So as the temperatures are creeping up in Australia its probably a good time to discuss temperature for your Neo's. Since i have a lot of prego females in my tank i was wondering how much the temp will effect the offspring male/female sex ratios since i want to maintain an optimal breeding ratio and don't want a tank full of males. Ideally the temperature should be around  (21-24C) but i have been noticing lately my temps have been going up above this to (25-26C). Since the sex of shrimp seems to be directly related to temperature to remain at a 50/50 ratio of males/females it is ideal to keep a temperature of  23 degrees.  To maintain optimal breeding i have started to make a few changes to my shrimping practices. Reduced the time my lights are on from 10hours to 6hours, popping in a few ice cubes when i am away at work and the A/C is not on ( if I know its going to be a stinker), leaving the top of the tank open to encourage evaporation and not trap in the heat. by making these changes i have been able to stay within the ideal range of  (21-24C). I have also attached a chart to understand temperature vs sex ratio. Feel free to share your experiences.

26C for me, been up and down and that gives the best results imo.

what type of ratio are you getting Alfie m/f compared with the chart?
