That's cool that your LFS guy lets you see the wholesaler's list.
What makes me think "macrochir" for our fish is the lack of interorbital papillae and nodules, and if you look at our fish's mouth, right behind where its teeth are located, you can see what appears to be the telltale black marking. This black marking supposedly looks triangular if you can actually see it, but I haven't seen this cuz the little sucker won't say "AHHHHHH". That being said, its "hump" is pretty prominant, which suggests diabolus, but I'm still holding out for "macrochir".
