Can you get a closer picture of the vent? If it's pointed the fish is male, if it's short/blunt the fish is female. Below is a picture reference of my male MiDevil (notice the pointed organ).
I'd say female. If she is, it will eventually lay eggs (even without the presence of a male). However, this will only happen if your water is clean/stable, she feels comfortable, and the tank is of adequate size. Really nice fish.
