Was wondering if this is a female or male .
It looks like a female to me,I might be wrong but I think males have red on them.
I say male because of the orange on his/her throat
It's stomach looks rounded which made me say female,when I looked at pictures the males had much more color on them.In some of the pictures some of females had orange like that,it might be a young male that hasn't gotten much color yet.
I agree with Fallen Owl; it's a male. The orange throat, longer, more angular dorsal fin, and the spiky anal fin are dead giveaways.
I guess dorthy is now Theodore.
