We observed the behaviors in six fantail darter spawning events and produced a model describing the probability of any sequence of behaviors between an egg's deposition and its fertilization. Of the 12 different behaviors we observed, “quiver” and “rest” were the most common for both males and females. Courtship and spawning behaviors may be ritualized, as there was no apparent variation in how the behaviors were performed by different individuals. This could also result from a limited sample size. However, breeding pairs differed with respect to the order in which the behaviors were performed. In addition, we found that courtship behaviors occurred through all phases of the spawning events and that the largest males in the study were the only males to successfully mate with females.
