When it comes down to it you have to be able to tell by the behavior, structure of the body and fins, and lack of ovaries.
Moot point now since it's definite that this is a male but I didn't want a NOOB reading this and thinking that no flare = girl.
On a related note, I have females that flare all the time and they are most definitely female.
