dovii sexually mature at like 3". yours has:
- no dots on the gills or pelvic fins
- round dorsal/anal fins
it is a female
 
The gender differences in the genus Herichthys are also quite obvoius

Above are 2 femal Herichthys carpintus, note the dark are in the dorsal, and slope of the crainal profile.
Below a male, lack of dark color in the dorsal, and steeper crainial profile

Even as 1¨juvies the profile difference in males as females is apparent

I find the crainial profile is obvious in other Herichthys

This cranial profile is obvious in other genera

The genus Amatitlania and their related genera can also is have cranial slope differences

Of course there are a few new world cichlids where cranial differences are less distinguishable
