 Schools of adults form to migrate to shallow pools with slow-moving water and spawn between rocks and boulders, depositing the eggs in crevices between these.This species is considered Near Threatened by the IUCN, mainly due to the adverse impact of the introduced smallmouth bass ("Micropterus dolomieu") on its population.The most drastic declines have been in the past, and though the species is still declining it is not doing so at an alarming rate; wherever the bass has not become established yet it is actually rather plentiful.
