Bloodfin tetras (Aphyocharax anisitsi) and neon tetras (Paracheirodon innes) have been observed peacefully co-existing under ideal conditions in home aquaria despite being geographically separated in the wild. In home aquaria, they behave as if they were all the same species without competition that is normally a defining characteristic of the bloodfin tetra. This research is investigating the behavioral patterns of co-occurring bloodfin and neon tetras in aquaria under varying temperature increments that emulate the projected rise in global temperature. Our hypothesis is that competitive behavior will change as environmental conditions (e.g., temperature) change, potentially due to increased stress to individuals. This study will reveal information about how future climatic shifts can impact the ability of these species to interact if introduced together in the wild, and also seeks to determine whether biogeographical co-occurrence is likely under climate warming scenarios. Our ultimate goal is to determine whether climate change will put the diversity and native habitat of these popular aquarium species at risk, and more broadly in determining potential impact on other tropical species.
