Carpintis juvenile sex?

[sodas]

Hello eveyone!
I bought this carpintis a couple of monhts ago . He was tiny and growinng really
fast.
Can anyone take a guess?

 

[ehh]

Ibthink ice read that females develop a dark spot on their dorsal fin. Not sure at what size does that happen though.

Yea but i ve read that it might not happen that often in escondidos and mine was sold as an escondido. I ve also read that males have dots under the eyes and females have lines instead.
Is that any accurate?

Tbh when I had my carpintis sometimes the black on the dorsal would be non-existant, and a second later be there depending on mood at that size. However my girl kept it all the time once she hit 3in

Here's a female to compare

here's a male


I find the slope of the profile is a good clue, the females have a more streamlined profile, males steeper, here's a pair together below, in spawning colors, and note when spawning, both deveope color in the dorsal

another shot of the female below

How big is the fish? Shape says female to me if the fish is more than a few inches.

I agree with axs377 that it looks female from the shape.
Even when very small, males tend to have a steeper profile. Below are the pair as above, but when they were only at most 2", and the males seem obvious to me.

The fish is 3 inches max.
Must be a female then
Was hoping for a male. Thanks a bunch !
Beautiful pair !!!
