Hard to tell. Looks female. Clean the glass and take it again. Looks like it has a skirt and it does look like the second section is bigger which would indicate female but photo angle and glass condition makes it difficult to be certain.
yep definently looks female. If you suspect that you might be keeping it with other males, which are less bulky and usually slightly smaller, be sure to look out for a white line going down her back. this could indicate that she's pregnant with eggs! Good luck with your shrimp 😁
