Re: unknown fish

Maddening is only half of it! Females can be hair-tearingly difficult to ID.
Look at the problems we have with A. roraimae. Kullander described it as a
species based only on female & juvenile specimens. We now know that it is a
gibbiceps-like fish, but is it A. gibbiceps or a closely related fish? Your
guess is as good as mine, although Koslowski writes that Stawikowski brought
back gibbiceps-like fish from the uppermost Rio Branco of Guyana that just might
be a different species.

You're absolutely right about colors. Other than the black markings colors are
usually only useful in determining color morphs.
