pictures are not in focus. Assuming it is a mature fish, then the males has longer odontodes on the front edge of the pectoral fins as well as their cheeks. You cant miss it but it needs the pictures to be in focus to tell. Adult males are also larger than females in length.
Looking at the 2nd picture for relative size (which is all the 2nd picture is good for), the fish appears to be around 6 to 7 cm. The absence of long odontodes on the cheeks and pectoral fins on the 1st picture would indicate a female (not in focus, so is all blurry and cant really tell). Body shape is of a typical female but then it can also be a 'bloated' male.
