Temperature was effective in goldfish number of breaths per minute. As water temperature decreased from 22℃ to 10℃, the average number of breaths also decreased. The mean of the average number of breaths is 69.24. The number of breaths in the study ranged from 16 to 135 breaths per minute. The null hypothesis, that the temperature of the water has no effect on the number of breaths per minute, can be rejected. The results support the alternative hypothesis. The control fish number of breaths per minutes remained constant in the study. Goldfish are ectotherms animals; the goldfish body temperature depends on the environment temperature (Santos et al. 2012). Eurythermal freshwater fish and can survive in water temperatures from 0–4°C during the winter to over 30°C in summer (Santos et al.

The present study suggest goldfish are ectotherms and temperature effects respiratory rate. The decrease of the water temperature relates to the goldfish respiratory rate. The body temperature of the gold fish influenced the rate of respiration. Although the data reflects as temperature decreased the goldfish number of breaths also decreased, further errors could have occurred in the experiment. Each groups ability to maintain the set water temperature and the count of the number of breaths per minutes may have affected the results in the experiment. A further extension of the study includes increased number of replication of the experiment to allow more accurate set of results. Also the experiment could have allowed the fish adjustment temperate to have been longer in the experiment. It has been found in previous data, goldfish respiratory surface area alters in response to temperature (Sollid
