No notropine minnows make nests; they are all broadcaster. However,
taillights are known to spawn over Micropterus nests, so they are
facultative nest associates.

Cowell and Barnett (1974) report FL taillights spawning late March to early
Oct. a 23-32C. In the aquarium, eggs held-in-23C hatched 60-72 hr after
fertilization. They mature in 6-9 months and usually live for just a year
(in the wild).
