As juveniles, they grow at a rate of about 0.2 mm (0.0079 in) per day, but growth is highly temperature-dependent. Growth rates of juvenile mosquitofish reach their peak when the water temperature is within a range of 24 to 30 °C (75 to 86 °F), depending on resource availability. [36]
This species thrives in water between 31 °C (88 °F) and 35 °C (95 °F), and seems to be able to acclimate to temperatures above and below this. G. holbrooki has been shown to survive in water with pH and chemical levels known to kill other fish species, and prefers to live in areas where the water flows at a slow pace, is clear and without ...
