A 125 is a battleground with those 2 fish. Generally only males will get the humps.

Give it more time. If it grows a nuchal hump it’s a male. RD’s often don’t get aggressive and confident till they hit the 6 to 7 inch mark then they will suddenly turn into savage devils, hence the name.
Also females can get a hump. I had a midas female with a big hump. Thats not a safe way to sex an amphilophus.
Thanks for the information. I was not aware females could grow a nuchal hump, I learn something new every day on this site!
I just did some research on this issue. What I found was that while RD/Midas females can indeed grow a hump they generally tend to be much smaller than the males and they are not seen with humps in the wild. Male RDs grow prominent nuchal humps both in the wild and in captivity. Females prefer males with a large hump as it indicates a healthy male with excess food reserves.
So if your Midas develops a large nuchal hump it is probably but not definitively a male. Hope that helps.
