- Goldfish are one of the most common aquatic pets. The average temperature to maintain healthy goldfish is between 72-75 degrees Fahrenheit. However, it is not unusual to find goldfish keeping office workers company in frigid cubicles as low as 68 degrees Fahrenheit. Mary noticed her goldfish opened and closed it’s operculum (protective covering for the gills) more often when the temperature in her office was warm. Worried, she may be harming her pet by keeping her office so cold, Mary set up an investigation to test the impact cold temperatures had on her goldfish’s respiration rate.
