Male or female black nasty

  • We are currently upgrading MFK. thanks! -neo
And the other one?

I’m sorry I should have specified, I think their both female.

I’m by far no haitensis expert I've never kept them. So hold out for other opinions, I only know what I’ve read, and seen here. And atm I vote female.

The dark area in the dorsal, and some other areas, tend to be female traits.

Np ty tho
 
duanes duanes that being said. 2 of the 3 have the female traits, is it safe to say that the last one (all silver) can be or is male? Or too small to judge? Or it’s a dominance thing? They are all in the same tank but divided.
 
I couldn't tell much by the first pics, to blurry and dark, especially when enlarged, but I was able to enlarge your last pic a bit.
Could be a male, but the fish is really a bit too young to tell, I couldn't tell with mine until they were 4-5".
And the haitiensus in my pics are about 8-10" for the female, and 12-14" for the male.
