Thanks for the input everyone. I'm still not 100% convinced it's a melanurus though, the melanurus I've seen that are still female like her have more orange in their face already. Vrolik's Wrasse, (Halichoeres vrolikii/chrysotaenia) was another on the list of maybe's... I'll try to get some better pictures. Maybe I'll just have to wait a couple more years before she goes more terminal phase.
