I think that both species of stonerollers you have, oligolepis (largescale)
and anomalum (central) have some light patterning of darker scales along the
dorsal region. The big differences between the species involve scale and
pharyngeal tooth counts. And you're right, it's almost endearing with
stonerollers how much they like low falls and runs which they can move up
and down in with no problem.
