The global climate change and ocean acidification brought about by the anthropogenic release of carbon dioxide gas into the air is considered one of the greatest problems facing marine life. In this research, the interactions between two species of fish (the gold mollies and tiger barb) were investigated under two different environmental conditions, an elevated temperature of 28 °C and a low pH of 5 and a normal pH of 7 and a normal temperature of 24 °C. The mollies at pH 7 and a temperature of 24 °C exhibited scary interactions with the tiger barb. They were scared and ran fast away from the tiger barb. At the same time, the mollies at pH 5 and a temperature of 28 °C interacted normally as though both species were one species showing behavioral changes due to these two stressors (pH 5 and elevated temperature 28 °C). This could be the only research that has addressed how the kinematics and swimming interactions of two species of fish changed in response to elevated temperature and low pH.
