Does temperature affect sex ratio?


I just got my first spawn of cacatuoides and the temp was 82 degrees Fahrenheit. Will this affect the sex ratio? If so, what temp will help me get a more equal sex ratio?

Sorry wrong article! I wanted to link to this one: Römer & Beisenherz (1996): Environmental determination of sex in Apistogramma (Cichlidae) and two other freshwater fishes (Teleostei). However, it seems not to be available online. But it can be found in Römer's Cichlid Atlas, Vol. 1, Chapter 3.2.
