The butterfly splitfin (Ameca splendens), native to Mexico, is critically endangered due to water pollution, competition with nonnative species, and habitat loss. Conservation efforts by various groups, including aquarists and hobbyists, have focused on raising awareness, developing captive breeding programs, and preserving natural populations and habitats. Educational institutions, such as schools and colleges, play a crucial role in these efforts through integrated lesson plans and captive breeding projects. At Miami Dade College, during the Fall and Spring semesters, we conducted a study to compare the reproductive success of butterfly splitfins in different environments. Paired butterfly splitfins were raised in large indoor aquariums and outdoor tubs over several months to determine whether natural or controlled conditions, indoors or outdoors, would yield more offspring. Our results indicated that while more offspring were produced in outdoor tubs, the difference was not statistically significant. This suggests that both indoor aquariums and outdoor tubs are viable breeding habitats for these fish. Future research will extend this project into the summer months, addressing the additional challenge of high temperatures in Miami.
