" Environmental sex determination by temperature could be revealed significantly in 33 Apistogramma-species and in Poecilia melanogaster. In some, but not all, Apistogramma species pH also influences the sex ratio, whereas neither temperature nor pH affect the sex ratio of Pseudocrenilabrus multicolor victoriae. The sex in offspring of A. trifasciata is determined within a sensitive period of about 30 to at least 40 days after spawning "
