Noob in Need of Help Sexing CRS

[Jd7]

I have only been keeping CRS for a short time and with a few issues with temperature (got up to 27.5), having mostly males and having relatively young shrimp I haven't had any success getting berried females although it has only been a month and a bit. Not sure if this is a female or male, I'm pretty sure its a female but not too sure. I have compared the antenna and  body size but without a proven female its a bit hard for me to say.

 

Thanks for any help you can offer.

first pic IMO Is a female, you will struggle to have them breed at that temp or keep your shrimplets alive. Optimum temp for CRS you want around 22-24 max.

That is the same shrimp. And yeah, I have gone out and purchased a fan about a week ago, its kept it below 25 degrees (21-23 mostly) but in Brisbane at the moment its been hard to do that unfortunately.

 

Thanks so much for you help :)

Yep, definitely looks like a female to me

Ahh great, thanks guys, I actually just saw an obvious male 'attack'/chase another shrimp not 5 minutes ago so maybe tomorrow morning I will be lucky with a berried female. fingers crossed! haven't seen a molt though so maybe he just stole some food, there are so many hiding spots in my tank that not seeing a molt may not mean much. being optimistic

Best thing to save up for in shrimping is definitely a chiller down the track :) You will enjoy the security of having one  and save money in the long term :)
