So, I cleaned the jars again and this time I sectioned them all off by gender. I have A1 to A26, and then it starts at B1 (labels for jars) and goes up. I have about 35 or so jarred.
There are slightly more males than females.
- Shape and length of body
- flaring habits
- body color
- ventral fin length
- anal fin length
- submission lines
Most of the males have darker bodies, or have colored up a lot faster than most of the females.
Most of the females have tiny rounder bellies, while the males (most) have seemingly inherited mom's thicker body, but without the bellies.
The ventrals on the males are fuller and longer, the females have shorter ventrals.
Anal fin on the males are longer, by double at least.
Flaring and beards go hand in hand, the males will flare, expanding their rounded caudals, showing off or attacking through the glass while the females show submission stripes, and try to dart through the glass excitedly.
There are a few "unsure" ones, who were put on the female's or male's side. There is one male with a lighter body, and a few females who are a bit darker than the other females.
EDIT: The green/gold is a female, considering the body shape, ventral length, etc.
