Latin American Journal of Aquatic Research, 2010 Poecilia sphenops was acclimated to two thermal fluctuations, each following a symmetrical and asymmetrical cycle. The critical maximum temperatures of the fish were significantly different (P < 0.001) between the thermal fluctuations: 40°C for the 20-29°
