GBR's are much more colorful than Bolivians and the demand for them is greater than Bolivians as well. Bolivians aren't "better" than GBR's but it's very common to see poor quality GBR's as they are mass produced in Asia where they are subjected to growth and coloring hormones that weakens the fish and shortens their lifespan. This has caused the common misconception that GBR's are more fragile than Bolivians which isn't the case at all. Good GBR's obtained from a breeder will be just as healthy as Bolivians, which often are wild caught specimens.
I meant that I heard that they were more lively and active, that's all.
