For contrast, here is a very different kind of fish. No eyelid line, a more horse-like nose instead of the bump, the scales are discreet (spaced away from each other) and more pointed (and no teeth showing, but that depends on the pose):
There's more than one illustrator in this manuscript and some of the noses are the bump style, but the rest of the fish is not like the fol 642 example.
