ide say that you definatly have a boy. but i could be wrong because its still dark, but it just seems to have way too much blue on the cere to be a girl. if the see is dark blue then its a boy. no doubt about it. evan if it has a little bit of brown. girls normally have a white cere or tan cere sometime with a tiny bit of blue towards the bottom ill show you a pic to show you what im talking about. ok this is a female

this is a male

and evan if it is purpleish looking its still a male. it has to be really almost completly white or REALLY dark brown or completly tan to be a female. or white tan. not blue/tan. lol i hope thats not confuseing. but all in all it looks like a male to me. i would say now that you lightened it up 90%sure that its a male. but its still dark. and lighting can really play with the colors of the cere in pics. so i dont want to say for definate and be wrong ya know?
