Male Or Female Rosy Barb?

[sbga]

I have a bright orange neon rosy barb, almost the orange color of a goldfish, and I was wondering if it's a male or female. It doesnt have black on the fins like most regular male rosy barbs do, but I've seen pictures of some neon males without black on their fins. It has been nipping at the female rosy

This is just what I've been TOLD by other people but they say the males are a lot brighter in color than females. Hope someone with better input comes along!
