Consistent individual differences in behavior imply that individuals act in the same manner every time they encounter a situation while differing from others. While these differences occur in a variety of contexts in a wide range of organisms, how recent experience affects behavioral consistency remains underexplored. Male Siamese fighting fish exhibit consistent individual differences in behavior when both a male and a female are present. However, whether these responses can be shaped by immediate recent aggressive experience is unknown. In this study, males first were presented with paired dummy male and female conspecifics after they had been isolated to obtain a baseline, no-experience measure. Males then won and lost fights and were retested with the dummies after each fight. These three experience types (no, win, loss) occurred both when males did and did not have nests to determine the effects of nest presence, experience, and the interaction between these factors on behavioral consistency. Overall behavior did not change based on experience with the exception of male-directed tail beats. Repeatability values were affected more by having a nest than fight outcome. This study demonstrates that consistent individual differences in behavior to conflicting stimuli are fairly resistant to short-term aggressive experiential effects.
