Body size matters for mate choice of the paradise fish
Description
Initially, we employed a generalized linear model to explore the impacts of focal fish sex (i.e., focal male or female), stimulus fish size (i.e., small or large), and sex combination (i.e., different sex or same sex) on mate choice and same-sex preference behaviors in the paradise fish. In this model, focal fish sex (i.e., focal male or female), stimulus fish size (i.e., small or large), and sex combination (i.e., different sex or same sex) were used as fixed effects, while the percentage of time spent in the selected area was set as the dependent variable. The activity level (i.e., individual swimming speed and PTM) was incorporated as random effects. If the model indicated significant differences either among or within treatments, independent T-tests were conducted within a stimulus fish size treatment to compare the inter- or intra-treatment differences. Moreover, to delve deeper into the mate choice and same-sex preference behaviors of the paradise fish, we evaluated the strength of preference (SOP) between partners under different treatments (e.g., focal fish sex, stimulus fish size, and sex combination)
