Ooh that's kind of a tough question.... I am trying desperately to stay
away from the dreaded statement "they just look different" They are
only found in the Altamaha system so the only fish that you could
confuse them with is C. xaenura, which does look a little like
callistia, except gets alot bigger and has more anal fin rays (10-11).
For lack of a better comparison, I would venture to say they looks
probably similar to trichroistia or gibbsi, except the do not have
different colors on the fins. They typically has a yellowish fin
coloration and is uniform for all fins. The mouth is slighty
subterminal probably similar to callistia. In comparison to othe
Cyprinellas they are somewhat drab in appearance. They don't really
exhibit exceptional coloration during breeding season like xaenura or
callistia. But still a neat fish, and easy to keep.

Is the callesima similar in coloration to callistia?
