Its not a fake GT. There is alot of debate about whether the GT's commonly found in LFS's are truely a. rivulatus or not. My non-scientific, this is just what I think, theory is that the ones we have readily available today are just so far removed from the rare wild-caughts that they have adapted. While the colors are similar, the wild caughts have duller colors. I think that could be because of the differences in diets. Over time, the manufactured foods provide more pigmentation and perhaps that passed on to offspring. I'm not a biologist or a zoologist or an ichthycologist so I would never say this was true, just my thoughts on it.
