So, including "Surinam" in the name is - what? A misdirection so people look for the fish in the wrong place? G. taeniopareius is an Orinoco species, from a considerable distance west of Surinam. There are also some things about the fish in the photo that don't exactly match what I've had and seen as taeniopareius. Not saying it isn't, but it didn't strike me as taeniopareius at first look. Strong similarities, but not quite the same.
There are two kinds of error: blind credulity and piecemeal criticism. Sound skepticism is the necessary condition for good discernment; but piecemeal criticism is an error. - Egyptian proverb
