Correlation of activity and weight in comet goldfish (Carassius auratus) at differing water temperatures.

Correlations of activity and weight at three water temperatures, 20 degrees, 26 degrees, and 30 degrees C, were examined in the comet goldfish (Carassius auratus). For the 12 subjects general activity scores increased as water temperature increased. Heavier subjects were more active at low temperatures while lighter subjects were more active at higher temperatures.
