yeah, there is no sub species, so to speak, but they are named by their collection points....unless you know were they where collected from its hard to make a positive id....sorry, but that is why they call them the brasiliensis COMPLEX....im currently in dispute with a dealer who sold me iporangensis, under the name of bahia red......nice fish but clearly not bahia reds.....and clearly not worth $400 for 6.....i'm quickly learning that the whole geo scene, is clouded in misrepresentaion, which wouldn't be a problem, except they are so bloody expensive!!! and when you find that you havent got what you paid for, it kind of takes the shine of that section of the hobby!!!
