Some people have a hard time telling if a molly is a male or a female. or if its pregnant. If this is not you then i suggest you leave. But, if it is. than I will show you! (these are my own pictures). see pictures from left to right.
This is your classic female Black molly.
this is the
gravid spot on the pregnant female molly.
And this is the male(left) trying to get the female(right) to mate. notice the
gonopodium on the male.
Heres the difference between a pregnant(top) and non-pregnant(bottom) molly.
And heres the outcome a month or so later!
Hope this helped out anybody who needed the info!
