Is there a pecking order inside a crappie school?

Honestly: no documented dominance hierarchy, and probably none worth the name. What looks like rank is mostly size-sorting — crappie school with similar-sized fish because matched swimming speed and shared predator profiles keep the group efficient, so a school of 15 cm (6 in) fish and a school of 30 cm (12 in) fish are usually separate schools, not one layered society. The practical takeaway is real, though: if you are catching small fish, moving a short distance or changing depth often finds the bigger year-class rather than culling through more of the same.
