Well, both Notropis stramineus (sand shiner) and N. amabalis (Texas
shiner) are common in the Colorado R. drainage, with N. amabalis being
the more common fish in clear, cool waters, moderate to swiftly
flowing, N. stramineus being more common in more turbid, warmer
locations, and slower flowing situations. I can't seem to see your
photos. I just get an error message when I try. However, N.
stramineus (what you are calling N. ludibundus) is easily told from N.
amabalis. The latter is much more silvery, much less plump, with a
bigger eye. The former is more a straw color, and has what have been
called "puppy dog tracks" in the form of a series of paired black
spots on each lateral line scale subtending the l.l. pore.
