very high functioning animals. There is little difference in the behaviour of my wild-caught bettas and my captive bred bettas.
However, I have never liked the idea of having exotic animals as pets. Particularly mammals and marsupials. Dogs, cats and most popular species of livestock have been domesticated for thousands of years. Most breeds of dogs you would have to go back generations before you even found a wild ancestor.
Animals such as wolves, sugar gliders and primates (I still cannot believe some places allow the average person to own a chimpanzee) have not. People underestimate how fast and how unpredictable a wild animal (even one that has been bred in captivity) can be.
Calling them 'sugar bears' makes it sound like they are trying to appeal to people using the cute factor of these animals. I think that is wrong.
It's like how I thought it was wrong for there to be an avairy with a pair for sale at our local stock and feed store. We have nature parks to observe these animals in a essentially natural environment. They really don't need to be kept as pets.
I can see why they chose sugar gliders over something like a brushtail possum. Because they are cute, and cute is unfortunately what sells.
