, i think its female.REC;1126043; said:
yea i see your point on the head but look at the top fin on the GT u posted now look at the top fin on my gt mines way longer but idunno hey u could be right either way im happy with the way he/she is turning out
I'd say male based on the dorsal and anal fins along with the more elongated body.
Nuchal hump is by no means a sure fire way of distinguishing male from female, for any species. The fish being wild caught wouldn't make a difference in nuchal hump. Genetics play a part, sure. But so do many other factors, tankmates, diet, stress, water quality, etc.
REC, look at how chunky the body of the female you posted. Then look at the body of the OP's fish. Also look at the pictures you posted of males. I can see the blotch on all of them, albiet faintly on some. The dark makings are stress related, not sex.
Here are some males and a female I've caught over the years. (Introduced to some ponds on Oahu.)
Male.

Modest I see your point in what your saying but its still a toss up and genetics play a large role and being wild should make its genetics far better and this is a wild specimen so being wild does in fact play a huge role. The pictures you posted simply proved what i was saying earlier on the knochal hump hell all the males you posted have it and the female doesn't. I also said I had heard some opinions on the black dot but in no way did I say it was a tell sign for being a female. The pics that i posted of my female her fins were a bit shorter then normal due to a small umbee I had at the time nipping her fins. Also she was a short-bodied Gt so looking at her shape means nothing. If in fact his fish is male then having no hump makes me question whether the source we got them from was full of **** on them being wild. I've never seen a wild male saum have such a rounded head as Chev's. You also mentioned that the knochal hump doesn't determine sex, I disagree with you on that, there are some species of fish like RD/MIDAS where both male and female have humps but in fish like Dovii and Saums only the males get the knochal hump.
My photos don't really help all that much, as I only took photos of large (11-13") males and one 9" females. The smaller fish I caught weren't worth photographing.
I'd say captive bred GT's have a greater chance of developing a nuchal hump, as humans artifically select the males who develop a hump to breed.
As I stated, wild vs. non-wild really shouldn't play any significant part in nuchal hump development.

GT's hump comes and goes, and has nothing to do with being wild. The subdominant or young males often don't show any hump.
Here is a picture of my male when he was the dominant GT in the group.
A month later, he lost his hump...

The 13" male is the third one down in the photos I posted. This is him as well.
That's an 8" diameter pot he's next too, for size refrence. Probably weighed just about 3lbs.

mmm well humps come and go due to a variety of factors mentioned above. i think maybe post a picture in a couple more days when he/she is feeling better. then we might be able to better guess.
