Hi, I owned a pair, and it is VERY hard to tell the difference, my clues were only in the courtship behavior, shortly before it turned bad leaving me with the loan male...
I'm sure with enough hands on and enough examples people will learn subtle differences, But I think it’s more hit and miss
on a side not ijust realized your canadian as well, would you care to tell me where you got yours I bought a pair and lost the female,i have had trouble finding more...
There is a store here close to Montreal in Blainwille and is a guy who like them a lot and he is selling them from time to time I will look for the phone number for you.
Don't quote me on it, but I believe that males are thinner and have smaller blotches on their sides and the females tend to be a bit thicker and have bigger blotches. And I think Males have more robust heads.
