Ive only ever owned one umbee (big male) and he looked strikingly similar but I'm also no expert so my opinion is exactly that, an opinion. The animal guy seems to know his stuff pretty well though so if he says female Im inclined to take his word.
thank you all for the in put. bit sad hard too get them where i live, still a nice looking fish ill just have too hunt down a male if it turns out to be female.
