I need a male as well, I have a female that everyone in the tank is trying to breed with.... Let me know... (she was a sub alphae male before the hormones faded away, or, just a typical balto gal.....)
In my experience, male moori have a bigger head bump and longer fins. They also act "male"... while females tend to be somewhat smaller, smaller head and heavier body.
Not as dimorphic as some "haps" but definitely possible to tell...
